Chris Watts' Alleged Ex-Lover Speaks — but He's Not the Co-Worker Police Say Chris Was Seeing

An unnamed man on Tuesday night came forward claiming to have been a former lover of triple-murder suspect Chris Watts, who is accused of killing his pregnant wife, 34-year-old Shan’ann Watts, and their two young daughters in their Frederick, Colorado, home earlier this month.

The man — whose name and face were not shown — described the purported relationship in an interview on HLN’s Crime & Justice with Ashleigh Banfield.

The man said he was not the co-worker with whom Chris, 33, was allegedly cheating on his wife at the time of the three slayings.

A motive in the murder case has not been confirmed as allegations of Chris’ infidelity draw greater scrutiny. Those who know the Watts have described a seemingly happy union possibly beset by mounting tension.

“It’s beyond belief, really,” friend Kris Landon told PEOPLE. “And it makes you wonder about other people you know. If this couple who seemed so perfect was like this, what are the other couples like?”

The man told HLN that he and Chris were allegedly in an approximately 10-month relationship after meeting online last June. They saw each other off and on through the spring, ending things in March or April, the man said.

The unidentified man’s story has not yet been independently corroborated by news outlets, including PEOPLE, but his account of an alleged relationship with Chris does contain details about Chris’ life that are not readily available online and in public documents. Identifying information about Chris’ truck and his home matches PEOPLE’s reporting.

A source close the investigation tells PEOPLE that Chris has had relationships with both men and women outside of his marriage.

Couple in Shock as They're Charged With Murder in Death of Malnourished Daughter in Michigan

A Michigan couple has been charged with murder as they stand accused of starving their 10-month-old daughter. 

A judge told Seth Welch and his wife, Tatiana, both 27, they faced a life sentence with no possibility of parole if they are convicted.

They are accused of starving their infant daughter, Mary, who was found dead inside the Welch's farm near Grand Rapids on August 2.

His jaw dropped when the judge read off the charges, which include felony murder and child abuse, and she sobbed uncontrollably during Tuesday’s hearing. 

The baby was so malnourished she had sunken eyes and cheeks and no pulse when paramedics found her at their home, according to officials. 

Hours later, Seth Welch posted a message on Facebook saying: “Heart is absolutely shattered.  Woke up to Mary dead in her bed this morning ... Just numb right now."

An autopsy found the cause of death was malnutrition and dehydration due to neglect by adult caregivers.

The parents reportedly told police they noticed the baby was “skinny and underweight" a month ago but did not seek medical attention because of their religious beliefs and a mistrust in medicine and the government. 

Seth Welch’s Facebook page is are filled with rants against government, Disney characters, and even the "Harry Potter" series.
