A national Amber Alert was issued Wednesday for two Tampa-area boys after they were abducted by their "anti-government" parents, deputies say. A grandmother was tied up at a Tampa home Wednesday morning and the two children in her possession were taken by their parents in what investigators are calling a parental abduction/kidnapping. The parents are considered armed and dangerous. According to investigators, the couple lost custody of the two boys after an "anti-government" rally in Louisiana. The father was charged was possession of marijuana in the presence of the children.
