Get Amie and kids back to USA from Panama

We are raising money for my sister Amie Navarre who cant bring her American citizen family back to America unless she has excellent legal representation. She cant speak Spanish in Panama, and has to rely on her 15 year old daughter Charli to be her interpreter. Amie can leave, Charli can leave. But her son Asher and daughter Justice are on no fly restriction. She cant leave her children there. Her separated husband is forcing them to stay out of some control trip. He has warrants for domestic violence in Colorado...USA. so he is trapping them in Panama
