Police have charged two men in connection with an armed robbery of a Forestville liquor store Wednesday that ended with one of the suspects possibly shooting himself in the groin, authorities said.

Donnell J.Calloway, 25, and Gregory T. Evans, 27, are accused of demanding cash from the clerk at a liquor store about 5:40 p.m. Wednesday near the 3300 block of Walter Lane in Prince George’s County. After collecting some cash, the two men, both from the District, took off in a minivan that officers chased into D.C., police said.

The van then crashed near 57th and Clay streets in Northeast Washington, prompting a foot chase with police after the two men exited the van, authorities said.

During the chase, a Prince George’s officer fired his gun, but it is unclear whether that shot hit Calloway, police said. Police are continuing to investigate whether Calloway’s wounds were self-inflicted or from the officer’s gun.

“We won’t know for sure until forensic analysis is complete,” said Lt. William Alexander, a spokesman for the police department.

Calloway was sent to the hospital. He has not been released but is in stable condition, police said.

The name of the officer who fired his weapon has not been released, but he has been placed on paid administrative leave, a routine procedure. No officers were injured during the chase.
