In the months before his scheduled execution, Wendell Grissom's
legal team submitted a
clemency petition, claiming his original trial lacked evidence of neurological impairments. In January 2025, they filed an application with the
Oklahoma Pardon and Parole Board, supported by medical records and expert assessments showing brain atrophy in areas affecting decision-making and impulse control. A clemency hearing took place on February 5, 2025, where his attorneys argued that Grissom had not received a thorough
neuropsychological assessment during the trial and that these impairments might have impacted his behavior. The defense also provided statements from several 2008 sentencing jurors, who said knowledge of his cognitive issues could have led them to favor a
life sentence over
death penalty. Despite the presentation of new medical evidence and statements from former jurors, the Oklahoma Pardon and Parole Board voted 4–1 against recommending clemency.
Oklahoma Attorney General Gentner Drummond opposed the request, describing the case as a "
textbook example of why the death penalty exists" and asserting that Grissom's conduct during the 2005 incident was intentional and premeditated. Following the board's recommendation, Governor
Kevin Stitt declined to grant clemency. Grissom's case drew attention from national advocacy organizations such as Fair and Just Prosecution and the
Death Penalty Information Center, which issued statements opposing the denial of clemency. These groups raised concerns about the execution of individuals with documented neurological impairments and questioned whether the clemency process adequately reflected contemporary standards regarding the application of capital punishment. == Execution ==
