Monserrat Colorado, 20, was shot multiple times late on June 2, 2025, on the 1500 block of Lukup Lane in Costa Mesa. Officers arriving after several 911 calls found her on a sidewalk with several apparent gunshot wounds; she received aid on scene and was taken by Costa Mesa Fire & Rescue to a local hospital, where she was pronounced dead. Investigators said the assailant was someone the victim knew. Colleagues identified Colorado as a home healthcare worker who had just finished a shift and was waiting for a ride when she was attacked.

By June 6 detectives arrested 19-year-old Oscar Saldivar of Huntington Beach on suspicion of Colorado’s murder. Prosecutors charged Saldivar with murder on June 9 and filed a sentencing enhancement for the discharge of a firearm causing death. Authorities have not publicly detailed a motive and the investigation remained ongoing.

Did anyone in the Costa Mesa area know Colorado’s routine or see her on Lukup Lane that night?
