A man convicted of killing his ex-girlfriend by setting her on fire using gasoline was executed in Texas on Feb. 22 according to the Associated Press.

Carl Blue, 48, was sentenced after the U.S. Supreme Court refused his final appeal for attacking and killing his former girlfriend Carmen Richards-Sanders in Sept. 1994. He also reportedly tossed gasoline on a man in her apartment, but the man survived and testified against Blue.

Blue claimed it was supposed to be a prank, but prosecutors were able to prove it was an intentional attack started in a jealous rage.

Blue spoke to Sander's daughter, Terrella Richards, before being executed in the death chamber viewing area.

"I never meant to hurt your mama," Blue said while strapped to a gurney. "If I could change that, I would. I hope you can forgive me."

Blue then turned to his parents, who were watching in another room, that he loved them and admitted he did something terribly wrong.

As the lethal drug was put into Blue's body, he took around 12 breaths before saying "I feel it," and then slipped into an unconsciousness before being pronounced dead at 6:56 p.m.

"Cowboy up. I'm fixin' to ride, and Jesus is my vehicle," Blue was quoted saying shortly before dying according to the Associated Press.

Richards wouldn't speak with the media after the execution was over, simply stating she wanted to move on with her life now that this "journey" was over.

Prosecutors were able to prove that Blue walked seven miles from his home to a convince store, smoked crack and drank an undisclosed amount of malt liquor, before buying 50 cents worth of gas and put it inside of a "Big Gulp" cup according to the Associated Press.

Blue then waited outside of Richards-Sanders apartment, and as she opened her door, he "doused her" and lit her on fire. With the remaining gas, he walked up to her apartment, and after discovering a man inside, he threw the rest inside and set him on fire.

"He had only one true love in his life ... and here she was with another guy," said John Quinn, the lead defense attorney at Blue's 1995 trial.

Shane Phelps, a prosecutor at Blue's trial, confirmed that the two had been broken up for months before the attack and Richards-Sanders was trying to "move on with her life."

Blue turned himself into the police the same day.

"When I went to knock, she snatched the door open and had a cigarette," Blue told police in a tape-recorded statement played at his trial according to the Associated Press. "I wasted gas on both of them. And she caught on fire, and he caught on fire, and I took off running. I was scared, man."
