Police are continuing their search in the area where the vehicle of a Gardner man suspected of murder was found.
Aaron Pennington is wanted in the shooting death of his wife Breanne, which occurred last weekend.
A hunter discovered the 33-year-old Pennington's car near Camp Collier, a scout camp in the Gardener area on Sunday.
Authorities are asking operators of cameras, either at their homes or on trails to check their content and report anything suspicious to police.
Pennington is to be considered armed and dangerous.
