The man accused of killed four people at a Montana bar on Friday morning lived next door to it, according to the Montana Department of Justice.

Montana Division of Criminal Investigation administrator Lee Johnson says 45-year-old Michael Paul Brown fled The Owl Bar after the Friday shooting in the small town of Anaconda.

Michael Paul Brown, the man suspected of fatally shooting four people at The Owl Bar in Montana, remains at large and is “believed to be armed and extremely dangerous,” authorities said.
