"Residents of the area have been notified and are encouraged to stay inside heir homes and on high alert," Johnson said. Authorities haven't said what led up to the shooting at the bar or a possible motive. Police have identified the four people killed but are not yet releasing their names until they've have had a chance to talk to family members,

Four people were killed in a shooting at a Montana bar and law enforcement are searching for a suspect described by his niece as a former U.S. soldier who struggled to get help for mental health probl

Law enforcement officials engaged in a growing manhunt for the suspect, who lived close to the bar. They warned that he was believed to be armed.
