Man Claims to Be Ex-Lover of Murder Suspect Chris Watts

There is a new twist in the case of Chris Watts, a 33-year-old man accused of murdering his pregnant wife and their two daughters at their family home in Frederick, Colo., earlier this month.

Watts had been suspected of having an affair with a coworker before the killing, according to a court document obtained by People. But now, an unidentified man has stepped forward, claiming he was in a relationship with Watts in an interview with HLN's Crime & Justice with Ashleigh Banfield.

The man, whose face was not shown in the interview, said the pair met online after Watts messaged him on the website MeetMe last June. He said they were in a relationship for about 10 months.

"I asked why his profile said straight. He said he was not out and not ready to be out as far as sexuality," the man said, adding, "I asked him to make sure he's not bisexual 'cause he had two children. He told me he didn't know. At that moment he was attracted to me as a male."

The man said he knew Watts was a father. But he did not know he was married until one of his daughters mentioned wanting to sleep in her parents' bed on one of their excursions.

"You never really know someone and you never really know what someone is capable of," the alleged lover said.

Police arrested Watts on August 15 and charged him with first-degree murder of his family members, among other crimes. Their bodies were discovered in oil tanks at Anadarko Petroleum, where Watts worked.

Watts confessed to strangling his wife Shan'ann, according to an affidavit obtained by People. Although Watts, in his telling, claims he "went into a rage" after she killed their daughters: 3-year-old Celeste and 4-year-old Bella.

The affair with the unidentified man has not been corroborated.

"[Chris] told me that if it were to ever come out that he would be shunned and he wouldn't be allowed to see his girls," the man said.

"Sociopaths can easily lead two different lives and feel two different emotions," the man said, "and [Chris] could have been telling me what I wanted to hear or what he thought I wanted to hear."

"I hope he gets convicted and I hope he stays in prison for the rest of his life," he said.
