COSTCO SHOOTING: OFF-DUTY LA OFFICER IS NOT PAYING ANY FEES FROM THE An Intellectual Disability Death Penal A psychologist hired by Sparks & # 39; 's lawyers said in an affidavit last month that he "met the full criteria for diagnosing a" mental disability. " The Supreme Court banned execution of mentally disabled people in 2002, but states have their own discretion as to how mental retardation is to be determined.
His lawyers said that Sparks was not considered mentally handicapped at the time of the trial, but updates to the Handbook used by medical professionals to diagnose mental disorders would have changed that.

The US Supreme Court also rejected a request from Sparks lawyers to stop the execution, allegedly because the jury was inappropriately biased because an officer wore a tie with one Syringe, suggesting that he advocated the death penalty.  The Prosecutor General's Office said the jury's foreman said she had never seen the tie and did not believe it influenced the jury.
