A man accused of beheading and dismembering his son was sent to a state mental hospital Friday, the Lafourche Parish Sheriff’s Office says.

Jeremiah Lee Wright, 30, was sent to the Eastern Louisiana State Mental Health System in Jackson from the Lafourche Parish Detention Center in Thibodaux, the Sheriff’s Office said Saturday in a news release.

Authorities arrested Wright on Aug. 14 on a count of first-degree murder in the death of his 7-year-old disabled son, Jori Lirette.

The boy’s head was found in the yard. His torso, lower legs and forearm were found in a plastic bag in the trash can.

Jori, who was born three months premature, could say only a few words and needed a wheelchair and feeding tube. He was killed while his mother was out.

At a hearing Oct. 18, 17th Judicial District Judge John LeBlanc ruled that Wright cannot understand the charge against him or help in his defense.

The judge based his decision on reports from two court-appointed psychiatrists who examined Wright.

LeBlanc ordered monthly reports on Wright’s progress in Jackson and scheduled a Jan. 31 status conference on the case.
