Handoyo "Trip" Triputra

Handoyo “Trip” Triputra was a Deputy Sheriff with the Riverside County Sheriff’s Department. “Trip” was hired in April of 2001, and was a dedicated Peace Officer who loved his job, and the community he served. “Trip” also loved his fellow brothers and sisters in the law enforcement community, and the camaraderie they shared.  After working patrol at the Riverside County Sheriff’s-Jurupa Valley Station, “Trip” held positions with: The Moreno Valley Station-Special Enforcement Team/Gang Unit, The Riverside County Regional Gang Task Force, and worked as a Task Force Officer for the Drug Enforcement Administration’s HIDTA 50 Team.


“Trip” became ill in 2011, and was medically retired from the Sheriff’s Department in November of 2012. “Trip” passed away from complications of Cerebellar Ataxia on May 13, 2019. This memorial fund was established by “Trip’s” family, along with RCGIA, in order to assist injured officers, families of fallen officers, and keep our community safe.

On behalf of RCGIA, a $500 scholarship will be given out each year on Trip's EOW (May 13). More details of the scholarship will be posted.
