SEATTLE (AP) — An FBI agent says the white powder sent in envelopes to eight federal buildings in Washington, Idaho and Utah on Monday was not hazardous.
Special Agent Frederick Gutt says overnight laboratory tests showed that the main component of the powder was calcium carbonate, which is found in chalk.
Gutt says the investigation on who sent the mailings continues. He says that there was a threat associated with the envelopes, but could not disclose more details.
No illnesses were reported from the mailings Monday.
Envelopes were found at a federal building in Seattle, Internal Revenue Service offices in Bellevue, Wash., and an FBI office in Spokane, Wash. In Idaho, the U.S. attorney’s office and an FBI office in Coeur d’Alene, an FBI office in Pocatello and the U.S. attorney’s office in Boise received envelopes.
In Salt Lake City, an FBI office was also targeted.
