A Bay Area-based staple of the death metal music genre was gunned down by police in South San Francisco Monday, after a dispute with a neighbor over tree clippings turned violent.

Possessed guitar player Brian Montana, 60, was fatally shot by authorities after he brandished a weapon toward his neighbor, authorities with the South San Francisco Police Department confirmed to the San Francisco Chronicle Thursday.

Montana ‘fired multiple times at officers using a handgun, shotgun, and rifle,’ police said of the incident. ‘Officers used patrol cars as cover and returned fire.

The suspect was struck and ultimately pronounced deceased at the scene.’
