5:30 p.m. UPDATE: The California Department of Corrections and Rehabilitation has identified the stabbing victim in Wednesday’s riot as Hugo Pinell, 71.

Pinell first was sentenced to life with parole for rape with force in 1965. Six years later, he killed a correctional officer, earning him another life sentence.

He was also one of the San Quentin Six a group involved in a 1971 San Quentin Prison escape attempt that left six people dead. He was convicted of assualting two correction officers, earning him another life sentence. Guards said at the time that Pinell lured one of the guards killed in the escape by telling him he had a letter that needed mailed.

Pinell was last up for parole in 2009, but he was denied for a ninth time. In his previous attempts, the next wait would only be one to five years, but California voters passed Proposition 9, known as Marsy’s Law in 2008, which allowed the parole board to set his date for 2024.

“He was definitely the target,” California Department of Corrections and Rehabilitation spokeswoman Dana Simas said. She would not give more information about the alleged attacker for his own protection.
