A man connected to the fatal "San Quentin 6" prison escape attempt of 1971 was killed by fellow inmates in Sacramento, Calif., according to corrections officials.
Hugo Pinell, 71, was attacked in an exercise yard. After the attack, other inmates soon joined in, causing a massive 70-inmate uprising composed of gangs and makeshift weapons, according to MSN.com.
Dana Simas, corrections spokesperson, said that Pinell was "definitely" targeted by a fellow inmate.
Officers had to use warning shots and pepper spray to subdue the uprising.
No corrections officers were injured, but 11 inmates had serious enough injuries that they needed to be taken to off-site medical facilities, according to USA Today.
Pinell's involvment in the escape attempt 40 years ago involved slitting the throats of San Quentin prison guards. The attempt resulted in the death of three guards, two inmate trustees and escaped ringleader George Jackson.
Urbano Rubiaco Jr., a correctional officer who survived the 1971 escape attempt, later testified that Pinell used a homemade knife made of a toothbrush handle and razor blades to cut his neck.
"He said 'I love you pigs,' and then he cut my throat," said Rubiaco.
Pinell was serving three life sentences before he was killed, for crimes of rape, murder and attempted escape, according to FOX News.
