"It was just a surprise. It's one of those 'this doesn't happen here' kind of things. It's actually a grim reminder to us all that we're all vulnerable," he said.

Was it a drug deal gone bad? A theft? A fight? Residents want to know, but authorities refuse to speculate.
Casey Cox, the sheriff department's lead investigator, explained that officials want to be careful about what they release, while acknowledging that this case is personal to many: "There's a lot of emotion that goes into this case just simply based on the age of these children."
