A gunman shot a convenience store clerk during a robbery attempt early Monday in Halethorpe, Baltimore County police said.

Officers responding to a report of a shooting at the Speedy Mart in the 3800 block of Hollins Ferry Road at 1:40 a.m. found the clerk with gunshot wounds to the upper and lower body, police said.
