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.

A manhunt is intensifying for the former U.S. Army soldier who's been at large for days after allegedly gunning down four people at a Montana bar.

Four people were killed in a shooting at a bar in Anaconda, Montana, on Friday, authorities said. A suspect is at large.
