The man accused of killing and dismembering his disabled son was found not guilty by reason of insanity Friday morning.Watch videoJudge John Leblanc issued the ruling in the case against Jeremiah Wright.Leblanc said because this was a capital case, he is committing Wright to the East Louisiana Mental Health System in Jackson, La."The District Attorney's Office reluctantly agrees to let the judge make the ruling. But given the evidence presented, it's overwhelming." said District Attorney Cam Morvant. "This closes the book on the situation."Watch: DA on Jeremiah Wright Wright, 32, was arrested in Thibodaux and accused of gruesomely killing his son Jori Lirette, who was fed through a tube, confined to a wheelchair and required around-the-clock care.The boy, who had cerebral palsy, was killed on Aug. 14, 2011, and his severed head was found in the yard of the house Wright shared with Jori's mother, Jesslyn Lirette.Additional remains were found in trash bags nearby.A forensic psychologist said Wright told him that he killed Jori because he thought his son was a robot. Wright told the psychologist that he "wanted to see its insides - to see what it's made of."After police said Wright dismembered his son, Wright told the psychologist that he "found foam at the joints and a plastic skull."Last fall, WDSU reported that Wright had been checked out of a mental health facility after state doctors declared him competent to stand trial. Defense attorneys questioned the finding at the time.Friday, Dr. Farrah Deland, who evaluated Wright on four occasions, including last month, testified that Wright was suffering from a severe mental disorder with psychotic symptoms, hallucinations and was completely off his medication at the time of the killing.Deland also testified Friday that Wright was a chronic marijuana user, which could have led to his behavior.Wright also had a thought disorder and a fixed false belief, Deland said."He heard voices at the time," she said. "He thought that people on TV were talking directly to him."Deland explained that Wright believed that star actor Matthew McConaughey would talk to him, telling Wright that he was a good person and used expletives when speaking to Wright. He also thought morning show hosts Regis Philbin and Kelly Ripa spoke to him, and Wright believed everyone was involved in a "grand experiment."One year ago attorneys for Wright successfully argued that their client did "not have the present mental capacity to proceed" with a trial. Leblanc agreed in a February ruling that committed Wright to a state facility for treatment.The order followed six days of testimony, during which at least a dozen experts and investigators took the stand. Testimony from some indicated that Wright believed his son was a robot or CPR dummy put into his home as a government experiment to teach him about life.The killing qualified as a capital case because the victim was under the age of 12. Wright is represented by New Orleans-based attorney Kerry Cuccia, who leads the Capital Defense Project of Southeast Louisiana.Wright spent most of 2013 in the care of the Eastern Louisiana Mental Health System.Prior to the killing of Jori, Wright had only a spotty record with minor criminal incidents - none of them violent in nature.The crime rocked the city of Thibodaux, which had not seen a murder in three years prior. Veteran investigators reportedly broke down while working the case.Police Chief Scott Silverii told WDSU at that time that Wright observed officers who arrived at his home and was "stoic, emotionless, non-confrontational."Jori's mother described her son as the light in her life."He was my star. No matter what people think or say. He was always top priority in my life," said Jesslyn Lirette. "Now you're in heaven as an angel. You're a beautiful star and you will always shine bright inside my heart -- inside of everybody's heart."On Friday, Jori's family issued the following statement:"On behalf of Jori Lirette and family, we ask that we (want to) finally be able to mourn the loss of Jori at peace. We ask the negativeness be unspoken. We just (want to) have peace. We are supportive of the D.A. discussion, and we are comfortable with the outcome. We are still in shock over the loss of Jori. All we are asking for is to be left alone so we can carry on with our live and honor Jori's memory everyday. He is deeply missed by his friends, family and his mother. No words can express the pain we all feel or the loss of Jori and the impact it had on us all. Jori was a loveable child and he will be deeply missed. We (want to) heal and have our memories of Jori that are precious to us."Related:Pre-trial hearing set in Thibodaux decapitation caseJudge: Man accused of killing, dismembering son fit for trialCompetency hearing may be imminent for father accused of beheading sonCourt considers sanity of man accused of dismembering sonI-Team: Man accused of killing special needs son now set for trialCommunity reacts to ruling on Thibodaux's boy's deathFather tells doctors beheaded son wasn't realSign up for our email newsletters to get breaking news right in your inbox. Click here to sign up!13484466
