Officials are praising the response to a shooting that wounded two people who were leaving a high school prom in northern Wisconsin.

Police say 18-year-old Jakob E. Wagner wounded two prom-goers outside the school Saturday night before he was killed by police.

Investigators have not discussed a possible motive. But the interim district administrator said it appeared Wagner intended to go into the dance and start shooting randomly.

Gov. Scott Walker says in a statement that the actions of the Antigo Police Department "undoubtedly saved lives."

The Unified School District of Antigo says the "quick actions" taken by police and district staff to secure the building "prevented what might have otherwise been a disaster of unimaginable proportions."
