Riverside County Deputy's Grappler Device Fails to Stop Fleeing Cadillac After Hour-Long Chase

A Riverside County Sheriff's deputy deployed a grappler bumper device on a fleeing white Cadillac CT5 on Bellegrave Avenue in Jurupa Valley, but the nylon-net system failed to attach, sending the car spinning across multiple traffic lanes before it crashed through a concrete wall behind a home on Antigua Drive. The suspect was pronounced dead after a lengthy standoff that drew SWAT, crisis negotiators, and dozens of deputies from two counties.

The pursuit began shortly after 2 p.m. on April 8 when deputies spotted a wanted suspect driving the Cadillac near Pats Ranch Road and Limonite Avenue in Riverside. The driver fled a traffic stop, and deputies later received information he was believed to be armed with a handgun. Over nearly an hour, the chase crossed Riverside and San Bernardino counties along the Pomona (60) Freeway and Interstate 15 before the driver exited onto Bellegrave Avenue heading eastbound.

The suspect paused at Bellegrave Avenue and Etiwanda Avenue, directly outside Jurupa Valley High School, where he sat for several minutes with deputies surrounding the vehicle before fleeing again and running over a spike strip. Seconds later, a deputy closed in and deployed the grappler near Wineville Avenue. The device, designed to shoot a nylon net from a pursuing vehicle's front bumper and wrap it around the fleeing car's rear axle, did not successfully attach to the CT5.

The Cadillac spun through multiple lanes and crashed through a concrete wall, leaving the front end heavily damaged and the windshield shattered. A man who had been in his yard heard sirens and looked over the wall just as the car approached. "All of a sudden, I see a white car start coming down the street like really fast," he told reporters. "And then they did their maneuver, and I see it coming at the wall, and I ran away from the wall as fast as I could." The deputy's vehicle also lost control during the deployment but did not crash. Aerial footage from AIR7 showed the driver moving toward the back seat after the collision; the Riverside Sheriff's Crisis Negotiation Team, a drone unit, and SWAT worked the scene before the suspect was pulled from the vehicle and pronounced dead.

The failed deployment casts a sharp light on a tool that California law enforcement has only recently embraced. Invented in 2016 by Leonard Stock of Arizona, the Grappler Police Bumper was first adopted by U.S. Border Patrol in 2018 and has since been installed on nearly 1,000 law enforcement vehicles nationwide at approximately $5,000 per unit. The Riverside County Sheriff's Department was the first agency in California to use it, beginning testing in March 2025. As of March 2026, the department had deployed the device 40 times, with 10 units in service and a goal of equipping 16 K-9 officers by July 2026. Lt. Jason Santistevan of the Special Enforcement Bureau noted the grappler has also been deployed proactively on vehicles belonging to homicide suspects, to prevent pursuits from starting in the first place.

The broader stakes are documented in grim detail. A study in JAMA Network Open recorded 3,004 fatal police pursuits in the United States from 2017 to 2021, and separate research covering 2014 to 2018 found that more than half of the 2,005 people killed in pursuit-related crashes were not the person behind the wheel of the fleeing vehicle. California leads all states in bystander pursuit deaths. The U.S. Congress has tasked the Police Executive Research Forum with drafting pursuit policy recommendations for all law enforcement agencies, a mandate that will extend to scrutinizing immobilization devices and the oversight frameworks governing when their deployment is authorized and what accountability follows when the technology fails.
