A 20-year-old sexual assault victim was saved by two nearby construction workers Tuesday in Madison. The woman was walking at about 11:45 A-M when she was attacked by a man later identified as Kevin E. Kiernan. She says she started yelling for help when he groped her and started to drop his pants. The construction workers saw what was happened and they ran over to help. The 32-year-old suspect was found by police and taken into custody.
