DENVER (AP) - Authorities in Highlands Ranch released the names of the woman and teenage boy killed Friday night.
The Douglas County Coroner's office sayd Robert Klamo, 15, shot his mother, Tatiana Klamo, 46, and then himself.
Authorities are investigating the deaths as a murder-suicide.
Ron Hanavan, a spokesman for the Douglas County Sheriff's Office, says deputies and SWAT team members were called to the home near Northridge Park at about 8 p.m. Friday after a report of a shooting. Authorities say the teenager barricaded himself inside the home, and officers found his and the woman's body when they forced their way inside at about midnight.
It's unclear when the teenager and the woman were shot. Another woman was injured but managed to flee the home after authorities were called.
