(NEW YORK) — The Oregon State Police along with other law enforcement agencies are investigating suspicious letters and packages — some containing “an unknown substance” — sent to government offices across the state, the police department said in a statement.
Grant County Sheriff Glenn Palmer was taken to the hospital Monday night after opening up one piece of mail and developing a rash on his arms. But he was released within hours, according to KGW-TV in Portland.
Efforts to reach Palmer were not successful.
The Jackson County Sheriff’s Office, meanwhile, had to be evacuated because of a suspicious package. About 60 people had to leave once it was noticed. At least two county courthouses in the state were also evacuated.
The FBI and U.S. Postal Service are assisting local officials as they work to determine precisely what substance was sent through the mail system, and who sent it. Officials said at least 10 letters appeared to be from the same person.
State officials will likely be testing the substance.
Meanwhile, the state police is urging the public to look out for any mail “that has excessive postage, no return address, excessive tape to secure [it], misspelled words … strange odors, and oily stains, discolorations, [or] crystallization” on the packaging.
