Portland man indicted for sending threatening letters to Congress, officials
Investigation turned up about 100 envelopes sent with threats and powder
A 39-year-old Portland man was indicted Friday in connection with nearly 100 threatening letters sent to federal officials across the nation.
A federal grand jury indicted Christopher Lee Carlson with one count of mailing a letter with a threatening communication and one count of mailing a letter threatening to use a biological weapon against a U.S. Senator.
A federal investigation determined that Carlson mailed about 100 envelopes containing white powder and threatening letters to members of the U.S. Congress and certain members of the news media. The letters were postmarked in Portland.
One of the letters was sent to House Speaker John Boehner of Ohio. Another that contained what was thought to be a lethal white powder was sent to Sen. Barbara Mikulski of Baltimore.
Carlson is in custody and will be arraigned in federal court on Monday.
During the past few weeks, the FBI, U.S. Postal Inspection Service and the U.S. Capitol Police have recovered more than 100 threatening letters sent to U.S. senators and representatives. All letters have tested negative for toxic substances.
