1 dead, 1 hospitalized in crash with DUI driver that caused big rig to overturn on 60 Freeway in Pomona

A person was killed and another was hospitalized after a crash with an alleged DUI driver that caused a semi truck to overturn on the 60 Freeway in Pomona late Friday. 

The crash happened at around 10:30 p.m. on eastbound lanes of SR-60 near the SR-71 connector, according to the California Highway Patrol. They arrived to find two damaged big rigs and a Mercedes-Benz GLC 300 SUV that were involved in a collision. 

Investigators determined that the Mercedes, which was being driven by 32-year-old Chino man Guadalupe Mercado, veered onto the right shoulder while driving recklessly and collided with the rear trailer of a parked big rig at the location. 

The crash then caused the SUV to ricochet back into traffic lanes where he collided with another semi truck that was driving. 

The passenger of the Mercedes, since identified as 36-year-old Andres Mercado, died from blunt force traumatic injuries suffered in the collision. His relationship to the driver remains unknown. 

Officers say that the driver suffered major injuries as well. He was rushed to a nearby hospital for treatment before being arrested on suspicion of vehicular manslaughter and felony driving under the influence. 

Al lanes were blocked by the investigation for hours, reopening just before 3 a.m. Saturday, CHP announced.

CHP officers say that another car may have been speeding or driving recklessly before they hit the semi truck. 

The truck driver was hospitalized for injuries suffered in the crash. Another person was declared dead at the scene, according to the CHP.
