JACKSON, Miss. (AP) — The U.S. Supreme Court refused Tuesday to allow a Gulfport, Miss., man to file another challenge to his death sentence.
William Gerald Mitchell was sentenced to death in 1998 in Harrison County for the killing of Patty Milliken, a 38-year-old store clerk, on the night of Nov. 21, 1995.
Authorities said Mitchell took Milliken from the store where she worked, brought her under the north end of the Popp’s Ferry Road bridge and killed her by beating her and driving his car over the top half of her body.
Mitchell had requested permission to file an appeal on claims that his attorney should have done a better job and that he is mentally retarded and ineligible for execution.
An earlier post-conviction claim was denied by the Supreme Court in 2005.
