JACKSON, MS (Mississippi News Now) -
Death row inmate Gary Carl Simmons Jr., was pronounced dead at 6:16 p.m. Wednesday.
He was the sixth inmate executed in Mississippi this year.
Simmons, 49, a former grocery store butcher, was convicted for the 1996 killing and dismemberment of Jeffery Wolfe.
Wolfe was shot and his body dumped into a south Mississippi bayou. Simmons was also convicted of kidnapping and raping Wolfe's girlfriend.
Simmons' former brother-in-law, Timothy Milano, also was convicted of killing Wolfe, who drove to Mississippi from Houston with the woman to collect a drug debt. Milano received a life sentence.
Authorities said Milano shot Wolfe, but Simmons planned the killing.
