The search for the suspect continued in the mountains just west of Anaconda, where he is accused of fatally shooting four people, officials said.

Michael Paul Brown, 45, fled The Owl Bar in the small town of Anaconda in a white pickup truck but ditched it at some point, officials said.

Police have found the getaway car of a US military veteran who walked into a bar in the western state of Montana on Friday morning and fatally shot four people, but the gunman remains at large.
