BOULDER COUNTY, Colo. — Three people were found dead in a home in Coal Creek Canyon on Saturday and investigators say the killer is still at large.

On Sunday, the Boulder County Sheriff’s Office said detectives had ruled out the possibility that it was a murder-suicide.

Two men and one woman were found dead in the home in the 800 block of Divide View Drive after a friend requested a welfare check.

The sheriff’s office later identified the victims as 54-year-old Wallace White of Golden, 56-year-old Kelly Sloat-White of Golden and 39-year-old Emory Fraker of Broomfield.

“The man requesting the welfare check was concerned about his friends, as he hadn’t heard from them in several days,” the sheriff’s office said in a statement Saturday afternoon.

It’s not clear when the victims were killed, but a hazardous materials team was called in to confirm the environmental conditions were safe for investigators.

The sheriff’s office said it believes “the residence was specifically targeted” but did not provide any additional details, citing the ongoing investigation. Investigators stated they believe there is not a general threat to the public.

There is a large team working to find whose responsible for the triple homicide.

“There are currently more than 20 investigative personnel assigned to this investigation, which is likely to be lengthy,” the sheriff’s office said.

The sheriff’s office said Saturday there were “indications of trauma” on all three bodies.

On Sunday, the sheriff’s office said it would not release any additional information about the extent of the victims’ injuries while the case was under investigation.

The Boulder County Coroner’s Office typically discloses the cause and manner of the death, but it’s not clear if that will be made public.

Anyone with information is asked to contact the sheriff’s office 303-441-3674, submit a tip by email or call Northern Colorado Crime Stoppers at 800-222-8477.
