By the time the gunman shot himself, Jonathan Stoffel, 33, of Neenah, and his 11-year-old daughter, Olivia Stoffel, were dead in what police called a random attack. Stoffel's wife, Erin Stoffel, 32, was struck three times but survived, guiding her other two children, ages 5 and 7, off the bridge and sending the older one for help.
