Help Reunite These Girls with Their Mom

I’m setting up this gofund me for my sister. 3 weeks ago her whole life was flipped upside down. Her husband was doing awful things behind her back which caused her children to be taken out of her home till they could clear her. She’s filing for divorce and has done everything DHS and the officers have asked her to do. Therefore she got the youngest child back but the other two girls were in her ex husband or their fathers by care and he has now gone behind her back to file for emergency custody of them. She can’t even see them right now unless it’s supervised.
