A man convicted of fatally shooting a delivery driver in 1998 was executed Thursday evening in Alabama.

Keith Edmund Gavin was pronounced dead at 6:32 p.m. CDT following a chemical injection at the William C. Holman Correctional Facility in southwest Alabama, authorities said. The 64-year-old inmate was convicted of capital murder in the shooting death of William Clayton Jr. in Cherokee County. Clayton, a 68-year-old courier service driver, had driven to an ATM in downtown Centre on the evening of March 6, 1998. Clayton had just finished work and was getting money to take his wife to dinner, according to a court summary of trial testimony.
