Condemned inmate Anthony Delgado, 49, attacked a correctional officer with an inmate-manufactured weapon at San Quentin State Prison Thursday morning while being examined by medical staff.

Investigators at San Quentin have launched a probe into the attack that occurred just after 9 a.m. as the officer was providing coverage during a medical examination in the prison’s Adjustment Center housing unit. The Adjustment Center is one of five units in the prison where male condemned inmates are housed.

The officer suffered a significant facial injury. He was taken to an outside hospital for treatment of several lacerations and is expected to make a full recovery.

Delgado was sentenced to death in Kings County on June 21, 2000. He was convicted of the first-degree murder of California State Prison-Corcoran inmate Frank Mendoza in 1998 and the first-degree murder of inmate James Mahoney in 1999, also at California State Prison-Corcoran. Delgado has been on California’s Death Row since June 21, 2000.

Delgado was initially admitted to state prison from Monterey County in 1986 with a four-year sentence for receiving stolen property. He served a two-year sentence in 1986 from Solano County for possession/manufacture of a deadly weapon by a prisoner, an in-prison offense.

In 1990, he was admitted to state prison from Monterey County for second-degree burglary and served a three-year sentence.

In 1994, Delgado was admitted from Santa Cruz County to serve a five-year sentence for assault with a firearm.

He was sentenced in Lassen County in 1998 to serve a life sentence for resisting or deterring an officer with threat or violence and battery on a non-prisoner, in-prison offenses and his third strike.

There are 749 inmates on death row in California.
