The body of a woman was found near a brook yesterday, and police said she may have died several weeks ago. Officers went to Smith Lane at about 2:50 p.m., after a man reported finding the body by a steep embankment. The woman has not been identified, police said, and authorities have not determined a cause of death. An autopsy is scheduled for today, and police have not ruled out foul play. Further information was not immediately available last night.
