Christopher Watts provided local, state and federal investigators with more details about the murders of his wife, Shanann, and his daughters, Bella and Celeste, in interviews at the Wisconsin prison where he is being held, which were conducted last week.

The Colorado Bureau of Investigation said Thursday that investigators from CBI, the Federal Bureau of Investigation and the Frederick Police Department met with Watts on Feb. 18 “for the purpose of developing further insight into the case.”

Prison visitation records show that three investigators visited with Watts starting just after 8:30 a.m. that day.

The CBI says that an audio recording of the interview and a written report would be released next Thursday, March 7 via the Colorado Open Records Act for those who have requested the files.

Though the release from CBI Thursday did not disclose any further details about what Watts unveiled in the interview, the Greeley Tribune reports, citing sources close to the investigation, that Watts told investigators how and why he murdered his family – something he himself had not outright discussed previously.
