ATLANTA (AP) — A Georgia death row inmate convicted in the death of his 15-year-old neighbor is set to be executed.

Marcus Wellons, who's 59, is set to be put to death Tuesday evening at the state prison in Jackson. He was convicted in 1993 of raping and murdering his 15-year-old neighbor, India Roberts, a high school sophomore in the Atlanta suburbs.

The Georgia Board of Pardons and Paroles on Monday denied clemency for Wellons. His lawyers last week filed two legal challenges with the aim of halting his execution. A federal judge on Monday rejected one challenge, while the other is still pending.

Roberts' naked body was found in a wooded area near the apartment building with cuts on one side of her face and ear, and bruises on her neck.
