DENVER — A Jefferson County woman was killed and her son was injured when their two dogs attacked them.

The Denver Post reports ( ) the sheriff’s office received a 911 call about the attack Monday night, and deputies found 60-year-old Susan Shawl and her son at their Conifer home.

The woman died at the scene, and 36-year-old Richard Shawl was taken to the hospital with non-life-threatening injuries. Sheriff’s office spokeswoman Dionne Waugh says the mother and son were attacked by their two terrier-pit bull mix dogs.

In 2008, deputies issued Richard Shawl a warning after a neighbor reported the dogs were loose and being aggressive. Investigators said Tuesday they weren’t sure what prompted the mauling.

Richard Shawl has given animal control officials permission to euthanize the dogs.
