Convicted killer Chris Watts was put on a suicide watch just days after his tell-all interview on the horrific Watts family murder was made public, according to a report Wednesday. Watts killed his pregnant wife and two young daughters after an argument with his spouse on Aug. 13, 2018.

“Chris Watts is in clinical observation — suicide watch,” a Wisconsin Department of Corrections source told Radar Online. “Guards have to do 15-minute checks, which are recorded.”

The source said the 33-year-old told FBI agents in February that other inmates at the prison were screaming at him to kill himself.

"All the inmates would yell at him at night and would explain to him all the ways he could kill himself in his cell," one official who interviewed Watts reportedly said. This was the second time Watts was placed on suicide watch after prison officials feared he might take his own life.

Watts pleaded guilty in November to first-degree murder and other charges in the deaths of his wife and children. He was sentenced to five life sentences with no possibility of parole.

The news of the suicide watch comes just days after Watts' jailhouse confession surfaced where the killer opened up about the murder of his wife and his affair with his mistress in an interview with the Colorado Bureau of Investigation.

Giving details about the day he committed the murders, Watts told investigators: “I woke up that morning and I knew I had to do it. Why couldn’t I just let go? I don’t want to know what she saw when she looked back at me.”

Watts said he wanted to be together with his mistress Nikki Kessinger and wanted a divorce.

“With Shan'ann I never felt like I could be myself,” he said. “But with Nikki I could be myself. Nikki just wanted sex all the time, she wanted it when she wanted it. With Shanann it was just like okay.”

After killing his wife, Watts smothered his two daughters, Bella and Celesteir, and dumped the children’s bodies in an oil tank where they were found three days later.

During the interview, Watts also mentioned about the dangers he was facing while in jail, saying his fellow inmates wanted him dead as they urged him to kill himself by “drowning himself in the toilet or hanging himself,” according to state and federal agents.
