(AP) – The search for a former U.S. soldier suspected of killing four people at a bar in Montana stretched into a fifth day, with deputies scouring the mountainous terrain by foot and air after the man escaped in a stolen vehicle containing camping gear.

Authorities say Michael Paul Brown, 45, fatally shot four people Friday morning at The Owl Bar in the small town of Anaconda with a rifle that police believe was his personal weapon. He fled in a white pickup that he later ditched and stole another white vehicle stocked with clothes, shoes and other supplies.

A female bartender and three male patrons were killed. The shooting rattled the tight-knit town of about 9,000 people, and many residents remain on high alert with the suspect still at large.

Here's what is known about the search.
