Police are looking for Michael Paul Brown, 45, after four people were shot and killed in The Owl Bar in the small town of Anaconda, Montana.

As the search for Michael Brown enters its sixth day, a local outdoor expert describes the challenging wilderness terrain that's complicating the manhunt for the suspect in the Anaconda bar shooting.

The manhunt in Montana is on day 5 for a former U.S. Army soldier on the run days after he allegedly shot and killed four at a local bar in the southwest part of the Treasure State.
