New details emerge in deadly shooting of 20-year-old woman who went to wrong address in New York

When Kaylin Gillis and her friends took a wrong turn into an upstate New York driveway last weekend, they couldn't have known the property was owned by a man who, according to a neighbor, had grown increasingly bitter over the years at people driving onto his land by mistake.

This time, the error proved fatal. The Hebron landowner, Kevin Monahan, opened fire Saturday night, killing 20-year-old Gillis as she and her friends drove away after turning around in the long dirt driveway, Washington County Sheriff Jeffrey Murphy said.

Monahan, 65, was arrested on a second-degree murder charge and remains detained pending a bond hearing.
