Florida death row inmate Loran Cole appeals to US Supreme Court to halt execution over lethal injection concerns due to Parkinson's disease.

Loran Cole, a Florida death row inmate convicted of a 1994 rape and murder, appealed to the U.S. Supreme Court for a stay of execution to challenge Florida's lethal injection procedures, claiming his Parkinson's disease could cause unnecessary pain. The Florida Supreme Court rejected Cole's appeal, and his execution is planned for Thursday, pending any last-minute federal court appeals.
