A man charged with second-degree murder for shooting a 20-year-old woman after the vehicle she was in took a wrong turn into an upstate New York driveway was known for his bitterness towards people driving onto his property by mistake, according to a neighbor. 

Kaylin Gillis and her friends mistakenly drove onto the property of Kevin Monahan on Saturday night in the rural town of Hebron, when Monahan opened fire at their vehicles as they tried to turn around and killed Gillis, Washington County Sheriff Jeffrey Murphy said.

“While they were leaving the residence once they determined that they were at the wrong house, the subject came out on his porch for whatever reason and fired two shots, one of which struck the vehicle that Kaylin was in,” Murphy said during a news conference Monday.

Monahan was then arrested on a second-degree murder charge and remains detained pending a bond hearing. 

Gillis’ death, which happened just days after 16-year-old Ralph Yarl was shot and wounded in Kansas City, Missouri, when going to the wrong house to pick up his younger brothers, has renewed national debates on “stand your ground” laws. Such laws govern the use of deadly force in self-defense. 

On Tuesday, Monahan’s attorney spoke out for the first time on the incident, calling the sheriff’s version of the events a “superficial, simplistic” account of what actually happened.
