JACKSON, Georgia -- A man who fatally shot a pizza store manager during a 1994 robbery in which he stole a little more than $100 to give to his girlfriend has been executed by lethal injection.

Mark Howard McClain was put to death Tuesday at a state prison 50 miles (80 kilometers) south of Atlanta after his appeals were exhausted and a bid for clemency was rejected. He was pronounced dead at 7:24 p.m.

The 42-year-old was convicted of killing 28-year-old Kevin Brown during a robbery at a Domino's Pizza in Augusta, about 150 miles (240 kilometers) east of Atlanta.

Authorities said McClain gave the money to his girlfriend. She later testified against him.

McClain told jurors he intended only to rob the store, but shot Brown because he believed the manager was pursuing him.
