On Wednesday, Leahy was literally caught in the act by State Police Lt. Steven O'Reilly, who had also stopped at the rest area.
"I am used to getting there after something happens, not while something is happening. It affects you a little bit more," O'Reilly said.
"During the time period that he was in the men's room, he heard what he believed to be a scuffle in the adjoining women's room. He went in and arrested the individual who was standing in the bathroom. The scene was blood-smeared. That individual was Mr. Leahy, who is now currently under arrest," district attorney Tim Cruz said.
