Authorities found a truck used by a suspect in the shooting deaths of four people at a bar, the bartender and three patrons, in a small town in western Montana.

The search for the suspect, identified as Michael Paul Brown, continued into the weekend. Authorities have warned that he is armed and dangerous.

A shooting at a Montana bar left four people dead Friday, prompting a lockdown in a neighborhood several miles away as authorities searched for the suspect in a wooded, mountainous area. The shooting happened around 10:30 a.
