A Minnesota teenager was killed and four others were injured after a man engaged in a series of stab wounds near a Wisconsin river during a day of tubing.
The suspect, a 52-year-old man, was arrested about 90 minutes after Saturday’s attack in Apple River, St. Croix County Sheriff Scott Knudson said at a news conference.
Investigators believe the victims and the suspect were tubing in the river in separate groups before the stabbings.
“At this time, we don’t know what triggered this incident,” Knudson told reporters Saturday night.
The 17-year-old boy was rushed to an area hospital, where he was pronounced dead. The other victims – a woman and three men – are in their early 20s, the sheriff said. Most of the injuries sustained were to the torso, he said.
A photograph taken of the suspect by a witness helped authorities track him down, Knudson said. The knife used in the attack was not found on Saturday evening.
“It’s been several years since a stabbing happened, maybe 15 years now,” Knudson said of the area.
“I’m sure anyone who witnessed this will never forget it,” he added. “So it’s a tragedy.”
The victims and the suspect were not immediately identified.
No charges have been announced, but could be confirmed by Monday. Authorities were continuing their investigation on Saturday evening, Knudson said.
“We’re trying to divert some of the tube traffic around our crime scene so that on its own will cause problems, trying to get them out of the river, gathering what we can in a hard-to-reach area,” Knudson said.
