On March 9, 2018, at approximately 9:04 P.M. Pomona Police officers responded to a call for service of a person driving recklessly. When officers arrived, they located the suspect's vehicle and attempted to conduct a traffic stop, however, the suspect failed to yield, and a vehicle pursuit ensued. During the pursuit, the suspect collided with a parked vehicle. After the traffic collision, the suspect fled on foot and a foot pursuit occurred. The suspect fled to a nearby apartment complex where he barricaded himself in a bedroom in one of the apartments. The officers attempted to contact the suspect, when the suspect began to shoot through the door fatally striking Officer Casillas.
Officer Gregg Casillas has been a dedicated member of the Pomona Police Department family since March 2015 when he was first hired as a Pomona Police Records Specialist. His honesty and maturity led to his transfer to the Pomona City Jail as a Pomona Police Jailer less than a year later in November 2015. Gregg remained committed to his goal of becoming an officer and was hired as a Pomona Police Officer Recruit in March 2017. He then graduated from the San Bernardino County Sheriff’s Academy six months later and was sworn in as a Pomona Police Officer. Gregg is survived by his wife Claudia, sons Gregorio (4 years old) and Mariano (5 months old), father Greggory Casillas, mother Marisela Casillas, and brothers Dominick and Shawn.
The Pomona Police Officers' Association feels a great loss and extends thoughts and prayers to Officer Casillas's family.
