Coroner: Highlands Ranch teen Robert Klamo killed mom, Tatiana Klamo, then himself

2 siblings escaped home, one injured in fall

HIGHLANDS RANCH, Colo. - The Douglas County Coroner’s Office has confirmed a 15-year-old boy killed his mother, then himself, in a Highlands Ranch home on Friday night. Two of his siblings escaped the home, but one was seriously injured when she fell off the roof.

Deputies and ambulances were called to the home near Fox Hunt Circle and Old Stone Drive around 8 p.m. on a report of a shooting.

The Coroner's Office said Tatiana Klamo, 46, of Highlands Ranch, died from multiple gunshot wounds.

Klamo's business partner, Brian McCoy, told 7NEWS that Klamo's 15-year-old son had a mental illness and was fighting with his mother over not wanting to take his medication.

"She was actually going to send him back to the hospital," McCoy said. "She was afraid all the time."

During the argument, Klamo's two daughters escaped from windows.

McCoy said one girl jumped from a window and was physically OK. However, a second daughter fell and broke her back, McCoy said.

Deputies surrounded the home and tried to communicate with the teen, but got no response, according to the Denver Post.

Deputies sent a robot in to search the home and apparently found Klamo's son, Robert, dead.

The coroner said Robert Klamo died from a single gunshot wound and confirmed his death was a suicide.

McCoy said Tatiana Klamo loved "the heck out of" her son.

"This is just a tragic end," McCoy said. "She’s been going to grad school learning about mental illness and criminal justice so she could help families with problems like hers because she thought she was a success story."
