A 21-year-old Omaha man faces a new charge of motor vehicle homicide following a crash in which another man died.

Sergio Valdivia-Marquez previously faced charges of driving under the influence causing serious injury and reckless driving in the crash just after midnight Saturday.

Omaha television station KETV reports (http://bit.ly/PDXugQ) that the Douglas County Attorney’s Office filed the new charge following the death Wednesday of 18-year-old Michael Tran.

Tran was taken off life support and died around 10 a.m. Wednesday. An autopsy has been scheduled for Thursday.

Police say Valdivia-Marquez’s headlights and tail lights were not functioning properly and that he was speeding when he ran a red light and slammed into Tran’s car.
