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.

On its Instagram Stories Wednesday, the group Possessed shared an image of the late musician with the caption, ‘Rest In Peace Brian Montana.’ (The outlet Consequence identified the musician as the man on the left in the photo the band posted as tribute.)

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.’

Montana used three firearms to shoot at authorities for about 30 minutes, officials said, according to CBS Bay Area.

Authorities told CBS they reported to the 300 block of Arroyo Drive at around 6 p.m. local time after they received a report of an armed man threatening a neighbor.
