Now, Sergio Valdivia-Marquez faces a charge of motor vehicle homicide, along with DUI and reckless driving.
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.
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.
