The mother of a nine-year-old girl , who drowned in the Rock River near Angler’s Park June 25th, has filed a $500 thousand claim against the city of Janesville.  The city council will consider the claim during its regular meeting Monday.  Madison Billups’ mother, Simone Harris contends the city failed in its duty to protect residents from the river’s dangers.  The claim includes allegations the city did not post signs notifying the public of the dangerous river access and swift current at Angler’s Park.  Officials say after investigating the incident and talking with the city’s insurance representative, it has been determined the claim should be denied.
