A tragic accident on Memorial Day killed four people approximately 20 miles north of Desert Center in Riverside County, California. A witness called in to report the accident at 3:11 p.m. According to an eyewitness who spoke to the Los Angeles Times, a car was traveling southbound on the two-lane Highway 177 when it crossed over the center line, seemingly in an attempt to pass traffic. It then slammed head-on into a big rig truck. Six California Highway Patrol officers and 11 Riverside County Fire Department and Cal Fire/Riverside firefighters were sent to the scene of the Riverside truck accident.
Officers found three individuals dead at the scene. A fourth person was extricated from the car and then airlifted to Regional Medical Center in Palm Springs. He was later pronounced dead at the hospital. The crash had caused a large cloud of dust and debris to rise into the air and the spilling of diesel fuel all over the road. The eyewitness—Brian Mumey, a retired U.S. Army infantryman—said he treated the driver, who was the only person alive when he arrived. He noted that there was a group of trucks and RVs returning from Memorial Day events pulling boats, and that many cars were trying to pass them, including the car involved in the accident.
