Police said they believe a shooting at a northern New York hospital may have narrowly been avoided after a disgruntled former employee was pulled over with a loaded semi-automatic shotgun blocks away from the facility. Robert Thibodeau was arrested Tuesday morning after police in Plattsburgh stopped his pickup truck and found the 12-gauge shotgun with two 10-round magazines and a box of ammunition. Officials say the stop was made after a brother told police that Thibodeau had recently been fired from Champlain Valley Physicians Hospital in Plattsburgh and made comments about returning there to harm people. A lawyer for Thibodeau had no comment.
