Mississippi’s Supreme Court postponed Tuesday’s scheduled execution of Willie Jerome Manning, days after federal authorities acknowledged errors in FBI forensic testimony at his 1994 trial and just five hours before he was to die by lethal injection.

The court gave no reasoning for its decision, nor did it say what further action might be taken or when.

Manning was convicted of killing Mississippi State University students Jon Steckler and Tiffany Miller, whose bodies were discovered at a secluded spot outside Starkville, Miss., on Dec. 11, 1992.

The ruling to stay the execution came after an offer by the FBI to retest evidence in the case last week because some testimony by FBI expert Chester E. Blythe was scientifically invalid.
