ANTIGO, Wis. - Authorities have identified a man who they say shot and wounded two students outside of their northern Wisconsin prom as 18-year-old Jakob E. Wagner.

Police say Wagner opened fire late Saturday and shot the male and female students with a rifle as they left the high school dance in Antigo, a community about 150 miles north of Milwaukee.

Police Chief Eric Roller says an officer who was in the parking lot shot Wagner. Langlade County Coroner Larry Shadick told The Associated Press that he died early Sunday morning in the intensive care unit at a Wausau hospital.

School officials in Wisconsin say officers, "prevented what might have otherwise been a disaster of unimaginable proportions."

The district said in a statement that Wagner had approached the school with a high-powered rifle and a large ammunition clip.

Police already were stationed to patrol the parking lot at the high school dance in Antigo, a community about 150 miles north of Milwaukee.

In a news release, police say the female student was treated at a hospital and released and that the male student was undergoing surgery for injuries that weren't life-threatening.

Eighteen-year-old Dylan Dewey of Antigo tells The Associated Press that he and Wagner graduated from Antigo High last year and that Wagner continued to help out at the school in one of the art classes. He also says Wagner had been dating a girl at the school but that she had broken up with him last month.

Dewey described Wagner as an "all-around good guy" and said he generally seemed happy.
