Janesville police are investigating how a Brodhead man ended up at St. Mary's Hospital around midnight Sunday, with a gunshot wound to the leg. Police say the victim reported he was shot by an unknown assailant near the entrance to the bike trail on North Wright Road at Skyview drive. He simply says the gunman flagged him and a friend down and asked for a ride before shooting from outside the vehicle. The injury is not considered life threatening. Police haven't released any theory on the motive.
