Members of an anti-death penalty group are calling on Oklahoma Gov. Mary Fallin to halt the execution of a convicted killer.
The Oklahoma Coalition to Abolish the Death Penalty will hold a rally at the state Capitol on Monday seeking to spare the life of 56-year-old Garry Thomas Allen. Allen is scheduled to be executed Tuesday.
Allen was convicted and sentenced to die for the 1986 murder of his fiancee, Lawanna Gail Titsworth, in the parking lot of an Oklahoma City daycare.
Allen's attorneys say he was incompetent when he entered a guilty plea in the case and that his mental condition has continued to deteriorate, but appellate courts have rejected those claims.
A spokesman for Fallin says the governor expects the execution to proceed.
