WELD COUNTY, Colo. – New documents are shedding light on Christopher Watts, the Colorado man who will spend the rest of his life in prison for the murders of his pregnant wife and their two young daughters. In response to a Colorado Criminal Justice Records request, CBS Denver received more than 2,000 pages of documents from the Weld County District Attorney in the case.

Watts killed his wife, Shanann and their two daughters, Bella and Celeste in August. He pleaded for their safe return, but was arrested days later.

On Nov. 6, Watts pleaded guilty to the nine charges he faced, including five counts of first-degree murder. In addition to the murder charges for Shanann and his daughters, he also pleaded guilty to two counts of murdering a child, one count of unlawful termination of a pregnancy and three counts of tampering with a deceased human body.

1540 hours: Shanann began filming in the kitchen of 2825 Saratoga Trail. she stepped in front of the camera briefly to show off her shirt with the embossed words, "Oops… we did it again." When she stepped out of the camera's view Dieter (the family dog) ran off to welcome Watts entering the home. As Watts walked into the kitchen, he halted mid stride and stared in Shanann's direction. His confused expression transformed into a grin and he walked to her saying, "We did it again." When Watts returned in view of the camera he is holding a pregnancy test and they discuss the positive result. Watts leaned in, kissed Shanann and, with a large grin, says, "l guess when you want to, it happens – Wow." Seventy six days later Shanann, her unborn child, Bello and Celeste were murdered *

In an interview with Thornton Police, Watts' alleged mistress Nichol Kessinger said from her perspective, Chris and Shanann "did not get along well and their financial life was also troubling. She said Chris was struggling with finances and now he had a third kid on the way and she does not know if he could afford another kid. Shanann was not responsive to this financial trouble. Nichol said Chris always told her he wanted a third child and wanted a boy."

Kessinger told police she does not think she is the only catalyst for the sequence of events. She does, however, believe that being in Chris's life may have "accelerated the process." She feels "money is the biggest catalyst for this event happening."

In that same interview, Kessinger said she could not think of a reason for why Chris would have hurt his children. She continues, "The only thing she could think of was that the kids may have seen him killing Shanann so he chose to kill them as well."

I missed the smell of you, you touching me when l'm cooking, you touching me in bed, you touching me period! I missed holding you and snuggling with you. I missed eating with you, watching tv with you. I missed staring at you, I missed making love with you. I missed everything about you. I couldn't wait to touch you, hold you, kiss you, make love to you, smell you, laugh with you. I couldn't wait to celebrate 8 years with you… lf you are done, don't love me, don't want to work this out, not happy anymore and only staying because of kids, I NEED you to tell me."

You should also say you don't appreciate her saying they have to learn they can't always get what they want! (Referring to ice cream) they are 2 and 4!

You don't consider others at all, nor think about others feelings." Watts replied that he was sorry and he loves her. Shanann responded, "l try to give you space, but while you are working and living the bachelor life l'm carrying our 3rd and fighting with our two kids daily and trying to work and make money. lt's not hard texting love you and miss you. lf you don't mean it then I get it, but we need to talk. I kept looking at my phone all night and no response from you. Like seriously! We didn't just start dating yesterday! We've been together 8 years and have 2.5 kids together."

In a phone search conducted by authorities, investigators found searches on Kessinger's phone for sexual videos and positions, hours' worth of searches for "Shanann Watts," searches including "can cops trace text messages" after the murders, searches for Amber Frey (the mistress of convicted murderer Scott Peterson), if "people hate Amber Frey," and Frey's subsequent book deal.
