William O'Neal
FBI Informant and Agent Provocateur (1968-1969)
FBI informant who infiltrated the Black Panther Party and facilitated the assassination of Fred Hampton
Overview
William O'Neal was an FBI informant who infiltrated the Illinois chapter of the Black Panther Party under COINTELPRO and provided the intelligence that enabled the Chicago Police raid on December 4, 1969, which killed 21-year-old Chairman Fred Hampton and 22-year-old Mark Clark. Recruited at age 17 after an arrest for car theft and impersonating a federal officer, O'Neal rose to become Hampton's personal bodyguard and head of security for the Illinois chapter while secretly reporting to FBI Special Agent Roy Mitchell. He provided the floor plan of Hampton's apartment that was used to plan the raid and allegedly drugged Hampton with secobarbital the night before, ensuring he could not resist. O'Neal received a cash bonus from the FBI after the raid. He was placed in the federal witness protection program but ultimately took his own life in 1990, shortly after giving a filmed interview for the documentary "Eyes on the Prize II" in which he displayed visible distress when discussing his role.

HAMPTON FLOOR PLAN: Provided a detailed floor plan of Fred Hampton's apartment at 2337 W. Monroe Street to his FBI handler, which was forwarded to the Cook County State's Attorney's office and used to plan the December 4, 1969 pre-dawn raid.
DRUGGING HAMPTON: Alleged to have put secobarbital (a barbiturate) in Fred Hampton's Kool-Aid drink on the evening of December 3, 1969, ensuring Hampton was unconscious and unable to respond when 14 officers entered his apartment at 4:45 AM.
THE RAID: The December 4, 1969 raid killed Fred Hampton (shot twice in the head at close range while unconscious in bed) and Mark Clark. Forensic evidence showed police fired 82-99 shots; at most one shot came from a Panther. O'Neal was not present during the raid.
