Colorado convicted triple murderer Chris Watts reportedly killed his eldest daughter, Bella after she saw him murdering her pregnant mother, Shanann Watts. According to an interview on The Dr. Phil Show which airs on March 5, Steven Lambert, who is the lawyer representing Shanann's family in the wrongful death lawsuit, claimed that the Rzucek family were only now informed of just how violently the father carried out the murders.

The whole incident allegedly started with 15-week pregnant Shanann threatening to keep Bella and Celeste away from her husband after she found out about his affair. This led to the man brutally killing all three of them and 4-year-old Bella reportedly spent her last moments alive begging Watts to not kill her, the exclusive interview on the show revealed.

Lambert told Dr. Phil in the clip: "The night in question Shanann came home. She and Chris had got into a fight. They made up. They were getting along really well. Later on, they got into a fight again. In that fight, he essentially confessed to having an affair, that he wanted a divorce. That it was pretty much over between them, and she had said something to the effect of, 'Well you're not going to see the kids again'." 

The lawyer then added: "As a consequence of that conversation he strangled her to death." The clip ended with Lambert revealing to Dr. Phil: "Bella walked in and asked what are you doing to mommy."

According to a previous report by MEA WorldWide (MEAWW), Watts had a discussion with FBI and CBI agents along with a member of the Frederick Police Department on February 18. The video of this conversation is due to be released for the public on March 7. The Rzucek's, Shanann's family, have already been briefed on what their former son-in-law said during this conversation.

Many people are speculating that this could mean that there might finally be some closure after the tragic deaths of pregnant Shanann, Bella, and Celeste Watts. The interview with Watts was held at the  Dodge Correctional Institution in Waupun, Wisconsin, where he was transferred to for his safety in December last year.

It is still unclear if the convicted killer is still there or if he used the interview with the investigators to move to another facility. The authorities have also said that they do not believe in the account that Watts gave them. He only ever confessed to killing Shanann and claimed he took the extreme step in a fit of rage after he saw her murdering their two children.

The local police and the FBI did not believe a word of that and subsequently charged Watts with three counts of first-degree murder after deliberation, two counts of first-degree murder of a child under the age of 12 and by a person in a position of trust, three counts of tampering with a deceased human body and one count of unlawful termination of a pregnancy. There now seems to be a possibility that the evidence in the heinous case could probably even exonerate Watts or implicate a second or a third person.

It was also speculated that the Weld County District Attorney may have uncovered some new video evidence based on the doorbell footage they released in late February which showed Shanann arriving home from a work trip shortly before she was murdered. Watts had initially claimed that he saw Bella dead and "blue" on her bed and Shanann "actively strangling" Celeste on the baby monitor.

If this alleged footage was obtained from the system, it could be used to either confirm or deny his allegation that his wife killed their children and then he killed his wife. Watts had said that he saw his pregnant wife "on top of Celeste" and that's when he ran into the room to stop it but he was allegedly too late. He then told the authorities that he strangled Shanann.

The same officials who worked on the case for the FBD, FBI, and CBI were the ones who visited the convicted father in jail. The man only admitted to murdering his wife and then burying her in a shallow grave. He also said that he dumped the bodies of Bella and Celeste into large oil tanks after he failed a polygraph test.
