Springfield fire officials say a suspicious substance that spilled from an envelope in a state office mailroom turns out to be baby powder. But the contents of a letter in that same envelope prompted authorities to treat the incident as a "legitimate threat" intended to strike fear into people, and the incident will be referred to law enforcement as a potential criminal case.
Workers in the mailroom at the Governor’s Office of Constituent Services at College and Monroe downtown were segregated from other employees while the substance was tested. Fire chief Ken Fustin says no one showed any symptoms and no one was harmed.
Fustin would not disclose the contents of the letter that prompted authorities to raise the threat level of the incident. He says there did not appear to be a return address on the envelope.
