A judge in Louisiana has appointed two psychiatrists to evaluate whether a man accused of beheading his disabled son is sane enough to help with his defense.

Lafourche Parish Judge John LeBlanc also postponed the arraignment for Jeremiah Wright, 30, until Oct. 17, when he will hear testimony from Drs. Richard Richoux of New Orleans and Daphne Glindmeyer of Gretna,

Defense attorney Kerry Cuccia wouldn't say why he requested the evaluation by psychiatrists or why LeBlanc, who will be handling the case until it is allotted to a judge for trial, decided to appoint them. He says he filed three sealed exhibits.

He said they deal with Wright's current ability to help his defense, and not whether he was sane when 7-year-old Jori Lirette was killed Aug. 14. Wright is charged with first-degree murder.

Jori needed 24-hour care because of medical difficulties that included heart problems and cerebral palsy.
