ATLANTA — The Georgia pardons board will review the case of a former high school football player who is set to be executed later this week for killing an ex-classmate in 1991.

The Georgia Board of Pardons and Paroles on Tuesday will hear the case of Daniel Greene, who is set to die on Thursday at 7 p.m. at the state prison in Jackson.

The former Taylor County standout was sentenced to death for killing 20-year-old Bernard Walker as he was trying to aid a store clerk who had been robbed and stabbed by Greene.

Greene confessed to the crimes to police, but later said he didn't remember committing the crime. He said an acquaintance had given him a cigarette earlier that day that may have been laced with a mind-altering drug.
