TEWKSBURY, Mass. (AP) — State police are warning Tewksbury residents of someone going door-to-door claiming to be part of a police organization collecting money for the children of a state trooper who was killed in a crash.

Police on Wednesday said neither the Massachusetts State Police nor any other police organization is going door-to-door to collect donations for Trooper Thomas Clardy.

The two official funds set up for Clardy are The Clardy Children's Fund and The Greg Hill Foundation.

The 44-year-old Clardy was a Marine Corps veteran and father of seven.

Clardy had stopped a car for a traffic violation in Charlton on March 16 when his cruiser was hit by another vehicle.

Clary was laid to rest Tuesday in his hometown of Hudson.
