On September 16, 1931, three underworld figures entered a Detroit apartment believing they had an opportunity to negotiate peace.

Within minutes, all three were dead, victims of an ambush that would help unravel Detroit’s notorious Purple Gang.

The killings occurred inside Apartment 211 at 1740 Collingwood Avenue, a residential address transformed into a notorious crime scene.

What appeared to be another gangland execution became a turning point in the struggle against organized crime.

The victims expected a discussion about outstanding debts and strained relationships involving Detroit’s lucrative illegal liquor business.

Instead, they encountered armed men connected to one of the city’s most feared and powerful criminal organizations.

The attack was brutal, but its ultimate consequences were even more damaging to the organization responsible for it.

A surviving witness would describe what happened, helping prosecutors accomplish something that had repeatedly appeared almost impossible.

Three major gang figures received life sentences, and the Purple Gang’s reputation for invincibility suffered an extraordinary blow.

Understanding why this happened requires examining the criminal empire that Prohibition helped create along the Canadian border.

During the 1920s, Detroit occupied a uniquely valuable position in the rapidly expanding American market for illegal alcohol.

Canada lay directly across the Detroit River, creating opportunities for smugglers willing to challenge federal prohibition laws.

The United States had prohibited commercial alcohol production and distribution, but public demand remained extraordinarily difficult to suppress.

Detroit’s industrial economy provided thousands of potential customers, including automobile workers earning wages in the rapidly growing city.

For ambitious criminals, the combination of available liquor, nearby international borders, and strong demand represented an enormous opportunity.

Illegal suppliers transported alcohol across waterways, moved shipments through warehouses, and delivered merchandise to establishments throughout metropolitan Detroit.

Speakeasies and other illicit drinking establishments offered customers access to alcohol despite increasingly complicated efforts at federal enforcement.

Bootlegging became a highly profitable business, creating opportunities for both independent operators and increasingly organized criminal syndicates.

The Purple Gang emerged within this environment, eventually establishing an especially violent reputation among Detroit’s competing underworld organizations.

Its members became associated with hijacking, extortion, gambling, intimidation, and the protection of illicit liquor distribution networks.

The organization also cultivated relationships beyond Michigan, participating in criminal arrangements extending into other important American markets.

Chicago represented an especially valuable connection because its underworld contained powerful buyers and established networks for liquor distribution.

The Purple Gang’s influence was never completely uncontested, but its reputation made many competitors reluctant to challenge it.

Violence became central to the organization’s methods, discouraging rivals and frightening witnesses who might otherwise cooperate with investigators.

Police struggled to secure convictions when potential witnesses feared retaliation against themselves or members of their families.

This atmosphere helped powerful criminals operate openly while authorities encountered repeated obstacles bringing serious cases to successful prosecution.

The Purple Gang’s most recognizable leaders included members of the Bernstein family, particularly Abe Bernstein and his brother Raymond.

Abe developed a reputation for criminal organization and strategic relationships, while Raymond became associated with particularly forceful enforcement.

Their organization was not a perfectly centralized empire, but an alliance of ambitious criminals with overlapping commercial interests.

Members cooperated when profits justified cooperation, although personal rivalries and disagreements continually threatened the stability of their partnerships.

The organization also benefited from connections with smaller smuggling groups operating across the waterways between Ontario and Michigan.

One important affiliated network became known as the Little Jewish Navy, whose members participated in transporting Canadian liquor.

These relationships offered considerable commercial advantages, but they also created disputes over profits, territory, and individual independence.

When affiliated operators challenged established arrangements, disagreements could quickly escalate beyond the ordinary conflicts of illegal business.

The stakes were particularly dangerous because criminal participants could not safely rely upon conventional courts to settle disputes.

Instead, threats and retaliation often replaced legal contracts, encouraging increasingly aggressive methods of enforcing underworld financial obligations.

Detroit had already witnessed how dramatically these methods could escalate during a notorious apartment shooting several years earlier.

In March 1927, rival gangsters were killed at the Milaflores Apartments during another notorious episode of organized violence.

That attack demonstrated the terrifying potential of automatic firearms within disputes involving Detroit’s increasingly sophisticated criminal organizations.

Investigators confronted numerous suspects, but the difficulty of obtaining reliable testimony continued frustrating efforts to establish criminal responsibility.

The Milaflores killings became part of a wider history of violence accompanying the Purple Gang’s expanding influence.

Detroit also experienced intense labor-related intimidation during conflicts involving the city’s cleaning and dyeing industries in the 1920s.

Gang figures became associated with extortion, bombings, and efforts to control businesses through threats rather than legitimate competition.

These activities demonstrated that organized crime extended far beyond illegal alcohol distribution into commercial life and labor disputes.

For ordinary residents, gang violence represented more than an underworld problem confined to criminals fighting other criminals.

Explosions, shootings, and intimidation threatened neighborhoods, businesses, workers, and anyone unfortunate enough to encounter a dangerous confrontation.

The Purple Gang’s apparent ability to escape serious punishment reinforced widespread fears about corruption and the effectiveness of policing.

However, the organization also contained weaknesses that its public reputation for violence could not permanently conceal or eliminate.

Its members depended upon unstable partnerships, illicit credit arrangements, and trust among people whose interests frequently conflicted.

Those vulnerabilities became increasingly important as three ambitious underworld figures entered Detroit’s competitive bootlegging and gambling businesses.

Their names were Herman “Hymie” Paul, Joseph Lebowitz, and Isadore “Izzy” Sutker, figures connected with Chicago’s criminal underworld.

Accounts of their earlier activities describe conflicts with operators associated with Al Capone’s powerful Chicago criminal organization.

The men eventually established themselves in Detroit, pursuing opportunities within gambling operations and the illegal liquor trade.

They became associated with the Little Jewish Navy, although their commercial ambitions brought them into conflict with established partners.

Their willingness to pursue independent business reportedly strained relationships with people who expected loyalty and financial cooperation.

In the criminal economy, outstanding debts represented more than accounting problems because they also challenged perceptions of authority.

A failure to pay could be interpreted as dishonesty, disrespect, or evidence that another group lacked sufficient power.

Historical accounts describe disputes involving gambling losses and liquor transactions that contributed to the growing hostility surrounding these men.

Some retellings contain elaborate details about diluted whiskey and supposedly manipulated bets, although those particulars require cautious interpretation.

What is established is that disputes over money and criminal relationships preceded the deadly meeting arranged in September.

Ray Bernstein occupied a central position in the Purple Gang network and became closely associated with the subsequent plot.

The victims believed a meeting offered an opportunity to resolve their differences rather than provoke further dangerous confrontation.

An intermediary named Sol Levine became essential because he maintained connections with the men on both sides.

Levine knew the intended victims and also had a relationship with figures connected to the Purple Gang.

That position made him useful in arranging a meeting that appeared credible to people already concerned about their safety.

According to historical accounts, Bernstein presented the gathering as a friendly discussion about future business and financial arrangements.

The planned location was an apartment building on Collingwood Avenue, situated away from the usual gathering places of bootleggers.

Its residential setting offered an appearance of normalcy that made the planned encounter seem less threatening than expected.

On September 16, the three prospective visitors accompanied Levine to the apartment where the meeting had been arranged.

The address was 1740 Collingwood Avenue, and the meeting took place inside Apartment 211 of the building.

Their decision to attend demonstrated how effectively the organizers had encouraged expectations of a peaceful resolution to their differences.

The apartment also contained several Purple Gang associates whose presence would soon become central to the resulting criminal prosecution.

Among those identified in accounts were Harry Keywell, Irving Milberg, and another alleged participant named Harry Fleisher.

Ray Bernstein was also present during the encounter, according to testimony that prosecutors later presented during the trial.

The gathering initially appeared consistent with the peaceful explanation that had brought the visitors to the apartment.

However, the apparent normality concealed an extraordinary difference between what the guests expected and what their hosts intended.

The subsequent shooting unfolded after Bernstein reportedly left the apartment and went toward a waiting automobile outside.

Accounts describe a car horn being used as a signal that preceded the sudden attack inside the apartment.

Armed men then opened fire on Paul, Lebowitz, and Sutker, leaving them with almost no opportunity to escape.

The victims were shot at close range, turning what had been presented as a negotiation into an execution.

Descriptions of the crime scene include scattered cartridge evidence, abandoned personal belongings, and the horrifying aftermath of gunfire.

Some historical narratives describe cigars remaining near the victims, emphasizing how abruptly the supposed peace meeting ended.

The precise number of shots and duration of the attack vary among accounts, making unnecessary numerical certainty inappropriate.

What matters beyond dispute is that three men died and the apartment became the center of a major investigation.

The killers fled, but the attack had produced a development they apparently failed to anticipate sufficiently carefully.

Sol Levine survived the encounter, leaving investigators with an eyewitness who understood relationships among the people involved.

His survival would become the crucial distinction separating this massacre from earlier killings that had frustrated Detroit authorities.

Levine initially faced an agonizing predicament because his knowledge made him potentially valuable to police and dangerous to criminals.

Cooperating with detectives could help establish responsibility for the murders, but it might also provoke violent retaliation.

Remaining silent, however, offered no guarantee that those responsible would permit a surviving witness to live peacefully.

The danger created an extraordinary conflict between criminal loyalty, personal survival, and the possibility of obtaining legal protection.

Police began questioning Levine as investigators searched for participants in the attack and attempted to reconstruct the meeting.

His account eventually connected major Purple Gang figures with the killings and transformed the direction of the investigation.

Authorities also received information that helped them locate suspects who might otherwise have escaped the city before arrest.

An anonymous tip reportedly directed investigators toward an address on Calvert Avenue where important suspects were staying.

Police subsequently arrested Ray Bernstein and Harry Keywell, bringing two central figures into custody after the apartment killings.

Irving Milberg was also apprehended, allowing prosecutors to pursue a case involving several prominent members of the organization.

Harry Fleisher, however, was not immediately captured, creating a separate problem for investigators attempting to prosecute everyone implicated.

The arrests represented a significant achievement because the Purple Gang had long cultivated an intimidating reputation among potential witnesses.

Yet apprehending suspects was only the beginning, and prosecutors still needed testimony capable of surviving courtroom scrutiny.

Levine’s position as a criminal associate made him both exceptionally important and vulnerable to challenges from defense attorneys.

His knowledge of the meeting could establish a sequence of events that outsiders had not personally witnessed.

However, his previous involvement in illegal activities offered defense lawyers opportunities to question his motives and credibility.

Prosecutors therefore needed supporting testimony and evidence that strengthened the account without depending exclusively upon personal trust.

Witnesses from the surrounding neighborhood reportedly described sounds, movements, and suspicious departures associated with the deadly incident.

Such observations could support portions of Levine’s story, although they did not necessarily establish every participant’s individual actions.

The investigation increasingly challenged the assumption that witnesses would never risk identifying people connected with the Purple Gang.

Levine’s willingness to cooperate became a pivotal factor in transforming an intimidating criminal case into a prosecutable one.

Preliminary proceedings unfolded during the weeks following the massacre, bringing the accused men before Michigan’s criminal justice system.

The courtroom proceedings attracted considerable attention because the defendants belonged to an organization widely associated with violence and intimidation.

Observers recognized that a successful prosecution could weaken a network that had repeatedly resisted serious criminal consequences.

The case also tested whether authorities could protect a witness whose testimony threatened the freedom of powerful gangsters.

Levine identified participants and described the encounter, providing the prosecution with an account of the deadly ambush.

Historical descriptions suggest he remained visibly concerned about retaliation while facing men whose associates inspired widespread public fear.

The defense challenged his reliability and disputed the prosecution’s interpretation of the events leading to the killings.

Attorneys also explored competing explanations for the murders, attempting to undermine the claim that the defendants were responsible.

Such challenges were essential within an adversarial trial because criminal convictions required evidence satisfying the applicable legal standard.

The prosecution nevertheless maintained that the violence resulted from a deliberate arrangement rather than an unexpected spontaneous confrontation.

The defendants’ alleged financial disputes with the victims supplied an explanation for the planned meeting and subsequent attack.

Their alleged participation in organizing and carrying out the ambush helped connect motive, preparation, opportunity, and criminal responsibility.

The trial began in November 1931, only weeks after the shooting had stunned Detroit’s residents and authorities.

That relatively rapid progression reflected the seriousness of the case and the importance attached to securing criminal convictions.

Levine’s testimony became a central feature, with supporting accounts helping prosecutors argue that the killings were intentional.

The defense sought to cast doubt upon his involvement and his ability to identify the actual perpetrators accurately.

Nevertheless, the jury ultimately found Ray Bernstein, Harry Keywell, and Irving Milberg guilty of first-degree murder.

All three received life sentences, an extraordinary defeat for figures associated with a previously formidable criminal organization.

The sentences removed important members from Detroit’s streets and demonstrated that the Purple Gang’s reputation could no longer guarantee immunity.

The significance extended beyond the punishment of three individuals because the outcome damaged the organization’s wider psychological authority.

Fear had helped sustain the gang’s influence, persuading competitors and witnesses that resistance might produce deadly personal consequences.

A successful prosecution demonstrated that criminal intimidation, however extensive, did not automatically prevent cooperation with law enforcement.

It also showed that violent organizations could suffer serious consequences when their own actions created motivated witnesses.

Levine’s testimony helped penetrate a culture of silence that had repeatedly complicated prosecutions involving powerful organized crime figures.

For police and prosecutors, the convictions represented a powerful example of how eyewitness cooperation could overcome intimidation.

For Detroit’s underworld, the outcome suggested that established leaders could lose their freedom despite extensive criminal connections.

However, the massacre did not instantly eliminate every Purple Gang operation or bring organized crime throughout Detroit to an end.

Criminal networks seldom disappear overnight because individual members, financial relationships, and profitable illegal markets can survive leadership losses.

The Purple Gang had already experienced internal divisions, commercial disputes, and challenges from competing organizations before September 1931.

Those problems continued afterward, accelerating the fragmentation of what had once appeared to be a remarkably powerful network.

Rival organizations increasingly competed for opportunities in gambling, liquor distribution, and other illegal commercial activities across the city.

The eventual repeal of national Prohibition also transformed the economic environment that had supported the gang’s extraordinary expansion.

When federal alcohol prohibition ended in December 1933, illegal liquor suppliers confronted a substantially different competitive landscape.

Legal alcohol businesses could increasingly serve customers previously dependent upon smugglers, undermining some traditional sources of criminal revenue.

Not every organized crime activity depended upon Prohibition, and many networks redirected their attention toward other profitable enterprises.

Nevertheless, the Purple Gang’s particular structure suffered from leadership losses, factional hostility, and the disappearance of favorable conditions.

By the middle of the 1930s, its former dominance had largely dissolved, although individual associates remained criminally active.

Other underworld organizations subsequently exercised greater influence over activities that Purple Gang members had once aggressively sought to control.

The decline therefore resulted from several interconnected developments rather than a single isolated shooting or courtroom victory.

Still, the Collingwood Manor convictions marked a decisive moment because they directly weakened the organization’s leadership and mystique.

The case also contained an important unresolved chapter involving Harry Fleisher, another man implicated in the fatal ambush.

Unlike Bernstein, Keywell, and Milberg, Fleisher avoided the initial convictions and remained outside custody for an extended period.

He eventually surrendered in 1932, creating an opportunity for prosecutors to pursue another case connected with the killings.

By then, however, the authorities faced a major problem involving the availability of their indispensable eyewitness.

Sol Levine could not be located when prosecutors sought to proceed with the case against the remaining suspect.

Without his testimony, the prosecution encountered difficulties establishing responsibility to the standard required for a criminal conviction.

The case against Fleisher was dismissed, and he was not convicted for his alleged role in the massacre.

His legal outcome illustrated the difference between historical suspicion and criminal guilt established through a successful prosecution.

Levine’s disappearance introduced another enduring mystery into a story already dominated by deception, violence, and shifting alliances.

Some accounts speculate that criminal associates may have harmed him, while others suggest he deliberately disappeared for protection.

Neither interpretation should be treated as established without reliable evidence explaining what happened to him after his testimony.

His uncertain fate also illustrates the extraordinary personal dangers faced by witnesses confronting violent organized crime networks.

Bernstein, Keywell, and Milberg remained responsible under their convictions, regardless of the unresolved questions surrounding other alleged participants.

Milberg died while imprisoned in 1938, only several years after the killings that had secured his life sentence.

Bernstein also died in prison, never regaining the freedom he lost following the Collingwood Manor murder convictions.

Keywell remained incarcerated for decades, eventually gaining release in 1995 after serving approximately sixty-four years behind bars.

He died in 1997, having spent the overwhelming majority of his adult life imprisoned for the killings.

Their differing fates demonstrate the lasting consequences of the criminal enterprise’s attempt to settle a dispute through murder.

Other Purple Gang figures survived the organization’s decline, although their individual experiences varied considerably during the following decades.

Abe Bernstein remained a historically recognizable figure, but his brother’s conviction had helped weaken their criminal network.

The decline of the organization also formed part of larger changes reshaping American organized crime during the Depression.

Criminal groups increasingly competed through different structures, alliances, and business opportunities as the Prohibition economy gradually disappeared.

The Purple Gang’s story illustrates how organizations built through intimidation can become vulnerable to their own methods of control.

Violence may frighten opponents temporarily, but repeated killings create enemies, attract investigators, and destabilize relationships among criminal partners.

The Collingwood victims were themselves underworld participants, yet their murders produced consequences far beyond their personal criminal activities.

Their deaths generated an investigation that exposed important figures and encouraged authorities to challenge an established criminal hierarchy.

Sol Levine became the crucial surviving connection between the apartment shooting and the courtroom where responsibility was established.

His testimony helped transform an otherwise familiar gangland killing into one of Detroit’s most consequential organized crime prosecutions.

The massacre remains historically significant because it revealed the limits of a criminal organization’s ability to govern through fear.

Its consequences were not confined to three murder convictions, important though those judicial outcomes undoubtedly were for Detroit.

The case damaged the Purple Gang’s image, accelerated existing weaknesses, and demonstrated how intimidation could ultimately become self-defeating.

In the years that followed, the organization lost its former position within Detroit’s fiercely competitive criminal underworld.

The exact circumstances of Levine’s disappearance remain uncertain, preserving an unresolved dimension of this exceptionally violent historical episode.

Yet the central outcome is clear: three men were murdered, and three prominent Purple Gang figures received life sentences.

A meeting intended to eliminate troublesome associates instead helped destroy the power of those who had arranged it.

That contradiction remains the defining lesson of Collingwood Manor, where a calculated act of intimidation accelerated an empire’s decline.
