Three people found dead inside a suburban Denver home had been shot, authorities said.
The bodies were found this morning in Adams County after a distraught woman called 911 to report a disturbance in the home before hanging up.
Commander Terrance O'Neill, of the Adams County Sheriff's Office, said investigators meticulously searched the house for much of the day.
He said authorities do not know the victims' ages, and he would not say anything else about their identities.
Deputies are looking for a man who was seen leaving the modest, single-level residence in the Westminster area.
Outside the home later today, investigators had placed at least a dozen markers typically used to flag evidence such as bullet casings, in the driveway and street.
