Philadelphia's 39th District: Inside a Notorious Police Corruption Scandal
How federal investigators uncovered systematic brutality and corruption among officers in one of America's most troubled police departments
Published June 6, 2025

Quick Facts
In the mid-1990s, the Philadelphia Police Department's 39th District became the center of one of the most significant police corruption scandals in American law enforcement history. What began with investigations into individual officers in the early 1990s exploded into a nationwide story by 1997, ultimately implicating hundreds of people and exposing systemic problems that had plagued the department for decades.
The 39th District, located in North Philadelphia, had long carried a notorious reputation. According to The Washington Post, the district's troubled history extended back years, particularly during the tenure of former Police Commissioner Frank Rizzo, when allegations of brutality and misconduct were commonplace. By the 1990s, that reputation would be thoroughly vindicated by federal investigation.
At the heart of the scandal was a group of officers that became known informally as the "Four Horsemen of the Apocalypse"—a nickname reflecting their feared status in North Philadelphia for acts of brutality and corruption. These officers operated with apparent impunity until federal investigators began turning insiders.
Timeline
Corruption in the 39th District begins, documented
Officers in Philadelphia's 39th District begin the period of systematic abuse that is primarily documented from 1988. Some sources indicate activities as early as 1987.
Arthur Colbert files complaint against officer John Baird
Citizen Arthur Colbert files a complaint in 1991 against officer John Baird for assault. The complaint contributes to triggering the subsequent federal investigation.
Scandal becomes publicly known
Federal investigations and guilty pleas bring the 39th District corruption to public knowledge in 1995. The case draws national attention in the US.
Appeal ruling: United States v. Baird, 109 F.3d 856
The federal appeals court for the Third Circuit issues a ruling in United States v. Baird, 109 F.3d 856 (3d Cir. 1997), affirming the appeal proceedings for officer John Baird.
At least five officers convicted; 160–300 cases overturned
By mid-1997, at least five officers have been convicted in federal courts. Human Rights Watch documents that between 160 and 300 cases have been overturned, while thousands are under review.
The breakthrough came through cooperation. Officer Thomas Ryan, working with federal investigators, became a crucial witness. Ryan provided federal agents with an informant—Pamela Jenkins, who was also his lover—and both wore body wires to record incriminating conversations with fellow officers. These recordings would become pivotal evidence in the investigation.
On a December 1994 night, Detective Dambach and Agent Williamson confronted another officer, Baird, with the evidence they had gathered from Ryan and Jenkins's recordings. The confrontation put Baird in an impossible position: cooperate or face exposure. Initially, Baird agreed to cooperate, but his resolve wavered. He later lied to a federal agent to protect the officers under investigation, a decision that cost him dearly. Baird was charged and ultimately pled guilty to obstruction of justice.
The investigation didn't stop at the 39th District. Federal authorities discovered similar patterns of corruption and brutality extending into the Philadelphia Police Department's elite Highway Patrol Unit. Officer James Ryan (unrelated to Thomas Ryan) came forward to cooperate against officers in the Highway Patrol Unit engaged in comparable misconduct, broadening the scope of the federal investigation significantly.
The scale of the corruption shocked observers. Human Rights Watch, the international human rights organization, conducted its own investigation and concluded that the Philadelphia Police Department had developed one of the worst reputations for corruption and brutality among major American police departments. The HRW findings underscored that the 39th District scandal was not an isolated incident but rather a reflection of deeper systemic problems.
The scandal also intersected with other controversial cases in Philadelphia law enforcement history. Some individuals involved in the 39th District corruption scandal were linked to legal proceedings surrounding the 1981 murder of Officer Daniel Faulkner, a case that resulted in the conviction of Mumia Abu-Jamal and remains disputed by many observers.
The 39th District corruption scandal represented a critical moment in Philadelphia's policing history. Federal investigations, insider cooperation, and documented evidence exposed the extent to which brutality and corruption had become embedded in certain units of the department. While some officers faced justice, the scandal raised broader questions about accountability, training, and oversight within major American police departments that continue to resonate today.
