A New York psychiatrist is expected in federal court to discuss the religious writings of the man accused of abducting Elizabeth Smart.

According to Dr. Michael Welner, some of Brian David Mitchell's writings claim that Smart went with him willingly and with the permission of her parents.

Mitchell drafted the "Book of Immanuel David Isaiah II" after his arrest and interrogations by police in March 2003.

Welner is testifying as part of a 10-day competency hearing to determine whether Mitchell can stand trial in U.S. District Court. The competency hearing enters its second week Monday.

Mitchell is charged with kidnapping and unlawful transportation of a minor across state lines.

Prosecutors contend Mitchell is competent and faking an illness to avoid prosecution.
