Isaac Anthony Espinoza was a 29-year-old San Francisco Police Department officer killed April 10, 2004 while working undercover in the Bayview District. He and his partner, Officer Barry Parker, approached a man they found suspicious when the man opened fire with an AK-47 assault rifle. Espinoza was struck multiple times and died a few hours after being taken to the hospital; Parker was wounded but survived after treatment.

The suspect, David Hill, was captured after a manhunt and later charged with murder, attempted murder and related offenses. At trial the defense said Hill mistook the plainclothes officers for gang members; the prosecution presented evidence of Hill’s gang ties and an intent to kill law enforcement. Hill was convicted of second-degree murder, attempted murder and knowingly murdering a peace officer and received consecutive life terms, one without parole.

Espinoza left a wife, a three-year-old daughter, his parents and a sister.
