Nahun Justiniano Guerrero, 21, was shot and killed on July 24, 2019, at 5184 Canoga Street in Montclair, California. He was taken to a hospital but died of his injuries; another male was wounded in the same incident and survived. Guerrero left behind his young son, Isaac Nahun Guerrero, and other family members.

Investigators arrested two Montclair residents, Manuel Corona, 27, and David Rodriguez, 26, and the Montclair Police Department identified them as responsible for the shooting. Both men were on probation for prior felony convictions in Riverside County at the time. Corona was booked on charges including murder, attempted murder, committing a crime to benefit a criminal street gang, and possession of a firearm and ammunition as a felon. Rodriguez, who was already in custody on an unrelated matter, was charged with murder, attempted murder, and committing a crime to benefit a criminal street gang.
