JACKSONVILLE, Fla. -

A 23-year-old Jacksonville man was sentenced this week to mandatory life in prison for his involvement in a 2011 armed robbery.

Charles Culp was convicted last month on two counts of armed robbery and one count of possession of a firearm by a convicted felon.

In February 2011, Culp and his co-defendant, Cleona Housandtroutman, held up the Subway restaurant on Parental Home Road, prosecutors said. They said the two were armed with handguns and wore bandanas on their faces during the robbery.

Culp forced customers to the floor and took money from the business as well as customers. Culp and Housandtroutman were captured by the Jacksonville Sheriff's Office minutes after the crime occurred.

Housandtroutman is charged with one count of armed robbery in the crime. Her trial date is pending.

Culp, convicted in 2007 on a charge of armed robbery, committed this crime within three years of being released from prison. Culp is also charged in two unrelated armed robbery cases.
