A gunman who opened fire Saturday outside of a Wisconsin high school prom, wounding two students, has died, authorities said.
Jakob Wagner, 18, was pronounced dead around 1 a.m. Sunday at a local hospital shortly after police say he shot two students with a rifle as they were exiting Antigo High School.
WSAW-TV identified Wagner as a recent Antigo High School graduate. He is believed to have shot his victims at random.
The Antigo Police Department said officers were patrolling outside the school when they responded to the sound of gunfire around 11 p.m.
One of the officers shot and critically wounded Wagner. The two students suffered wounds to their legs that were not life-threatening, police said.
A female victim was treated and then discharged, while a male victim underwent surgery for his gunshot wound. Their names and ages have not been released as of Sunday afternoon.
"The officer’s immediate response prevented further injuries and possible casualties," the police department said in a release. "The initial investigation and officer response indicate this was a lone shooter and a search warrant is being executed at his residence seeking any additional information pertaining to this incident."
Sonia Reed, whose son was attending the event, said nothing seemed unusual while she was on the campus earlier in the evening, CNN reported, citing local affiliate WSAW.
"I didn't see anything suspicious. I didn't feel any bad vibes. It seemed like it was going to be a normal prom," Reed said.
She estimated that 100 to 120 students were attending the event.
Antigo is located about 80 miles northwest of Green Bay, Wisconsin.
