A 66-year-old inmate at San Quentin State Prison in California was found dead Wednesday, and authorities believe a 28-year-old fellow inmate may be responsible.
The body of John Sullivan, who had been convicted of failing to register as a sex offender, and was serving a 10-year sentence, was found unresponsive around 12:40 a.m. He was declared dead soon after, the California Department of Corrections and Rehabilitation told the East Bay Times.
