PARCHMAN, Miss. (AP) — A Mississippi man was put to death Wednesday evening for killing two men in a December 1995 robbery spree after the courts declined to stop the execution based on arguments that the inmate was mentally ill at the time.

Edwin Hart Turner, 38, died at 7:21 p.m. EST after receiving a chemical injection at the Mississippi State Penitentiary at Parchman, authorities said.

Turner was convicted of capital murder in the deaths of Eddie Brooks and Everett Curry, who were slain at two gas stations a few miles apart that were targeted by Turner and another armed friend in a spree that netted them about $400.

Brooks was shot to death first while working at one of the gas stations and Curry at the other while pumping gas when the pair went there next, toting rifles.

Turner’s accomplice testified against him and was sentenced to life in prison.

Wearing a red prison jumpsuit as he lay strapped on a gurney, Turner said, “No” when asked if he had a last statement. When the lethal chemicals began flowing, he closed his eyes, took a deep breath and appeared to fall asleep.

The sister and a cousin of victim Eddie Brooks watched the execution. The brother and son of his other victim, Everett Curry, also did.
