Montana's governor has signed an executive order freeing up more resources for law enforcement officers as they search for a former U.S. soldier suspected in a deadly shooting at a Montana bar last week.

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

Those killed on Friday were a bartender and three patrons, ranging in age from 59 to 74, the authorities said. The suspect fled into the nearby foothills.
