that his ex is keeping the whereabouts of his son Collin from him.
"I have an idea where he is but I don't really know where he is," he said, adding, "I mean, I ask but she doesn't tell me.
He didn't elaborate on what that meant, but alleged that his other children also do not know where Collin is.
In May, the two were still going strong, and were spotted on a PDA-filled date in Philadelphia.

But Jon slammed Kate’s claims about their son, who reportedly was expelled from school along with his sister Alexis for violent and abuse behavior against other students in 2010.

He also said that he is seeking joint custody of his kids, and if it's granted to him, that would require TLC to stop filming the reality series.
Kate has yet to comment on her ex-husband's allegations.
Jon said Kate, “says that Collin is in a special school for special needs kids with behavioral problems,” but claims he was given a different story by law enforcement officials. The absentee father also claimed that his other children have “no idea,” where Collin is.
Jon said that he begs his wife to inform him about their son’s whereabouts, but that she has so far refused to reveal any details. “They know that their mom told them that he has behavioral issues,” he said.
