A man who told North Charleston police he was robbed at gunpoint by a stranger was actually robbed while he was selling marijuana to a customer, according to a police incident report.

About 6:20 p.m. Thursday, police were called to the Whitfield on the Ashley subdivision for an armed robbery. A man told police that he and his friend had picked up an unknown man in front of an apartment complex on Dorchester Road and the man got into the back seat, pulled out a gun and demanded money. The man's friend said something different. He said they were robbed while they were trying to buy marijuana.

Police located a man matching a description both of the alleged victims gave of the robbery suspect, but after detectives took everyone to the police station, their stories changed. The men who had claimed to be victims were, in fact, selling marijuana and their customer robbed them, the report said.

The robber admitted to police that he just wanted to steal the marijuana, the report said.

Police confiscated 16.5 grams of marijuana and $200 in cash.

Kristopher P. Wham, 20, of St. Andrews Boulevard, Charleston, is charged with possession with intent to distribute marijuana. He was released on a $10,000 personal recognizance bond set Friday by Charleston County Magistrate Linda S. Lombard.

Shaquille Lamont Varns, 18, of Wayfield Circle, North Charleston, is charged with armed robbery, possession of a firearm during the commission of a violent crime and possession of a stolen firearm. He was being held in the Cannon Detention Center on $45,000 bail set by Lombard.

Police intended to file charges against the second victim of the robbery, who was released from custody before officers realized he was involved in the sale of drugs, the report said.
