A man who killed and sexually assaulted an aspiring artist in central Florida is scheduled to die by lethal injection.

Darius Kimbrough is set for execution at 6 p.m. Tuesday at Florida State Prison.

Kimbrough was convicted in the 1991 slaying of Denise Collins. The 28-year-old woman was attacked in her Orlando apartment while she was sleeping.

In October, the state Supreme Court denied Kimbrough's appeal, rejecting the argument from Kimbrough's lawyers that he shouldn't be executed because the jury recommendation wasn't unanimous.

His attorneys have appealed to the U.S. Supreme Court.
