A New Hampshire police chief who was killed in the line of duty was honored with a Medal of Valor at an annual gathering of New England law enforcement officers. Michael Maloney, the police chief in Greenland, was killed in April when he and several other officers came under fire while carrying out a search warrant. Four other officers were injured. On Wednesday, his father, John Maloney, accepted the medal from the New England Association of Chiefs of Police. The award is given to one police officer in New England every year. WMUR-TV reported that members of the association said they chose Maloney because of his heroic actions when he and several other officers came under fire.
