The L.A. County District Attorney filed charges Tuesday against 41-year-old suspect Anthony Craig Chambers for the fatal shooting of 51-year-old Metro bus driver Alan Thomas.
Thomas had just steered the bus onto Santa Monica Boulevard out of a layover area at La Cienega Boulevard when he was attacked on Sunday morning.
Shortly after boarding around 9 a.m., the defendant allegedly pulled a shotgun from a suitcase, approached the victim and shot him twice, according to the D.A.'s news release.
Chambers was arrested near the scene. Thomas was taken to Cedars Sinai Medical Center where he died around 9:30 a.m.
For lying in wait, Chambers was charged Tuesday with special circumstance murder. He was also charged with murder of transportation personnel, and there was a special allegation of personal use of a firearm.
Prosecutors have not yet decided whether to seek the death penalty if Chambers is convicted.
