But, when he saw his girls again, they were almost unrecognizable.
"Their hair was dyed jet black, had been cut, and their eyebrows were jet black even," David said.
Even their glasses had been painted a different color.
"That was kind of upsetting, which I mean it was the least of our concern at the time but, still, why was their hair jet black?" he said.
He still hasn't heard word from their mother or the police about what they were doing.
"It's difficult because there's so many things I still want to ask, but there's so much I still don't know," he said.
David said he hasn't been grilling the girls about their trip and they haven't said very much about the extended visit.
Until he finds out what happened, he fears turning them over to their mother again. David said he's taken steps to delay court-ordered visitation.
