The manhunt for an Army veteran suspected of killing four people at a bar he frequented has expanded in the rugged Montana terrain, even as some fear the fugitive may return to the area, authorities said.

Montana Govenor Greg Gianforte was slated to hold an updated press conference sometime Tuesday, Aug. 5 to address the manhunt.

The manhunt for the person who opened fire and killed four people at a Montana bar stretched into its fourth day Monday.
