La Mesa police and a helicopter descended on the 3700 block of Riviera Drive before dawn today after reports of possible gunshots in the residential neighborhood. Officers asked anyone who saw or heard anything suspicious to call 911 as the search unfolded.
The La Mesa Police Department announced the search in a post on its official account, stating that officers and a helicopter were searching the area for possible gunshots reported near the 3700 block of Riviera Drive. The department urged residents to dial 911 immediately if they spotted or heard anything out of the ordinary while the operation was underway. Riviera Drive sits in a suburban stretch of single-family homes near State Route 94 and Highway 125, according to the City of La Mesa.
As of this report, it remains unclear whether officers or the air crew located spent casings, property damage, or a suspect near the scene, or whether the report of gunfire will ultimately be confirmed. La Mesa police have not yet released additional details beyond the initial advisory.
Why a Helicopter, Not Just Ground Officers
La Mesa's police department does not operate its own aviation unit, so it leans on regional mutual-aid partners such as the San Diego County Sheriff's ASTREA unit or San Diego Police Department air support whenever a search calls for eyes in the sky. ASTREA, which flies out of Gillespie Field in El Cajon, has provided aerial support across San Diego County since 1971 and equips its helicopters with night-vision systems and infrared thermal technology to help ground officers spot people or evidence in the dark, per the San Diego County Sheriff's Office.
That kind of mutual-aid arrangement has shown up repeatedly in La Mesa in recent months. In February, La Mesa police and a Sheriff's ASTREA helicopter conducted a late-night airborne search in the 5500 block of Amaya Drive after a residential break-in, eventually locating a suspect hiding in nearby brush, per 619 News Media. Just weeks ago, La Mesa police and a San Diego Police Department helicopter searched the area near the 4200 block of Spring Street for a male suspect linked to an altercation, a sweep that Hoodline covered in its piece on the Spring Street helicopter search.
What Charges Could Apply If Gunfire Is Confirmed
If investigators do confirm that a firearm was discharged in the neighborhood, California law treats grossly negligent discharge of a weapon in a way that could cause injury or death as a wobbler offense under Penal Code Section 246.3, according to the Shouse Law Group. That means prosecutors could pursue the charge as either a misdemeanor carrying up to a year in county jail or a felony carrying up to three years in state prison, though the statute requires proof the firing was willful rather than accidental.
The city's police department is a relatively small operation for the volume of calls it handles: 69 sworn officers and 31 civilian staff respond to more than 100,000 calls for service annually across patrol, traffic, and investigative divisions, according to the City of La Mesa. Broader crime data from Crime Explorer shows La Mesa's violent crime rate running below the national average, even as incidents like Friday's search keep East County residents on alert.
How to Report Information or Follow Updates
La Mesa officials typically use the Nixle alert system and the department's social media channels to keep residents informed during active searches, directing people toward 911 for emergencies and non-emergency lines for tips. Residents with information about the Riviera Drive incident can call the city's 24-hour non-emergency line at 619-667-1400, or reach San Diego County Crime Stoppers anonymously at 888-580-TIPS.
Friday's search adds to a string of recent La Mesa police operations that have drawn helicopter support, including sweeps near Lake Park in February and a downtown intersection response in March. No further details on the Riviera Drive investigation, including whether the gunfire report was substantiated, had been released as of publication.
