GRAND RAPIDS, Mich. – The Kent County Sheriff says preliminary testing on the powder sent to a Kent County courthouse was not a “biological” agent.
The powder was discovered in an envelope mailed to the 63rd District Courthouse at Knapp Street and the East Beltline Monday morning. The courthouse was closed for about three hours while hazmat crews contained the materials and cleared the building.
Testing is expected to take at least five days to determine what the substance in the envelope was. The Kent County Sheriff says there were able to determine in preliminary testing, that the powder was not a biological agent, like anthrax.
No one was injured and no one has shown any ill-effects from exposure to the powder.
