A judge in Itawamba County turned down Loden's petition in 2008. The Supreme Court on Thursday said Loden didn't raise any new interest on which he might win a new trial.
Loden, a former Marine recruiter, was sentenced to death in 2001 in the slaying of 16-year-old Leesa Gray. He was also sentenced to 30 years on kidnapping and rape counts.
Gray disappeared June 22, 2000, while on her way home from work as a waitress at her family's restaurant in the Dorsey community. Her body was found dead the next day in Loden's van, according to court documents.
