Officers responded to the 7-Eleven located on the 400 block of North Zang Blvd. at about 11 p.m., Dallas Police said.
Two men had reportedly gone into the store and allegedly stole two 12-packs of beer each, the Dallas Morning News reports. Johnson, the clerk working at the store, followed them outside to their vehicle, then allegedly fired five shots at them as they got away.
One of the shoplifting suspects was found badly wounded in a pickup truck about a mile away, KDFW-TV reports.
