GARDINER, Mont. -

The Park County Sheriff's Office in southwestern Montana is investigating an apparent murder-suicide in Gardiner.

The Billings Gazette reports (http://bit.ly/O623An) that deputies and Yellowstone National Park rangers responded Thursday to a home after a woman reported a man had shot at her and was trying to break in.

Authorities say they found the man dead and a woman still alive but who died at the scene.

Authorities identified them Friday as 63-year-old Steve A. Cole and 59-year-old Debi J. Roberts.

Undersheriff Scott Hamilton says autopsies are planned in Bozeman. He didn't provide a possible cause of death.

Authorities say Cole and Roberts had previously been in a relationship, and that Cole had a previous charge of domestic violence.
