SANTA ANA, Calif. — A convicted drunken driver has been arrested on murder charges for a July crash in Southern California that killed three people.

Jeremy Greenwood of Rialto was arrested Wednesday. He remains jailed and it’s unclear whether he has a lawyer.

Prosecutors say Greenwood was drunk and doing 86 mph when his car ran a red light in Irvine in July and struck another car.

The driver of the second car and two passengers died. A third passenger in that car suffered a traumatic brain injury.

Authorities say Greenwood had a 2012 Los Angeles conviction for driving under the influence.

If convicted, he’s facing up to 51 years to life in prison.
