At 10:35 a.m. on July 26, 2010, inmate Edward John Schaefer, 44, was stabbed in the chest and neck with an inmate-made weapon. He was taken by ambulance to an outside medical facility where he was pronounced dead at 9:03 p.m. Monday.
Schaefer was received from Marin County on July 16, 2010 with a 24-years-to-life sentence for second-degree murder and gross vehicular manslaughter while intoxicated. In 2005, Schaefer served a four-year sentence from Marin County for corporal injury to a spouse.
The incident is being investigated as a homicide by the prison’s Investigative Services Unit. Prison investigators have identified inmate Frank Anthony Souza, 31, as the primary suspect. Investigators are looking into whether other inmates were involved.
Inmate Souza was received from Santa Clara County on Jan. 12, 2010 with a 60-years-to-life sentence for first-degree murder. Souza has three prior commitments: in 1998, he served a one-year, six-month sentence from Santa Clara County for grand theft; in 1999, he served a two-year sentence for receiving stolen property; and in 2002 he served a four-year sentence from Santa Clara County for threatening a prosecution witness with force and violence.
The Marin County District Attorney’s Office has been contacted and the Office of the Inspector General’s Bureau of Independent Review was also notified of the incident.
Open since 1852, San Quentin State Prison is California’s oldest prison. It houses 5,027 inmates and employs 2,236 people. San Quentin includes a reception center for new commitments and parole violators, general population units, a minimum-security work crew unit, and units housing male condemned inmates.
