The Fred Hampton assassination was the December 4, 1969, killing of the 21-year-old Illinois Black Panther Party deputy chairman during a predawn raid on his Chicago apartment by officers from the Cook County State’s Attorney’s tactical unit, planned using a hand-drawn floor plan supplied by an FBI informant inside the Panthers. Hampton, drugged with a barbiturate earlier that night, never woke up. A federal grand jury later found that police fired roughly 99 shots and the apartment’s occupants fired one. A 13-year civil rights lawsuit ended in 1982 with a $1.85 million settlement paid in equal shares by the federal government, Cook County, and the City of Chicago.1Monthly Review.

Who Fred Hampton Was and Why the FBI Targeted Him
Hampton was born on August 30, 1948, in a suburb of Chicago. He joined the Panthers’ Chicago chapter in November 1968 and, at 20, became deputy chairman of the Illinois chapter.2National Archives. Fred Hampton (August 30, 1948 – December 4, 1969) He ran a Free Breakfast Program for children and pushed for community oversight of police.
In 1969 he built what he called the Rainbow Coalition, an alliance of the Black Panthers, the Puerto Rican Young Lords, and the Young Patriots Organization, a group of poor white Appalachian migrants on Chicago’s North Side. That cross-racial organizing is what put him at the top of the FBI’s list.
The Bureau had been running COINTELPRO, its Counterintelligence Program, since the late 1950s. By the late 1960s its stated aim included preventing the rise of a Black leader who could “unify and electrify” the movement, and field offices were directed to “expose, disrupt, misdirect, discredit and otherwise neutralize” Black organizations. Between 1967 and 1971 the Bureau pursued 379 proposed actions against Black nationalist targets.
The Informant and the Floor Plan
The FBI’s Chicago field office ran an informant inside the Illinois Panthers named William O’Neal. He had been recruited after an arrest for interstate car theft and impersonating a federal officer, and he rose to chief of security for the chapter. O’Neal gave the Bureau a detailed, hand-drawn floor plan of Hampton’s apartment at 2337 West Monroe Street with the location of Hampton’s bed marked. The FBI passed that plan to the Cook County State’s Attorney’s Office, which planned and carried out the raid.
Evidence developed later showed that O’Neal had slipped Hampton a heavy dose of secobarbital in a glass of Kool-Aid earlier in the evening. A criminal associate testified under oath that O’Neal had admitted to the drugging, and Cook County chemist Dr. Eleanor Berman found an unusually high concentration of barbiturates in Hampton’s blood, consistent with someone unable to wake or respond.
After the raid, the Chicago field office sent a memo to FBI headquarters requesting a $300 bonus for O’Neal, calling his intelligence of “tremendous value.” Headquarters approved it.
What Happened Inside the Apartment on December 4, 1969
At about 4:45 a.m., fourteen officers from the Cook County State’s Attorney’s tactical unit, with Chicago Police Department support, entered the apartment carrying a .45-caliber submachine gun, shotguns, and handguns. Mark Clark, a downstate Illinois Panther leader sitting in a front room with a shotgun on his lap, was shot and killed almost immediately. The single shot attributed to anyone in the apartment came from Clark’s weapon and was determined to be a reflexive discharge as he was hit.
Hampton was asleep in a back bedroom next to his fiancée, Deborah Johnson, who was nine months pregnant. Survivors testified that after the initial gunfire, officers entered the bedroom, confirmed Hampton was still barely alive, and fired two shots into his head at point-blank range. He never fired a weapon and, by all accounts, never regained consciousness.1Monthly Review. The Assassination of Fred Hampton by the FBI and Chicago Police, Forty Years Later
How the Official Shootout Story Collapsed
Cook County State’s Attorney Edward Hanrahan held a press conference describing a fierce gun battle and praising his officers’ restraint under heavy fire. The seven surviving Panthers were indicted on charges of attempted murder.3The New York Times. 7 Panthers Cited by Chicago Jury A special coroner’s jury ruled both deaths justifiable.
The story fell apart because the scene was never secured. Within hours, Panther members, independent investigators, journalists, and lawyers were inside the apartment documenting the physical evidence. Bullet holes ran from outside in, concentrated around Hampton’s bedroom. Photographs of the scene circulated widely.
The attempted murder charges collapsed once ballistics made clear there had been no shootout. A federal grand jury convened in May 1970 confirmed that police fired the vast majority of shots and that the supposed armed resistance was a fabrication.
The Criminal Case Against Hanrahan
Hanrahan and thirteen co-defendants were later charged with conspiring to obstruct justice. Prosecutors alleged that his office had thwarted investigation of the officers involved, hampered the surviving Panthers’ legal defense, and presented fabricated evidence and false accounts. On October 25, 1972, Judge Philip Romiti acquitted all fourteen, ruling that the evidence was “simply not sufficient to establish or prove any conspiracy.” Hanrahan, once considered a rising figure in Chicago Democratic politics, lost his reelection bid shortly after.
The Civil Rights Lawsuit and 1982 Settlement
The families of Hampton and Clark, along with the seven survivors, filed a $47.7 million civil rights lawsuit naming the City of Chicago, Cook County, the federal government, and 31 individual defendants, including Hanrahan and FBI agents.4The New York Times. Long-Delayed Chicago Civil Suit On Black Panther Raid Is Begun The suit alleged a coordinated conspiracy to violate the Panthers’ civil rights and cover it up.
The trial court initially directed verdicts for the defendants. The U.S. Court of Appeals for the Seventh Circuit reversed and ordered a new trial, holding that the plaintiffs were entitled to have their claims heard.5Legal Information Institute. Edward V. Hanrahan et al. v. Iberia Hampton et al. The appeals court also ordered disclosure of the FBI informant’s identity and directed the lower court to consider sanctions against defendants who had obstructed discovery.
Rather than face a second trial with the full scope of FBI involvement on the record, the parties settled in 1982 for $1.85 million. The federal government, Cook County, and the City of Chicago each paid an equal share to the nine plaintiffs. The dollar amount was a fraction of the original demand, but the split among three levels of government was itself an implicit acknowledgment that the raid and its aftermath could not withstand scrutiny.
What the Case Exposed About the FBI
The Hampton raid was not isolated. In 1975 the Senate Select Committee to Study Governmental Operations with Respect to Intelligence Activities, known as the Church Committee, held public hearings on decades of FBI domestic surveillance. The committee found that the Bureau had accumulated files on lawful activity by law-abiding citizens, used “dangerous and unsavory techniques which gave rise to the risk of death,” and targeted Black nationalist organizations with particular intensity.6U.S. Department of Justice Office of the Inspector General. The Federal Bureau of Investigation’s Compliance with the Attorney General’s Investigative Guidelines
The committee concluded that COINTELPRO’s methods were not justified by any legitimate law enforcement purpose. In response, Attorney General Edward Levi issued the first-ever guidelines governing FBI domestic intelligence investigations in 1976. Before that, the Bureau had operated without a general statutory charter for domestic surveillance, relying on internal policy that gave field offices wide discretion. The Levi guidelines set restrictions on when and how the FBI could open investigations into domestic organizations, a direct consequence of the abuses the Hampton case helped bring to light.
What Happened to William O’Neal
Once his role as an informant became public through the civil litigation, O’Neal entered the federal witness protection program under the alias William Hart and relocated to California. He returned quietly to Chicago in 1984. He later gave an on-camera interview for a documentary, alternating between defending his actions and expressing remorse. On January 15, 1990, the night the documentary aired, the 40-year-old O’Neal ran from his uncle’s apartment into traffic on the Eisenhower Expressway and was struck and killed by a car. His death was ruled a suicide.
