Cops revealed Chris Watts made the shocking confession late yesterday, according to .
The dad is said to have been detained just hours after he said in a TV interview: "I have no idea, like, where they went."
He added: "I don't feel like this is even real right now. It's like a nightmare I can't wake up from."

He has not yet been charged and it is not known if he has a lawyer.
The FBI and Colorado Bureau of Investigation are also investigating the incident, local legal sources told Denver7.

Watts also said his wife told him she was planning to take their girls to a friend’s house and that was the last he had heard from her.

Watts claimed he texted his wife numerous times but didn't get any response which he thought was odd.
He then raced home but found it empty and quickly filed a missing persons report with the cops.

"I don't feel like this is even real right now.
"It's like a nightmare I can't wake up from."
The Frederick Police Department confirmed they had made an arrest "in connection to the missing person's case" of Shannan and her daughters.
