Multiple high-ranking law enforcement sources reportedly told the Denver Channel that investigators found the bodies of Celeste and Bella Watts, the three- and four-year-old daughters of Shannan Watts, who is also presumed dead.
According to the report, the bodies of the little girls were found inside oil and gas tanks on the property of Anadarko Petroleum, where Shanann Watts’s husband Chris Watts was employed until this week. On Thursday, investigators found a body on the same property they believe is Shanann Watts, though the remains are still pending identification.
Law enforcement sources reportedly told the Denver Channel that authorities believe Watts hid the bodies there in part to mask the smell of the remains.
