Welner, who was paid $400,000 by federal prosecutors, concluded Brian David Mitchell suffers from multiple mental disorders but is competent for trial. His report suggests the former street preacher is exaggerating or feigning symptoms of illnesses to avoid prosecution.

Mitchell, 55, has twice been ruled incompetent since Smart was found in March 2003, walking a suburban street with him and his now-estranged wife. Those findings stalled a state court case, where Mitchell is charged with multiple felonies, including kidnapping and aggravated sexual assault.
