A loud noise rattled more than 100 people attending a candlelight vigil Saturday outside the headquarters of Rep. Gabrielle Giffords, where authorities investigated a suspicious package that turned out to be non-explosive.
Police department spokesman Lt. Fabian Pacheco says an officer checking Giffords' office in Tucson had found a "strange" item that he said resembled a coffee can and had writing on it. Pacheco would not disclose what the writing said. Pacheco says there was no threat to public safety. (AP)
