Authorities are searching for a man believed to be the last person seen with a University of Virginia student before she disappeared on arrest warrants charging him with reckless driving.

But they also want to talk to him about the missing teen.

Charlottesville Police Chief Timothy Longo said Sunday that Virginia State Police issued warrants for Jesse Matthew on a charge of misdemeanor reckless driving. Matthew hasn't been charged in the disappearance of 18-year-old Hannah Graham, who was last seen early on Sept. 13.

Longo said police want to talk to Matthew, who was seen with Graham before she disappeared.

Longo says Matthew had stopped by a police station Saturday with several family members and asked for a lawyer. He was given a lawyer but left, driving at a high rate of speed.
