Greggory Casillas, V

Police Officer Gregg Casillas was shot and killed as he attempted to arrest a man in the 1400 block of South Palomares Street following a vehicle pursuit.

The vehicle fled after officers attempted to stop it for reckless driving. The driver crashed into another vehicle before fleeing on foot and entering an apartment. As Officer Casillas and another officer attempted to make contact with the man he fired through the apartment door, striking both officers.

The officers were both transported to a local hospital where Officer Casillas succumbed to his wounds. The man surrendered after remaining barricaded inside his home for more than 15 hours. He was charged with Officer Casillas' murder as well as several counts of attempted murder of a peace officer.

Officer Casillas had served with the Pomona Police Department for six months and was still in field training at the time of the incident. He had been employed as a civilian with the agency for three years before entering the police academy. He is survived by his wife and two children.

In August 2018, I-10 between North San Antonio and Mountain Avenues was renamed Pomona Officer Greggory Casillas Memorial Highway.

Three years ago today you lost your life. On March 11,2018 my godmother received a liver transplant. I’m not positive but I do believe that it was your family’s compassionate donation of your organs that saved my godmothers life. Today I was not looking for your memorial page, your memorial page found me and it found me today, the anniversary of your untimely passing. The same “coincidence” happened two years ago. I’m sorry your life was cut short. I pray for your wife and children. I hope that you are still with them, watching over them. And if by chance you were the donor of my godmothers liver, thank you for saving her.
I will never forget when her surgery was over the doctor came to talk to our family in the waiting room. He said “the liver started working right away” and “she got a very special liver”.
RIP Officer Casillas
