The U.S. Supreme Court Tuesday refused to hear appeals from four Mississippi death row inmates.
The justices without comment declined appeals sought by condemned prisoners Frederick Bell, Blayde Grayson, Stephen Elliot Powers and Leroy Lynch.
Bell was convicted in 1993 for killing a Grenada County grocery store clerk.
Grayson was convicted in the 1996 slaying of 78-year-old Minnie Smith during a house burglary in George County.
Powers was sentenced to death for the 1998 killing of a University of Southern Mississippi student.
Lynch was sentenced to death in 1998 for his role in the shooting death of 74-year-old Richard Lee outside Lee's home in Boyle.
