NIAGARA, Wis. — A dragnet ended Friday with the arrest of a man accused of emerging from woods in camouflage and opening fire with an assault rifle on a group of young swimmers who had gathered at a lake. Three were killed and another wounded.
Marinette County Sheriff Jim Kanikula did not immediately release the suspect's name, motive or details of the arrest.
More than 100 law enforcement officers from at least 10 agencies were called in to hunt for the middle-age gunman in Thursday's attack. Authorities had set up roadblocks and evacuated some homes in the northern Wisconsin area just across the state line from Michigan's Upper Peninsula.
Kanikula said there was no communication between the gunman and his victims. The shooter was only 7 to 10 feet away from one victim when he fired on the group of nine young people who had gathered near a railroad bridge on the Menominee River, he said.
"There's a saying up her that this is a great place to raise kids," said Randy Van Gasse, the school superintendent in nearby Norway, Mich., where 17-year-old victim Tiffany Pohlson would have been a senior in the fall.
"That's been violated and we don't know why," he said. "This is obviously a shock to everybody."
The other dead were identified as Anthony Spigarelli, 18; and Bryan Mort, 19. A fourth victim, 20-year-old Daniel Louis Gordon, was wounded. All were also from Michigan.
