Christopher Watts repeatedly denied murdering his family during voluntary polygraph

Chris Watts repeatedly denied murdering his family during a voluntary polygraph, but finally confessed he was ‘not a good man’ and dumped his daughters’ bodies in a ‘freakin’ oil tank’ when told he had failed the test.

Watts, 33, was sentenced to life in prison on Monday for murdering his pregnant wife and their children at an emotional court hearing where he finally said sorry for the unthinkable killings.

He was given three life sentences without parole for the murders of his 34-year-old wife Shanann, their daughters Bella, four, and Celeste, three, and for killing his wife’s unborn baby son, Nico.

It was the first time prosecutors confirmed his motive: to begin a new life with his girlfriend he had been seeing for two months before he carried out the murders.

Watts killed his wife and children on August 13 in the early hours of the morning.

Their bodies were found on August 16 after Watts went on television pretending not to know what had happened to his family.

Documents from Frederick Police Department show that Watts  had voluntarily consented to a polygraph interview on August 15, which had showed ‘deception indicated’ when asked if he harmed his family.

The documents obtained by Dailymail.com reveal that Watts only confessed to killing Shannan by strangulation after investigating officers informed him that he had failed the polygraph test.

Bizarrely, he maintained that he killed Shannan in response to seeing her ‘on top of Cece’ as she had killed their two children. He claimed: ‘She hurt them. And then I freaked out and hurt her’.

Officers allowed Watts’ father Ronnie to speak to him during the interview when he finally admitted that he ‘was not a good man’ and ‘had a lot of rage’ because Shannan allegedly hurt the girls.

He admitted that he dumped his daughters bodies in crude oil tanks and buried Shannon, who was 15 weeks pregnant with their only son, in a shallow grave at a site near his workplace.

When Ronnie asked where the girls were, Chris broke down and said: ‘That – that’s what I feel horrible about….they’re in a freakin’ oil tank… I didn’t know what else to do.

‘Please, God forgive me for everything. I’m not a good man’. 

Chris also told officers and his father who was present that Shannan hurt the girls because he and other members of his family believed that she was ‘unstable, a narcissist and bipolar’.

Asked what made her ‘snap’,  Chris said he believed it was finding out he was having an affair even though he had not admitted his infidelity to her.

Prosecutors say Watts wanted to start a new life with his mistress

During the trial that investigators found no evidence that Shannan hurt the children and said Chris had killed all of the family members himself.

He then loaded their bodies into his truck and drove to the field where he pushed Bella and Celeste through eight-inch holes which led to separate crude oil tanks.

Bella’s body was scratched as she was shoved through the hole, Rourke said, and a piece of her blonde hair was found on the door.

Watts then stayed at the work site and behaved normally as co-workers showed up for the day. 

Later, when they were all reported missing, he said they were all asleep when he left for work that morning.

Chris said: ‘They’re gone, there’s no bringing them back’ when investigators asked if the girls were still alive during the interview.

Asked why he dumped the bodies at the site, Chris replied: ‘I didn’t know what to do, I didn’t know what to f******g do, like none, none of this made sense… why would she hurt my f*****g girls?’. 

Chris also told investigating officers that everyone knew he was a good man and when finding out that he had killed his wife and buried their bodies, they would say: ‘What the f**k did you do Chris? Why didn’t you just tell the cops to begin with?’.

He claimed the girls were still wearing nightgowns and and were inside 20 foot tanks which contained a mixture of oil and water.

His wife Shannan was wearing just a black or grey t-shirt and underwear when he buried her at another location.

Watts also spoke about his mistress Nikki Kissenger and that he had fallen out of love with his wife because he had fallen in love with her.

Later on in the interview, Chris admitted to officers that he was having an affair with Kessenger and that she took his breath away, claiming he never felt the same way about anyone as he did about her.

He told officers: ‘I cheated on her, im not proud of it… she accused me of it.. and I feel horrible for it…. She was pregnant… I didn’t hurt her… I cheated on her…I hurt her emotionally’.

Chris had told Kessenger he was going to separate from his wife eventually but ‘didn’t know what it was going to look like’. 

He was scared to tell Kessenger about the pregnancy because he felt like she wouldn’t have gone on a date with him if she knew.

When asked if he was sorry for what he did, Chris responded: ‘I wish I wouldn’t have lost control and got on top of Shannan and did that… and then I did that’, referring to dumping their bodies at the oil well site.

He said in July when the couple had visited Shannan’s family in North Carolina , he told her he didn’t feel the same connection with her anymore and suggested that they separate.

He told Shannan there was no one else. ‘This isn’t like somebody came into my life and took me from you,… there’s no outside influence coming from this’. 

The documents also detailed the couple’s financial woes and he suggested selling the house and splitting the proceeds in half when they separated.

They had filed for bankruptcy two years previously and he knew when the the children returned they would be living pay check to paycheck.

Shannon took out $10,000 from their savings account to catch up on their mortgage payments. He believed the loan was taken out five months before their deaths.

They were three months behind on mortgage payment. Chris said he and Shannon were stressed about their financial situation and almost all of their credit cards were maxed out.

Weld County District Attorney Michael Rourke described for the first time how Watts attacked his wife on August 13 after she returned in the early hours of the morning from a business trip.

He had been having an affair and she was desperate for their marriage to survive.

He strangled her calmly, Rourke said, and had no defensive wounds afterwards.

His motive for killing them, Rourke said, was to start a new life with his mistress Nichol Kessinger.

‘He had a desire for a fresh start.

‘To begin a relationship with a new love that overpowered all decency and feelings for his wife, his daughters and unborn son.

‘While Shanann texted the defendant over and over again in the days leading up to her death, he secreted photos of his girlfriend into his phone and texted her at all hours of the night.

‘While Shanann sent him self-help and counseling books, he was searching the internet for secluded vacation spots to take his new love and was researching jewelry.

One was to the school where the girls were supposed to start, telling the school that the girls were being un-enrolled.

He also contacted a realtor to start discussing selling his house and he texted with his girlfriend about their future.
