Investigators in Kansas have issued an endangered persons advisory for a mother and her two young daughters who they believe were “coerced to travel to Mexico to a religious rehabilitation facility.”
In a press release issued by the Kansas Bureau of Investigation (KBI), officials said the whereabouts of Martha Unger, 23, and her daughters, Madilynn Grace Unger, 2, and Haylie Faith Unger, 1, are unknown.
