Deputies from the Moreno Valley Sheriff’s Station, along with Cal Fire – Riverside and other emergency personnel, were dispatched to the scene around 4:52 p.m. after receiving reports of a major-injury traffic collision with possible entrapment, Riverside Sheriff’s Sergeant Chad Craig has since said of the accident and subsequent arrest.

When officials arrived they found two involved vehicles, described as a black, Dodge Ram truck and a gold, Toyota Solana sedan. 

Firefighters confirmed finding the driver of the Toyota trapped, critically injured, and unresponsive inside her wrecked vehicle and began a cut and rescue operation. 

After being freed from the Toyota, the victim was rushed to Riverside University Health System in Moreno Valley where despite lifesaving efforts she succumbed to their injuries and passed away.

The Riverside County Sheriff – Coroner’s Office has since identified Maria Mejia, 58, of Moreno Valley, as the driver killed in the collision. A Coroner’s release indicated she was pronounced deceased at 5:25 p.m.

Based on the circumstances, members of the Moreno Valley Station’s Traffic Collision Reconstruction Team responded to the scene and assumed the investigation.

During their subsequent investigation, officials determined that just before the collision the Dodge had been traveling northbound on Indian Street, while the Toyota had been traveling westbound on Delphinium Avenue.

“As both vehicles entered the intersection, the front of the Dodge collided into the driver’s side of the Toyota,” Craig explained. “The impact of the collision caused the Toyota to careen across the roadway and come to rest north of the intersection.”

Craig did not specify which of the two vehicles is suspected of having caused the deadly crash.

While interviewing the driver of the Dodge, since identified as 28-year-old Juan Daniel De Paz Guadarrama, Traffic Team deputies determined he was under the influence of alcohol and arrested him at the scene.

He was later booked into the Robert Presley Detention Center in Riverside on suspicion of driving under the influence resulting in bodily injury.

Online jail records indicate he remains in custody, where he is being held in lieu of $50,000 bail or bond. He is scheduled to be arraigned at the Riverside Hall of Justice on March 2.

While officials worked at the scene they called for the temporary closure of the intersection, but the roadway has since been reopened.
