JAY – A Grove man accused of killing his father has been sent to the Oklahoma Forensic Center in Vinita, after entering into a plea agreement with the state claiming he was not guilty by reason of insanity.
Mark Henry Thurman, 26, was sent to the mental health facility on January 6 after the state and his attorney agreed upon a plea of not guilty by reason of insanity on December 23 in district court.
A hearing date of Jan. 30 at 10 a.m. has been set in Delaware County.
Thurman is accused of murdering his 61-year old father, Bob Thurman, on November 29, 2005, at the Thurman’s home in the Orchard Grove Housing area, by shooting him in the back of the head.
According to incident reports filed in district court, Thurman was released Nov. 28, 2005 from the Missouri State Penitentiary, spent the night in his parents’ home, and fatally wounded his father the next day.
Thurman fled the scene and was later apprehended in Raton, NM on November 30.
He was formally charged with first-degree murder on December 1, 2005.
Thurman pled not guilty by reason of insanity during the felony docket on August 7, 2006, and his defense attorney, Kenny Wright, asked for a continuance in order for Thurman to receive psychological testing.
He was ordered to Eastern State Hospital in Vinita on January 8, 2007 where he stayed until May 16, 2007 when he appeared in district court and was found competent to stand trial.
Thurman asked to enter into a plea agreement with the state on August 7, 2007. At that time he asked for the death penalty.
According to documents filed in the district court clerk’s office, District Attorney Eddie Wyant asked that the empanelled jury impose the penalty of death by lethal injection against Thurman.
The bill of particulars filed in the case stated that not only had Thurman killed his father, but that the lives of his son (Thurman’s) and the child’s mother were also in danger at the time of the shooting.
The document stated that not only was Thurman intending to kill his entire family, but he was going to “just keep killing as he wanted to be the next ‘Chainsaw Massacre’ or the next ‘Natural Born Killer’.”
Judge Robert G. Haney ordered that Thurman undergo an independent mental evaluation although he had earlier been evaluated by the states physicians and been found competent to stand trial.
On September 12, 2007, Thurman retained defense attorney John Echols of Sapulpa, OK, who announced that he was not and could not be prepared for trial on the following spring felony disposition docket.
Thurman appeared in court for a post competency review hearing and was found competent to stand trial for the second time on February 6, 2008.
