Elmer Jonathan Diaz

Police Officer Jonathan Diaz was shot and killed while intervening in a domestic violence incident while off duty.

He was attending a birthday party at a home on Eddy Street, near Carolyn Avenue, in Hanford when another partygoer was violently assaulted by her boyfriend. Officer Diaz was able to move the woman outside to safety and then returned into the home to de-escalate the incident.

The subject who assaulted the woman was an investigator for another local agency. As Officer Diaz re-entered the home the man opened fire, killing Officer Diaz and wounding his own father. The subject then killed himself.

Officer Diaz had served with the Lemoore Police Department for three years and had previously served with the Huron Police Department for three years. He is survived by three children, parents, and three siblings.

Officer Diaz was the recipient of his agency's 2018 Officer of the Year award.

Officer Diaz, I never had the pleasure of meeting you, however my family has met your beautiful family. Your family misses you very much and are extremely proud of you. Their hearts are broken yet they are so caring and considerate of other families that have also lost an Officer in the line of duty. Our families have gotten to know each other and we are honored to know you through them. You were a great officer and an even better human being. Rest in peace brave warrior and may you be in heaven in the company of our Lord Jesus Christ.
