Tucson: A loud noise rattled more than 100 people attending a candlelight vigil on Saturday outside the headquarters of Republican 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.
A bomb squad worked for a couple hours, using X-ray equipment, to try to figure out what the package was before the loud noise was heard. The noise was caused by authorities` efforts to destroy the package and render it safe.
Pacheco says there was no threat to public safety.
The package was found after a shooting rampage that left Giffords wounded and killed six others.
