UPDATE: Body found floating in Rock River

Janesville Police are investigating the discovery of a body in the Rock River just west of the Monterey Dam.  Police went to the area a little before 5:00 p.m. Friday afternoon on a report of a body in the water.  A 15-year-old boy had been fishing west of the dam and reported seeing pants and shoes in the river.  Authorities found the body about 15-to-20 feet from short.  Janesville Fire fighters helped recover the body, which is described as being of a woman over 60.   Police say the body has no obvious signs of trauma, and an autopsy is planned Saturday to make a positive identification.  The family of a missing Janesville woman, 75-year-old Mary Coulthard, has been notified of the discovery, but police say that does not mean it is Coulthard.
