on October 6, 1972; several members were involved in the murder, which hit the headlines. Member Jean Hobson had been romantically linked to federal prison inmate Ronald Beaty, who was incarcerated at Chino Prison. She and other Venceremos members made a plan to gain Beaty's escape. According to police and Beaty, who became the prosecution's star witness, two unarmed prison guards were taking Beaty to a court appearance in San Bernardino when their vehicle was ambushed near Chino. Beaty was freed when Venceremos member, 23-year-old Robert Seabok, shot both guards at point blank range, killing Jesus Sanchez and wounding his partner George Fitzgerald. After the police captured Beaty and Hobson nearly a month later, Beaty named Venceremos members Hobson, Seabok, Andrea Holman Burt, and Benton Burt as the perpetrators of the fatal assault on the prison guards. Former professor H. Bruce Franklin, four Venceremos members, and three Arizona residents were arrested in this case in late December 1972. A total of fourteen people were arrested; twelve were charged either with murder or, as was Franklin, with harboring Beaty, classified as a federal fugitive. While charges were dropped against some, the chief perpetrators were tried. Jean Hobson, 19 year-old Andrea Holman Burt, and her husband 31-year-old Douglas Burt were all convicted of second-degree murder in 1973 and 1974. Seabok was convicted of first-degree murder and sentenced to life imprisonment. Beaty had become a prosecution witness; he pleaded guilty for being part of Sanchez's death and was sentenced to life as well. By September 1973 Venceremos had officially disbanded. Some members went on to other leftist groups, such as Joe Remiro, who joined the small Symbionese Liberation Army in its early days. Aftermath Venceremos disintegrated under the duress of legal troubles, recriminations over the Beaty incident, and general factionalism. By September 1973 it had ceased to function as an organization. Robert Seabok was convicted of first degree murder; while Jean Hobson, Andrea Holman Burt, and Benton Burt were convicted of second degree murder. In March 1973, far-left militant Donald DeFreeze escaped from Soledad Prison and made his way to Oakland. He found shelter with members or associates of Venceremos at the Peking House commune, but members were concerned about police surveillance. They moved DeFreeze to a lower-profile location east of the hills in Concord. Calling himself General Field Marshal Cinque, he co-founded the Symbionese Liberation Army with Patricia Soltysik, a white woman,
