ST. LOUIS (AP) - A St. Louis area man convicted of kidnapping, raping and strangling a 17-year-old girl in 1989 could become the fifth person executed in Missouri in five months.

Jeffrey Ferguson is scheduled to die at 12:01 a.m. Wednesday at the state prison in Bonne Terre.

Kelli Hall was abducted from a St. Charles gas station. Her frozen body was found 13 days later, on Feb. 22, 1989, on a St. Louis County farm.

Gov. Jay Nixon is weighing a clemency request, and court appeals are pending.

Missouri switched to a one-drug execution method last year. Ferguson's execution would be Missouri's fifth straight execution using a single drug, pentobarbital. The state obtains the drug from a compounding pharmacy it has refused to name.
