The hours-long standoff began at 12:15 p.m. after George Bateman, 60, of Southeast, N.Y., called his life insurance agent to express suicidal thoughts and threaten to use violence against any police officers who came to his house, Putnam County Sheriff Donald Smith said in a news release. A short time later, a state police remote-controlled robot was sent inside the house, where it was discovered that Bateman had killed himself with a firearm, authorities said.
