A Concord man has been accused in court documents of calling his alleged victim 523 times in two days. Sheldon Bunnell, 41, pleaded not guilty in Essex Superior Court on Monday to 11 new criminal charges including drunken driving – third offense, domestic assault, careless and negligent operation of a motor vehicle and eight counts of violating conditions of release. Bunnell is also accused of assaulting the alleged victim leaving her with a bruise over her right eye. Essex County State’s Attorney Vince Illuzzi said each one of the calls Bunnell is accused of making is a violation of his conditions and he convinced Judge Justin Jiron that the court should set additional conditions of release and $1,000 bail. Police say that when they interviewed the alleged victim in the case she told them Bunnell just kept calling her even though he had previously been ordered by Judge Jiron to not contact, abuse or harass her. Bunnell, who is now being held in pre-trial detention at Northeast Correctional Complex in St. Johnsbury, is facing a possible sentence of up to ten years in prison and $11,500 in fines.
