CASPER, Wyo. (AP) — A Riverton man accused of kidnapping a 95-year-old Casper woman has pleaded not guilty.

The Casper Star-Tribune reports 20-year-old Kyle Martin pleaded not guilty to six felony charges on Thursday.

He could face up to life in prison if convicted.

Martin's trial date is to be determined.

Police say they found Martin on March 20 driving a stolen car with the woman in the trunk of the car.

Police say the woman had cuts on her head and face.

According to court documents, the woman told police that two armed men kidnapped her.

A Casper Police Department spokesman said Wednesday that they do not have the second suspect in custody.
