The Sheriff of St. Croix Scott Knudson, the victims and the suspect, a 52-year-old Minnesota man, were all in Apple River when the attack happened Saturday afternoon. Knudson said investigators are working to determine what led to the stabbings and whether the victims and the suspect knew each other. They had pipelines with two different groups that included about 20 people. “We don’t yet know who connected with who, who knew each other or what caused it,” Knudson said. The stabbing happened in a remote stretch of the river near the town of Somerset, Wisconsin, which is about 56 kilometers east of Minneapolis. The suspect was apprehended about an hour and a half later while wading down the river. “Thank God a witness took a picture of him,” Knudson told the Minneapolis Star Tribune. “Another witness spotted him at the exit of the tube area, where he was taken into custody.” A 17-year-old boy from Minnesota has died. Two of the other victims were airlifted to a hospital in St. Paul, Minnesota, and two others were taken there by ambulance. All four surviving victims – a woman and three men who are all believed to be in their 20s – were in a critical condition. The names of the victims and the suspect were not immediately released, but St. Louis County Jail records. Croix shows a 52-year-old man was being held without bail on suspicion of first-degree murder, four counts of aggravated assault and four counts of rioting.
