PORTLAND, Maine (AP) -- A U.S. man accused of mailing cyanide to a British man who used it to kill himself has been indicted on new charges, including witness tampering and witness retaliation.
Sidney Kilmartin previously pleaded not guilty to federal charges of mailing injurious articles to Andrew Denton, of Hull, England.
The Portland Press Herald reports that the 53-year-old Kilmartin was indicted Wednesday on charges of mailing injurious articles resulting in death, mail and wire fraud, witness tampering and witness retaliation.
Kilmartin is accused of mailing the cyanide to keep Denton from telling investigators about Kilmartin's wire and mail fraud scheme. Kilmartin allegedly had advertised and mailed a substance he claimed was cyanide to several suicidal people. The substance was actually salt.
Kilmartin's attorney didn't immediately respond to a call seeking comment.
