Fatal I-15 Crash That Killed Grandma, Toddler Under Review: DA

The accused driver is currently in custody for unrelated charges

The San Diego County District Attorney says an early morning crash on Interstate 15 that killed a grandmother and a toddler is "all under review."

Officials did not file charges against an accused drunken driver arrested for the crash at his scheduled arraignment Wednesday, which was canceled. 

A spokeswoman with the DA says the office plans to file charges, but decisions on what those charges may be have not been made. 

The accused driver is currently in custody for unrelated cases and is not eligable for bail, according to Barbara Medina with the DA's office. He will remain in custody and an arraignment date will be announced.

California Highway Patrol (CHP) officials said the deadly crash happened around 1:45 a.m. on Saturday on southbound I-15 at Scripps Poway Parkway, near Mercy Road.

Lina Nebrida, a 64-year-old grandmother, was in her family's Honda with her 35-year-old daughter, her five year old granddaughter and her two-year-old granddaughter Kiera Magat when a silver Cadillac CTS crashed into them, according to authorities. 

The driver of the Cadillac -- identified by officials as Grant Stewart Thoren, 31 -- stopped momentarily on the right shoulder of the freeway, but then fled the scene.

CHP officials said that due to the damage from the hit-and-run collision, the Honda became disabled in the traffic lanes.

Moments later, a man driving a red pickup truck, accompanied by a passenger, failed to see the disabled Honda and slammed into the vehicle. That driver remained at the scene.

When emergency crews arrived, the Honda was so mangled they had to extricate the family from inside.

Nebrida and her 2-year-old granddaughter did not survive, CHP said.

The 35-year-old woman the 5-year-old girl, who have not yet been identified, were rushed to local hospitals with major injuries. The girl suffered a concussion and is currently being treated at Rady Children's Hospital. Her mother was hospitalized but has since made progress with her recovery, according to a family spokesman.

The passenger in the red pickup truck was also taken to a local hospital with unspecified minor injuries. Officials said the driver of the truck was not injured.

Investigators launched a search for the driver of the Cadillac who fled the scene. Hours later, CHP officials confirmed Thoren had been arrested at his home in Vista on suspicion of driving under the influence, thanks to a tow truck driver.
