A man convicted of killing five people including his ex-wife in a 1997 shooting rampage near Houston has been put to death.
Coy Wesbrook, 58, on Wednesday became the eighth inmate executed this year in the U.S. and the fourth in Texas, the most active capital punishment state.
The execution was delayed about 90 minutes after a death penalty opponent's late appeal that was rejected hours earlier appeared to be headed to a higher court.
Wesbrook testified at his trial that he and his ex-wife had talked about reconciling and then he showed up at her Channelview apartment and found people partying.
He said she humiliated him by having sex with two men while he was there and that some at the party taunted him as he tried to leave.
He grabbed a rifle from his truck and shot all five people there.
Killed were Wesbrook's ex-wife, Gloria Jean Coons, 32; Coons' roommate, Diana Ruth Money, 43; and three men: Antonio Cruz, 35; Anthony Ray Rogers, 41; and Kelly Hazlip, 28.
The appeal by the death penalty opponent, Houston activist Ward Larkin, asked for Wesbrook's trial court to again review claims that the former security guard and delivery driver was mentally impaired and ineligible for the death penalty.
The Texas Court of Criminal Appeals, the state's highest criminal court, ruled the appeal was improper.
