(Undated) -- Tests on a suspicious powder sent to several locations near the site of the Super Bowl are coming back normal. Reports indicate at least some of it may be corn starch. One suspicious envelope which turned out to be harmless was sent to the offices of former New York City Mayor Rudy Giuliani. Hazmat teams are still working at several hotels in and around New York City and New Jersey as the investigation continues. The FBI is taking the lead on the case.
