SUMMARY: On Sunday, April 20, 2025, at about 4:17 p.m., Fontana Station deputies responded to a report of gunshots heard in the 17000 block of Gray Pine Place, unincorporated San Bernardino, near a residential housing track known as Rosena Ranch. The reporting party reported a black off highway vehicle drove up an open hillside and gunshots were heard shortly thereafter. An additional reporting party reported similar information and, when the first deputy arrived, they also heard multiple gunshots coming from the area directly north of the residences.

With the assistance of Sheriff’s Aviation, Angel Flores, a 20-year-old male resident of San Bernardino, Kenner Garrido, a 19-year-old male resident of Rialto, and Denisse Castillo, a 19-year-old female resident of Rialto, were contacted and detained. A handgun and evidence of shooting were located at the scene. There were no injuries or victims located. All three suspects were arrested and later issued citations for negligently discharging a firearm.
