Collings is scheduled to be executed 6 p.m. Tuesday, December 3, for the 2007 murder of Rowan Ford, 9, a fourth grader at Triway Elementary in Stella.
The Court denied a writ of certiorari for Collings in April, meaning it would not even hear Collings' case.
Collings' attorney filed a motion to file a supplemental appendix to the petition for a writ of certiorari under seal. The court once again denied the request.
In the motion, the public defender also noted that another man, Rowan Ford's stepfather David Spears, had also confessed to the crime.
Afterwards, Collings threw the victim’s body in a sinkhole near Powell, Missouri in McDonald County. Collings also burned the rope he used to strangle the victim, the blood-stained clothing he wore during the attack, and his blood-stained mattress. Collings eventually confessed to the police.
Collings was convicted in Phelps County by a jury selected from Platte County. During the punishment phase of the trial, the jury found that Collings had tortured the victim in a way that was vile, horrible, and inhumane. The jury also found that Collings murdered the victim to prevent her from testifying against him regarding the rape.
Collings’s conviction and sentence have been reviewed by the Missouri Supreme Court, the United States District Court for the Eastern District of Missouri, the United States Court of Appeals for the Eighth Circuit, and the United States Supreme Court. No court has ever found any legal errors.
