The woman accused of being the evil ringleader who allegedly chained four mentally challenged adults locked in a Philadelphia dungeon will undergo a mental evaluation to decide whether she is competent to stand trial, RadarOnline.com has learned.

As RadarOnline.com previously reported, Linda Ann Weston was arrested last month and now faces a string of charges including criminal conspiracy, aggravated assault, kidnapping, criminal trespass, unlawful restraint and false imprisonment after three men and a woman were found chained in a Tacony, Pennsylvania house.

Municipal Judge Martha Neifeld agreed on Wednesday for a psychiatric assessment to be carried out in response to a request from the 51-year-old's attorney, George Yacoubian, based on the issues of mental retardation and low IQ, reported NBCPhiladelphia.com.
