Convicted triple murderer Chris Watts, who is currently serving multiple life sentences in a Wisconsin jail for murdering his pregnant wife and two young daughters, reportedly drove the kids with their dead mother's body to an oil field 45-minutes away from their home. Shanann Watts' family lawyer Steven Lambert revealed in an exclusive interview on The Dr. Phil Show that the father smothered his youngest child to death with her favorite blanket and then killed 4-year-old Bella after she witnessed her sister die. 

Lambert said on the show that Bella also pleaded with her killer father for her life. The attorney, who is representing Shanann's family, the Rzucek's, in a wrongful death lawsuit, revealed the disturbing details in part 1 of the interview which aired on March 5. He also said that Bella had walked in on her father disposing of her pregnant mother's body when the murders took place in August last year, CBS12 reported.

Watts, who is from North Carolina, recently revealed to investigators from the FBI, CBI, and a member of the Frederick Police Department, more gruesome details about how he killed Shanann, Bella, and Celeste in an interview that is reportedly an hour long. It is based on this new prison interview that Lambert said in the Dr. Phil exclusive that Bella had walked in on her father disposing of Shanann's body by wrapping it in a sheet.

Lambert said: "Bella walked in and asked, 'What are you doing with Mommy?'." Watts then reportedly told Bella: "Mommy is sick and we need to take her to the hospital to make her better." According to a previous report by MEA WorldWide (MEAWW), Shanann and her husband had gotten into a fight in their Colorado home shortly before she was murdered.

He told Dr. Phil: "In that fight, [Chris] essentially confessed to having an affair, that he wanted a divorce, that it was pretty much over between them. [Shanann] said something to the effect of, ‘Well, you’re not going to see the kids again.’ As a consequence of that conversation, he strangled her to death."

After he was arrested, Watts told the authorities that he went into a rage and strangled his wife and smothered his daughters and dumped the bodies at a remote oil site to the north of Denver. He buried Shanann in a shallow grave and put the bodies of his daughters into oil tanks.

The authorities also believe that Watts killed his family on August 13 after security footage from a neighbor's surveillance camera shows him backing up his truck into the garage at 5:30 a.m.

The attorney said that Watts drove the two young children to the oil field in Weld Coun

ty, which was about a 45-minute drive away from their home, with his dead wife's body in the truck. He then brutally smothered Celeste with her favorite blanket while her horrified older sister watched. Describing Bella's last words to her father, Lambert said: "He walks over and takes CeCe's, Celeste's, favorite blanket and smothers her. And at that point Bella said, 'Please, daddy. Do not do to me what you just did to CeCe'. And then he killed Bella." 

Part 2 of the exclusive interview is scheduled to air on March 11.
