South Carolina death row inmate Freddie Owens died by lethal injection on Friday during the state’s first execution in 13 years.

According to CNN, Owens, 46, was sentenced to death in 1999 for killing a convenience store clerk Irene Graves during a robbery in Greenville, South Carolina, when he was 19 years old.

Owens was pronounced dead at 6:55 p.m. ET, state officials said at a news conference Friday evening. He made no final statement.

South Carolina’s Supreme Court declined on Thursday to halt his execution and Gov. Henry McMaster chose not to grant Owens the requested clemency.

Owen’s attorneys filed for a stay of execution with the Supreme Court of the United States on Friday, hours before his execution, court documents show, but the court denied the request.

The inmate requested an emergency injunction in part because the violation of due process his attorneys said occurred when South Carolina’s Department of Corrections and Gov. McMaster did not provide Owens with basic information about the lethal injection drugs and the execution team’s qualifications, according to the emergency motion.

The state-mandated death marks the state’s first by lethal injection since it regained access to the medication required to perform the procedure following nearly a decade of lethal injection supply issues.
