The Pennsylvania man who shot up a women's aerobics class, killing three people and then himself, was questioned a week earlier by police because he matched the description of a man seen pulling what appeared to be a grenade from a computer bag, authorities said today. Police let George Sodini go because they couldn't confirm he was the man spotted.
Questioned about the incident, Sodini denied it, and the witness failed to ID him. "There wasn't much more we could do," says Allegheny County's police superintendent. But after the shooting, investigators found writings in Sodini's home that referenced the incident.
