The suspicious letter that prompted a lockdown of the Executive Tower on May 4 was addressed to the governor and was threatening in nature, although the white powder inside was non toxic, according to Capitol Police.
Andrew Staubitz, commander of the Capitol Police, said he did not know what the powder was, but lab testing confirmed it was not hazardous or toxic. Staubitz said the threatening letter was addressed to Gov. Jan Brewer, but he refused to disclose what the letter said or whether it was related to S1070, the strict illegal immigration law signed by the governor in late April that led to waves of protesters at the Capitol.
“It was addressed to the governor, and it was threatening in nature, Staubitz said. “But beyond that we’re not going to comment on the content of the letter.”
The executive tower was locked down on the morning of May 4 after an employee of the governor’s constituent services office opened the letter and found the white powder. Capitol Police and the Phoenix Fire Department responded to scene, and the tower was reopened about an hour later.
The FBI is assisting in the investigation.
