Update: The execution commenced at 6:45 p.m. ET. Renteria spoke his final words and was pronounced dead at 7:11 p.m. ET.
Renteria started his last statement with a hymn in Spanish praising the Lord. He then led a prayer. Renteria then turned to the victim's family.
"Not a day goes by that I don't think about the events of that day... there are no words to describe what you are going through," Renteria told them.
Renteria then told his own family that he loved them.
"I'm a man of many faults and to those I've caused pain, I beg forgiveness... I'm sorry for the wrongs I've done."
As he was injected, Renteria started praying the Apostles Creed and said "I taste it, I taste it," before he stopped talking.
Update: The Supreme Court declined the application for relief. The execution will move forward. Court officials are preparing to move the ABC-7 crew to the prison for the execution now.
EL PASO, Texas (KVIA) -- The U.S. Supreme Court is reviewing David Renteria's request for a stay of execution.
Renteria's lawyers submitted the application to Justice Alito on November 16, just minutes before the scheduled lethal injection.
ABC-7's Stephanie Valle is in Huntsville, Texas to cover the execution. She was in the room as the stay application was announced and the execution was delayed.
ABC-7 confirmed with the Texas Department of Criminal Justice that this appeal pertains to the drugs used in the lethal injection.
"An injection of compounded pentobarbital… has unnecessarily and been left to degrade so that non-lethal degradants, some known to cause pain, can precipitate into the solution," the appeals states. "Mr. Renteria argued that the executioner’s unnecessary adulteration of the lethal injection drug violates his Eighth Amendment right to be free from cruel and unusual punishment and his right not to be deprived of life outside the due process of law.”
The TDCJ confirmed to ABC-7 that it cannot move forward with the scheduled 6 P.M. execution until there is a ruling issued by the high court.
David Renteria was convicted of the 2001 murder of Alexandra Flores, 5, and was sentenced to death in 2003.
Flores was seen on Walmart surveillance video leaving the store with a man who was later identified as Renteria.
Flores' partially burned body was found the following day, the morning of Nov. 19, 2001, in a parking structure near downtown El Paso.
