TULSA, Okla. (AP) - An Oklahoma man convicted of fatally shooting his fiancee in 1986 is scheduled to be executed Tuesday evening despite his pleas that he is mentally incompetent and ineligible for the death penalty.
Garry Thomas Allen is set to die by lethal injection at the Oklahoma State Penitentiary in McAlester.
He was convicted of shooting Lawanna Gail Titsworth outside a children's day care in Oklahoma City. Titsworth had moved out of the home she shared with Allen and their two sons four days before her death.
Members of the Oklahoma Coalition to Abolish the Death Penalty were present at a rally at the state Capitol on Monday seeking to spare the life of 56-year-old.
Allen's attorneys had argued that Allen 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.
Allen's attorney has requested a stay from the U.S. Supreme Court.Copyright 2012 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
