Mitchell's trial began on November 8, 2010. The defense acknowledged that Mitchell was in fact responsible for the crimes, but contended that he was legally insane at the time of the crime, and should therefore be found not guilty by reason of insanity. The insanity defense for Mitchell was rejected on December 11, 2010, when the jury found him guilty of kidnapping and transporting a minor across state lines with intent to engage in sexual activity. U.S. District Judge Dale Kimball sentenced Mitchell to life in prison without the possibility of parole. Mitchell is currently serving his sentence at U.S. Penitentiary, Terre Haute, a high-security federal prison in Terre Haute, Indiana.
