Jeff Sanders, a next-door neighbor for more than 15 years, said he heard only a faint dog bark as he got up for work, only to see police and emergency vehicles arriving, and paramedics tending to the shooter's wife.
"It's like a bad dream," Sanders said.
Linda Behrhorst, who lives across the street, was among those who knew the family and described their children as polite and successful.
"Those kids were the most wonderful kids you would ever want," Behrhorst said. "Why anyone would hurt them is unbelievable."
The family had celebratedLaurin Edwards' birthday on Wednesday and Sanders, who spoke with her father that night, said, "Everything seemed fine."
