The Park County Sheriff's Office is investigating a possible murder-suicide after Park County deputies and Yellowstone Park Rangers responded to a home in Gardiner Thursday afternoon to find one man dead and a woman in critical condition. The woman later died at the scene, according to a press release.
Yellowstone National Park dispatch received a call on Thursday about 4:30 p.m. from a female reporting a man breaking into her home. She reported that the male had already fired shots at her.
The caller reported the man by name. The press release stated that they had previously been in a relationship, according to initial reports.
The man was deceased when officers arrived on the scene, and the woman was in critical condition. Emergency responders tried to save the woman, but she died soon after.
The preliminary findings, according to the press release, indicate a murder-suicide.
The man had a previous charge of domestic violence.
A dispatcher for Park County said more information would be available Friday morning.
An autopsy is also scheduled for Friday.
