Texas executes man convicted of killing prison guard with shank

AUSTIN, Texas (Reuters) - Texas executed a man on Thursday convicted of murdering a prison guard in 1999, after the U.S. Supreme Court rejected a last-minute appeal to spare his life despite arguments by his lawyers that he was innocent.

Robert Pruett, 38, was put to death by lethal injection at the state's death chamber in Huntsville and pronounced dead at 6:46 p.m. (2346 GMT), the Texas Department of Criminal Justice said. He was the 544th person executed in Texas since the U.S. Supreme Court reinstated the death penalty in 1976, the most of any state. It was Texas' sixth execution this year.

"I’ve hurt a lot of people and a lot of people have hurt me. I love ya’ll so much. Life don’t end here it goes on forever. I’ve had to learn lessons in life the hard way. One day there won’t be a need to hurt people," Pruett was quoted as saying in his last statement by the criminal justice department.

About an hour before the scheduled execution, the Supreme Court said it rejected Pruett's petition. It did not provide a reason.

Pruett, sent to prison as a teenager and serving a 99-year sentence as an accessory to a murder committed by his father, was convicted of killing prison guard Daniel Nagle by stabbing him repeatedly with a shank.

The Nagle family said in a statement released by the department: "Though it has been over 18 years since he was taken from us, we still miss Daniel every day and the execution will in no way minimize our loss."

Prosecutors said he murdered the corrections officer because Nagle had reprimanded him for carrying a sandwich into the recreation yard. Torn pieces of the disciplinary report on Pruett were found near Nagle's body.

"No witnesses testified they observed the attack, and no physical evidence connected Robert Pruett to the murder," Pruett's lawyers wrote in their petition to the Supreme Court filed on Tuesday.

They said Pruett, who has maintained his innocence, was convicted on the unreliable testimony of prison informants and that neither Pruett's fingerprints nor DNA material were found on the torn report. Lawyers had also asked the state to release the shank and Nagle's clothes for DNA testing after inconclusive tests took place in 2000.

In a legal filing with the Supreme Court, the state of Texas said: "Pruett has raised nothing new that casts any doubt on his guilt."
