Martin Diaz, 48, was found dead in his Baldwin Park, California, home on November 25, 2015, the victim of multiple gunshot wounds. Authorities treated the scene as a homicide investigation after evidence of forced entry and other factors led detectives to conclude the shooting was a targeted attack.

Investigators identified several suspects and arrested a 23-year-old male who was described as having a direct connection to Diaz. That suspect was charged with first-degree murder and, after a trial featuring forensic evidence and witness testimony, was convicted and sentenced to life in prison without the possibility of parole.

Diaz’s death prompted vigils and memorials and prompted local discussion about violence and public safety. If anyone knew Martin Diaz, his movements in the days before November 25, 2015, or has information that wasn’t already shared with investigators, please come forward.
