A mother who threw her two children from an overpass in Dallas then jumped off the 20-foot-high bridge has been found not guilty of attempted murder and injury to a child.

A judge ruled Thursday that Khandi Busby is not guilty by reason of insanity and ordered her into a state mental institution.

Defense attorney David Pire says Busby believed God told her to throw her 6- and 8-year-old sons off the bridge on March 12, 2008 to protect them from Satan.

The boys' injuries have been treated and they are in foster care. Relatives say Busby is bipolar and had stopped taking her medication
