OXFORD, Miss. (WCBI)-A Federal Judge has ordered a mental health exam for the man who admits he plotted an attack on Oxford High School. Earlier this week Chief U.S. Judge Michael Mills ordered 20 year-old Joshua Pillault to have a psychiatric evaluation in order to determine if he has a mental illness or defect that could be treated. Pillault was indicted last October after threatening to use fire and explosives at the school in an online game called “Rune-Scape.” Pillault said he planned to re-enact the 1999 Columbine Massacre on April 20th of this year. He faces up to 15 years in prison and a $500,000 fine.
