MONTGOMERY, Ala. (AP) — Alabama is preparing to execute an inmate for the shooting deaths of three fast food restaurant workers during a 1994 robbery.

Robert Bryant Melson, 46, is scheduled to die by lethal injection this evening at a south Alabama prison.

State prosecutors said Melson and another man who used to work at the restaurant, robbed a Popeye’s in Gadsden, 60 miles northeast of Birmingham. They said Melson opened fire on four employees in the restaurant’s freezer. Nathaniel Baker, Tamika Collins and Darrell Collier were killed. The surviving employee, Bryant Archer, crawled for help and was able to identify one of the robbers as the former worker.
