A 55-year-old Sutton man was fatally injured while working construction at a Concord school on Wednesday afternoon, according to the Middlesex District Attorney’s office.
The man was operating a flatbed truck with an attached crane on the grounds of the Willard School on Powder Mill Road when the incident occurred around 2 p.m. officials said.
A preliminary investigation suggests the man was operating the crane outside of the vehicle “when an apparent mechanical failure occurred,” officials said.
The man — who has not been identified — was struck by the construction equipment and was pronounced dead at the scene, according to officials. The investigation into the accident continues.
