The attack happened late Saturday outside the Antigo High School prom, said Eric Roller, the chief of police in Antigo, a community of about 8,000 people roughly 180 miles north of Milwaukee. Roller told reporters that the gunman shot the two students as they exited the building, though he didn't say if investigators believe they were specifically targeted or discuss a possible motive for the attack. "Officers were in the parking lot patrolling the activities and heard the shots and an officer immediately fired upon the shooter, stopping the threat," he said in a statement, per CNN. He said the gunman was then taken into custody. Authorities said the two students and the attacker were taken to a hospital and that investigators don't believe there is a further threat to the community. Langlade County Coroner Larry Shadick told the AP that the attacker died shortly after 1am in the intensive care unit of a Wausau hospital. Authorities haven't disclosed the identities of the wounded students or the attacker, but he said the victims' families had been contacted. After the attack, students were escorted from the prom to safety.
