HIGHLANDS RANCH, Colo. -- A mother and her teenaged son are dead in Highlands Ranch after what the Douglas County Sheriff’s Office said could be the result of a murder/suicide.
Another relative was injured after jumping out a window to escape the violence.
At about 7:30 p.m., deputies were called out to 520 Fox Hunt Circle, near South Broadway and Northridge, on a report of a shooting.
“I just pulled up to the driveway and heard screaming out here. Julia, the neighbor, was in trouble,” said Craig Wilkening, who lives next door.
He found 22-year-old Julia Klamo injured from jumping out a second-story window.
“I wanted to help out and get her out of the situation, if it was dangerous, if it was possible. She couldn’t move. She was pretty much immobile,” said Wilkening.
She told Wilkening her younger brother, Robert Klamo, was coming after her.
“It’s a little nerve wracking when you don’t know what’s going on and there’s an armed person and I’m unarmed,” said Wilkening.
The Douglas County SWAT team responded to the violence as well.
Wilkening said officers help another teenage sister escape from the window with a ladder.
Negotiators tried making contact with the middle-school suspect.
Two-and-a-half hours later, officers burst inside the home to find Robert Klamo and his mother, Tatiana Klamo, 46, dead.
“We believe right now this a murder/suicide," said DCSO undersheriff Tony Spurlock. "The investigation is ongoing, we have no idea what the motive is."
Tatiana was part owner of the American Stitch Company on South Broadway.
The business was closed today because of her death.
Those who knew her said she worked hard to make a good life for her four children, while still going to school -- it’s ambition now gone and a family is torn apart by violence.
“It’s sad. It’s tragic,” said Wilkening. "I feel bad about it."
Two sources said Tatiana told them her son battled mental illness, like his father.
Tatiana’s husband reportedly killed himself more than 10 years ago.
