A 26-year-old Fond du Lac man was flown to Theda Care Medical Center in critical condition. A 17-year-old Fond du Lac girl was brought to St. Agnes Hospital in serious condition and later transferred to Children's Hospital in Milwaukee.
A 2-block area was blocked off around the apartments as police searched for possible suspects.
At this point in the investigation, no suspects have been identified. Investigators don't believe this was a random act.
