Shannon Brandt known by neighbors for booze-fueled 'rampages,' being 'nuts his whole life'

GLENFIELD, N.D. – EXCLUSIVE: Neighbors of the North Dakota man who allegedly admitted to mowing down 18-year-old Cayler Ellingson with an SUV describe Shannon Brandt as being "nuts his whole life" and someone who had mental health conditions.
The incident happened early Sunday morning after Brandt, 41, and Ellingson were at a local bar's street dance.
An affidavit states that Brandt told the 911 operator that an individual was threatening him, adding that Ellingson was part of a "Republican extremist group."
Brandt was charged with criminal vehicular homicide, as well as leaving the scene of a crash involving a death after the incident.
