Texas has executed a man convicted of murdering a woman by stabbing her repeatedly after breaking into her San Antonio home in 2004.
TaiChin Preyor, 46, died by lethal injection at the state's death chamber in Huntsville, a prisons official said.
The execution was delayed for more than three hours to allow the US Supreme Court time to hear an appeal from Preyor's lawyer to spare his life, which the court rejected.
The execution was the 543rd in Texas since the US Supreme Court reinstated the death penalty in 1976, the most of any state.
"First and foremost I'd like to say, Justice has never advanced by taking a life by Coretta Scott King. Lastly, to my wife and to my kids, I love y'all forever and always. That's it," Preyor was quoted as saying in his final statement by the Texas Department of Criminal Justice.
Preyor was convicted in the 2004 killing of 24-year-old Jami Tackett
He also stabbed a man who was with her, but who survived.
Lawyers for Preyor launched the appeal at the court yesterday, arguing that prior counsel was incompetent and included one lawyer who lost his licence two decades earlier and another attorney with no death penalty experience who used Wikipedia to navigate the Texas death penalty system.
Lawyers for Texas asked the Supreme Court to deny the appeal, saying Preyor had been justly sentenced and should have raised concerns about prior counsel earlier.
