Charleston police have asked for help searching for a man accused of stealing beer from a gas station and threatening to shoot the store’s clerk.

Brian Clayton Shumpert Jr., 28, is wanted on charges of property crime enhancement, third offense driving under suspension, and intimidation of a witness, police said. Property crime enhancement is the statute used when suspects have been convicted of previous offenses against property, such as shoplifting, theft, vandalism or fraud.

The most recent charges against Shumpert are in connection with an incident that occurred shortly before 6 a.m. July 13.

A detective in an affidavit accused Shumpert of walking into the BP gas station at 1805 Savannah Highway and stealing an 18-pack of Miller Lite that was worth about $15. Shumpert then drove away from the scene, police said.

One of the store’s clerks recognized Shumpert and identified him to police, the affidavit states. The incident was also captured by a surveillance camera.

According to police, Shumpert returned to the gas station shortly before 2 a.m. July 27 and threatened to shoot the clerk. He also threatened to shoot the woman’s brother, police said.

Shumpert was convicted in October 2010 and March 2004 on charges of receiving stolen goods, police said.
