“He's been refusing to come back and we were worried about him, we were in contact with the American Embassy telling them we were worried about him. The American authorities said, 'He's over 18 we can't do anything,’” said Michael Davey, who split from Sandford’s mother when the boy was four.
Well, yes, you can do something. You can report an illegal alien in the US in violation of US immigration law, overstaying a visa, and tell ICE to hunt him down and deport him.

Sandford had fallen in love with an American girl when he was 18 but she moved back home to New Jersey with her parents, according to Davey.

He became so depressed that his parents gave him the money to travel to the U.S. to live closer to his girlfriend. Davey said he didn’t know if the couple were still together as his son rarely shared details of his private life.
Well, we need to know who she is, what her story is, and what if anything she might have had to do with this. A madwoman Hillary Supporter? A crazy Soros-funded Bernie Supporter? You never know. I hope the FBI is on this. Sounds like the parents think someone put him up to it.
