OMAHA, Neb. (AP) — An Omaha man accused of causing a crash last week that killed a 16-year-old girl has been charged with motor vehicle homicide and driving under the influence.

Douglas County Attorney Don Kleine said Wednesday that bond has been set at $750,000 for 28-year-old Tyvinn Smith. Smith’s preliminary hearing will be July 18. He faces more than 50 years in prison if he’s convicted.

Tyvinn remained jailed Wednesday and could not be reached for comment.

Kleine says Smith was speeding when he slammed into the back of a car on Sorensen Parkway around 10:45 p.m. Friday, killing Janis Brown and injuring two others.

Kleine says that at the time of the crash, Smith had a blood-alcohol level of .102 and had cocaine and PCP in his system.
