RIVERSIDE: Fleeing suspect ditches handgun, later arrested

RIVERSIDE – A Riverside area transient was arrested after leading Riverside police officers first on a vehicle pursuit and then on a foot pursuit Saturday, Oct. 28. While fleeing from officers the man allegedly tossed a firearm, which was located and recovered by officers. The alleged suspect, who initially evaded arrest, was later tracked down and arrested by Riverside Police officers.

Officers were patrolling the neighborhood in the area of Grove Avenue and 14th Street at about 7:10 a.m., when they attempted to conduct a traffic stop on a vehicle. The driver, who was later identified as 37-year-old Gabriel Anthony Triviso, refused to yield and a brief pursuit ensued.

During the vehicle pursuit Triviso reportedly fled in an extremely reckless manner, without regard for the safety of other citizens or pursuing officers.

Triviso eventually fled on foot from the vehicle near Victoria Avenue. While he was running from officers Triviso reportedly discarded a firearm. Officers later located and recovered the weapon. During the foot pursuit the officers lost sight of the suspect and established a perimeter.

In spite of help from assisting officers and a department K-9 conducting a yard-to-yard search, officers were not successful in locating Triviso.

The officers who initiated the pursuit continued their investigation and later developed information regarding where Triviso had fled and was hiding.

With assistance from other officers and the department’s K-9, the original officers responded to the residence where they believed Triviso had fled. Officers surrounded a residence and quickly determined the alleged suspect was inside. After K-9 announcements were given, Triviso complied with commands to come out of the home and was safely taken into custody without further incident.

Triviso was arrested and booked into the Robert Presley Detention Center for felony reckless evading, being a felon in possession of a firearm, being a felon in possession of ammunition, and violation of Post-Release Community Supervision.

A jail records search revealed Triviso is being held in lieu of $100,000 bail and he is scheduled to be arraigned at the Riverside Hall of Justice Nov. 2.

Anyone with information about this incident or arrest is encouraged to contact Riverside police officials at (951) 354-2007. Callers can refer to incident file number P16199665 and can remain anonymous.
