Hammad Memon's attorney says the teenager's mental illness has worsened so much recently, he needs more time to prepare his defense.
Bruce Gardner filed a motion Thursday in Madison County Circuit Court asking for Memon's trial to be delayed 120 days. His trial for the murder of classmate Todd Brown is scheduled to begin on June 18.
Brown died after being shot in the hallway at Discovery Middle School in February of 2010. Prosecutors say Hammad Memon is responsible.
Memon had been free on bond, but has been in the Madison County Detention Center since being arrested in Dallas in April. Prosecutors believe he was trying to leave the country.
Gardner says since Memon came back from Dallas, Memon's mental state has declined. In the court documents, Gardner says Memon suffers from a severe mental illness. He says that mental illness has worsened since Memon's incarceration. Gardner says he needs more time to line up experts and prepare a defense for not guilty by reason of mental disease or defect.
