Before learning he would never walk out of prison Monday, Chris Watts sat at the defense table, head down and leg bobbing, as his mother told him she loved him and his slain wife's family called him a monster.
Calling it perhaps "the most inhumane and vicious crime that I have handled out of the thousands of cases that I have seen," Judge Marcelo Kopcow handed down five life sentences -- three consecutive and two concurrent -- with no possibility of parole, in the deaths of Watts' daughters and pregnant wife.
Watts also received an additional 48 years for the death of his unborn son, who was to be named Nico Lee, and 36 more years for crimes related to his disposal of the bodies.
His hands were shackled at his waist and Watts wore an orange jumpsuit. He rarely looked up during the proceeding -- not even when his mother turned around to face him and tearfully said, "We have loved you from the beginning and we still love you now."
The only time Watts spoke during the proceeding was when Kopcow asked him if he wished to deliver a statement. "No, sir," the former father replied.
Before Watts was sentenced, Weld County District Attorney Michael Rourke revealed horrific details of how Watts strangled his wife, Shanann, and their daughters, Bella, 4, and Celeste, 3, before crudely disposing of them at a secluded site where he worked.
"The man seated to my right smothered his daughters," Rourke said. "Imagine the horror in Bella's mind as her father snuffed out her life. ... She fought back for her life as her father smothered her."
An attorney for Chris Watts followed Rourke's statement, saying her client is "devastated," and though Watts realizes his words are hollow, he is "sincerely sorry for all of this."
Watts, 33, pleaded guilty this month to first-degree murder and other charges. With approval of his wife's family, prosecutors dropped the possibility of the death penalty.
His sentencing comes days after a woman he had been dating told The Denver Post that he lied to her about being near the end of divorce proceedings. She cooperated with police before his arrest, she told the newspaper.
Plea from front porch
When Shanann Watts and the two girls went missing in mid-August, Chris Watts first told reporters they had gone to a friend's house before later pleading for his family's return in an interview with CNN affiliate KMGH.
"My kids are my life," Watts said, standing on the front porch of their home in Frederick, about 30 miles north of Denver. "Those smiles light up my life."
Watts told the station his wife came home from the airport about 2 a.m., and he left for work about 5:15 a.m. He said the two had an emotional but civil conversation before he left, but he didn't elaborate.
Separately, he told law enforcement that on the morning of August 13, before leaving for work, he had informed his wife that he wanted a separation. They had not argued, but they were both upset and crying, he told police, according to an affidavit.
Chris Watts claimed he had called and texted his wife about three times that morning with no reply, he told KMGH. He said he realized something was wrong when Shanann Watts' friend arrived at the couple's home around noon.
"She just got back from Arizona, and I figured she was just busy, but when her friend showed up, that's when it just registered -- like all right, this isn't right," Watts said.
Story doesn't add up
Three days later, Shanann Watts' body, 15 weeks pregnant with their third child, was found in a shallow grave. The bodies of Bella and Celeste were found in commercial oil tanks at a company where Watts had worked.
After authorities found the bodies, Chris Watts changed his story, telling police he had strangled Shanann Watts in a fit of rage after seeing his wife choking Celeste.
On November 6, Watts pleaded guilty to nine charges, including three counts of first-degree murder and unlawful termination of a pregnancy.
Authorities aren't sure why he killed his family.
After the plea deal was announced, Weld County District Attorney Michael Rourke told reporters that authorities have a partial motive. He would offer more thoughts after Watts is sentenced, he said.
Other woman tells her side of story
According to an unsealed Weld County arrest affidavit, investigators say they discovered Watts was "actively involved" in an affair with a co-worker.
It's not clear if that was Nichol Kessinger, 30, who told The Denver Post she met him while working for the environmental department of a petroleum contractor.
"We had just met," Kessinger told the newspaper. "I barely knew him."
He wasn't wearing a wedding ring when they were introduced, and she thought he was attractive, soft-spoken and a good listener, she said. When they first met outside of work in late June, he told her he was in the final stages of a divorce. She never met any of his relatives or friends, Kessinger told The Post.
Watts sent her a text August 13 to say his family had disappeared, and she was confused about why the media was at his house.
"When I read the news, I found out he was still married and his wife was 15 weeks pregnant," Kessinger told the newspaper.
She peppered him with questions via phone calls and text, she said, and he changed his story about the divorce, showed little emotion about his family's disappearance, and tried to change the subject.
"It got to a point that he was telling me so many lies that I eventually told him that I did not want to speak to him again until his family was found," she told the paper, explaining that she called police on August 15 to report Watts' lies.
