A federal jury has convicted a woman of mailing a letter that contained powder to the home of Republican Sen. Susan Collins of Maine.
Suzanne Muscara, of Burlington, was convicted Monday of mailing a threatening communication. She'll be sentenced later.
Prosecutors said the letter, which was intercepted, contained white powder, a reference to anthrax and a stick figure with the letter "X" for eyes.
The episode happened two days after Collins' husband opened a letter that claimed to contain ricin on Oct. 15, 2018. U.S. Postal Inspection Service screeners began inspecting Collins' letters and intercepted Muscara's letter before it reached Collins' home in Bangor.
Muscara, who was identified by a fingerprint, denied that the letter constituted a threat. She told investigators she didn't think it would be taken seriously.
