It was supposed to be a fun time, at least that what Homecomings are all about isn't it? But in little Crandon, Wisconsin, where the population doesn't even top 2,000, the fallout from a Homecoming tragedy has left this community silent and confused.

The leaves are changing and there are pumpkins on porches, but today this town mourns the loss of seven of its own. It's seven, because once off-duty deputy sheriff Tyler Peterson had finished murdering his ex-girlfriend and her friends, he was felled by a police sniper.

Peterson had gone to the party, according to residents, and was asked to leave. He returned a short time later with a rifle.  Police say he fired 30 shots, taking the lives of three high school students and three recent grads.

Today investigators are combing through the old white farmhouse where this nightmare took place. They are taking fingerprints, and circling bullet holes just like they do on big city crime shows.

Tyler Peterson  had only been with the Forest County sheriff's department a year, and the town's prosecutor says he came through the course with flying colors.

But that was then. His friends say "something must have snapped." In a town where everyone knows both the victims and the perpetrator, it may never be the same.
