A woman was killed Monday night in a dog attack in Conifer and her son suffered injuries and was taken to a local hospital.

The incident happened at about 7 p.m. when the Jefferson County Sheriff’s Office received a 911 call about the attack, said Dionne Waugh, a sheriff’s office spokeswoman.

Deputies responded to the 31000 block of Black Widow Drive. A woman died at the scene and her son, who is in his late teens or early 20s, was taken to a hospital with non-life-threatening injuries, Waugh said.

The mother and son were attacked by two dogs they own, Waugh said. The sheriff’s office described both dogs as a terrier-pit bull mix.

The victims’ names have not been released.

The dogs are in custody of Jefferson County Animal Control. An investigation is ongoing.
