The psychiatrist, Michael Welner of New York City, may testify at a competency hearing next month, the Salt Lake Tribune reported. Prosecutors referred to his 206-page report in a motion to allow his testimony, which the defense wants to bar.
In his report, Welner said Mitchell has antisocial and narcissistic personality disorders and is a pedophile. But he said Mitchell's bizarre courtroom behavior is not genuine.
For example, Mitchell apparently began singing during courtroom appearances only after negotiations for a plea bargain failed in 2004.
Mitchell allegedly abducted Smart, then 14, from her bedroom in 2002 and raped her repeatedly at a campsite where he lived with his wife, Wanda Barzee. He and Barzee were arrested in 2003 in Sandy as they walked with the girl.
