JEFFERSON COUNTY, Colo. - A 25-year-old man shot and killed his stepmother and wounded his father before taking his own life during a Monday night argument at the family's Indian Hills home, the Jefferson County Sheriff's Office said Wednesday.
Deputies responded to the home at 23038 Pawnee Rd. at 10:05 p.m. after receiving a call from 24-year-old Sarah McConaghie. She said she had heard gunfire from the main level of the family home after her stepbrother had an argument with her parents, according to the sheriff's office.
A dispatcher radioed deputies that McConaghie said her stepbrother "has started shooting" and she heard her parents screaming and had locked herself in her bedroom, according to a recording of radio traffic provided by RadioReference.com.
McConaghie, who was calling from a closet in her bedroom, remained hidden and on the phone with dispatchers until deputies arrived on scene.
Deputies entered the home through an unlocked rear door and soon found three people on the main floor who had been shot.
The mother, 53-year-old Margaret Leiman, and her stepson, 25-year-old Robert Leiman, were both pronounced dead at the scene, sheriff's officials said. The father, 58-year-old Bruce Leiman, was transported by air-ambulance to Swedish Hospital. He was in stable condition on Tuesday night.
Deputies found McConaghie hidden the closet and escorted her from the home.
The handgun used in the shooting belonged to Robert Leiman, sheriff's officials said.
"The preliminary investigation indicates that during an argument between Robert and his parents, he went to his room to retrieve a handgun, returned to the main level of the home and shot both Margaret and Bruce multiple times," sheriff's officials said. "Robert then fired several shots into the room where Sarah was and then returned to the main floor where he shot himself."
An autopsy showed Margaret Leiman died from multiple gunshot wounds, and Robert Leiman died from a self-inflicted gunshot wound, according to the Jefferson County Coroner's Office.
