Construction boss charged with killing 20-year-old Kaylin Gillis had ‘short fuse,’ raged about trespassers: neighbor

The upstate New York construction boss accused of gunning down a 20-year-old woman has been described by a neighbor as a “narcissist” with a “short fuse” who would constantly rage about people mistaking his driveway for a road.

Kevin Monahan, 65, has been charged with second-degree murder after he allegedly fatally shot Kaylin Gillis when the car she was in accidentally drove up his Hebron driveway Saturday night while looking for a friend’s house.
