Police Officer Shaun Diamond succumbed to a gunshot wound sustained the previous day as he and members of the Pomona SWAT team attempted to serve a search warrant.

Officer Diamond was the breach officer as the team attempted to make entry into the home in the 100 block of San Marino Avenue in San Gabriel. As they breached the storm door the subject inside opened the main door and fired a single shot from a shotgun, striking Officer Diamond in the back of the neck. The shot also wounded the subject's father in the arm.

Other officers immediately pulled Officer Diamond to a safe location and he was transported to Huntington Memorial Hospital in Pasadena, where he died early the following morning.

The subject was taken into custody at the scene and charged with murder of a police officer with special circumstances.

Officer Diamond had served with the Pomona Police Department for eight years and had previously served with the Los Angeles Police Department and the Montebello Police Department. He is survived by his son, daughter, and parents.

In February 2015, Downtown Plaza was renamed to Diamond Plaza with unanimous support. In October 2016, I-10 between 57 Freeway and Towne Avenue was renamed Pomona Police Officer Shaun Diamond Memorial Highway.

I wanted to take a moment and thank you Officer Diamond for your 16 years of service here in LA County where you made it a better place by policing the cities of Los Angeles, Montebello, and Pomona. I am a recruit for LASD and wanted to say I admire your dedication and I wish to one day become half the person you were. I am sure you made an impact in many people's lives. I heard about a homeless man that lived in Pomona and stated he always felt safe during the nights because of Police Officers like yourself. Thank you and your family for the support they gave you to become the person you were
