In the early morning hours of that tragic day, Chris strangled his pregnant wife at the family's home in Frederick, Colorado. He then killed their two young girls by suffocation.

Chris, 33 years old at the time, then drove their dead bodies out to an oil storage facility, where he dug a shallow grave for Shanann and put his daughters' bodies into oil tanks.

Before his confession, Chris had reported his wife and kids missing, even giving police permission to search his home, where responding officers found several of Shanann's items, including a cell phone, purse, and medicine. However, there were no signs of them.

Initially, Chris told investigators he was not sure where his wife would be and claimed he last saw her at 5:15 A.M. that morning.

He additionally pleaded for his wife to come home in eerie local news interviews taken from outside their home. The FBI would join the investigation, and after failing a polygraph test, Chris confessed to his father, Ronnie, and then to authorities.

Chris would plead guilty in court and was convicted of nine total charges: five counts of first-degree murder, one count of unlawful termination of a pregnancy, and three counts of tampering with a dead body.

He was sentenced to five life sentences to be served at the Dodge Correctional Institution, a maximum-security prison in Wisconsin.

Seven years after the shocking crime, Chris is said to be filled with regret.

"He's sad that everyone is hurting," a friend, Kim, told People about the killer's mindset. "He wishes he could go back in time. He wishes he had handled things differently."

Despite Kim's comments, previously leaked jailhouse letters written by Chris told another story. In the letters, Chris appeared to blame everyone but himself for his crime, claiming his wife was a "control freak" who didn't give him attention.

He also claimed it was Shanann's fault he was having an affair with his mistress, Nichol Kessinger, whom he branded a "harlot" and an "evil woman" who tempted him with "flattering speech" and "lust in her eyes and flesh."

While a motive has never been confirmed, investigators believe Chris committed the heinous crime to be with Kessiner.
