O'Farrell was murdered in a bar fight in 1989 shortly before he was due to start serving a prison sentence for conspiring to bomb the clubhouse of a rival motorcycle gang, the Outlaws.

[5] Christie described O'Farrell in his book Exile on Front Street: My Life as a Hells Angel as "a tough-as-nails outlaw, ruggedly handsome with long, thick brown hair and sad, soulful eyes that made him a favorite with women.

[16] O'Farrell, Barger and eight other Hells Angels from California and Alaska were extradited to Louisville, Kentucky, to face trial for conspiring to transport firearms and explosives across state lines in order to kill members of the Outlaws Motorcycle Club in retaliation for the death of John Cleave Webb, the Anchorage HAMC chapter president who was shot and killed by two Outlaws members outside a biker bar in Jefferson County, Kentucky, on August 12, 1986.

[18] While awaiting sentencing, the pair attended the funeral of San Bernardino Hells Angels chapter sergeant-at-arms Aristeo Andres "Art" Carbajal, which was held in Bloomington on February 21, 1989.

[22] Two weeks before he was due to report to United States Penitentiary, Atlanta to begin serving his sentence, O'Farrell was drinking at the Halfway Club in San Leandro, California, on June 6, 1989, when he was recognized by a member of the Aryan Brotherhood as the man who had attempted to collect a drug debt from him two months prior.

[25] O'Farrell was laid to rest at Evergreen Cemetery after approximately a thousand people, including his wife Teddy and son, attended his funeral in East Oakland on June 11, 1989.

[26] Two Aryan Brotherhood members charged in connection with O'Farrell's death, Aaron "Jerry" Marsh and Michael Bruce "Tank" Shepherd, were arrested in the following weeks.

Marsh – who was accused of firing several shots during the fight, including one that wounded Musick – was taken into custody in Manteca on June 27, 1989, and Shepherd – who was charged with the homicide of O'Farrell – was apprehended by San Bernardino County Sheriff's Department deputies and California Highway Patrol troopers on Route 60 on July 26, 1989, after a high-speed chase through Chino and Ontario.

[27] Marsh was strangled to death in Pelican Bay State Prison on July 25, 1997, by cellmate Gary J. Littrell after refusing an order from the Aryan Brotherhood leadership to murder another inmate.
