Chris Watts pleaded guilty to the August 2018 murders and is now serving five life sentences without the possibility of parole
Chris Watts — the Colorado man who strangled his pregnant wife and smothered their two daughters last August — has provided more details about his crimes to investigators.
A statement to PEOPLE from the Colorado Bureau of Investigation confirms authorities met with Watts, 33, on February 18. Officials from the Federal Bureau of Investigation and the Frederick Police Department were also present.
Investigators “interviewed Christopher Watts for the purpose of developing further insight into the case,” the statement reads.
“Watts provided investigators with additional information about the murders of Shanann, Bella, and Celeste during the interview,” it continues.
The CBI prepared a report on the interview, which will be released to the media next week.
Watts is currently serving five life sentences without the possibility of parole for the Aug. 13, 2018 killings of 34-year-old Shanann, who was 15 weeks pregnant with their son, Niko, and their daughters Bella, 4, and 3-year-old Celeste.
The killings occurred the day Shanann returned from a weekend work trip in Arizona.
In November, he pleaded guilty to all three killings.
After his wife and kids were dead, Watts loaded their bodies into his truck and hid them on an oil work site where they were found three days later.
Watts was having an affair with a co-worker at the time of the killings. Authorities have cited his desire for a “fresh start” with his mistress as his motive for the killings.
