A Maine man has pleaded not guilty to mailing cyanide to an Englishman who committed suicide.
Investigators said Sidney Kilmartin, of Windham, Maine, advertised and mailed a substance he claimed was cyanide to several suicidal people. The substance was actually Epsom salt.
But authorities said Kilmartin mailed the real thing to Andrew Denton, of Hull, England, to keep him from telling investigators about his moneymaking scheme. Denton used the cyanide to take his life.
Kilmartin pleaded not guilty on Tuesday to mailing injurious articles resulting in death, wire fraud, mail fraud, witness tampering and witness retaliation.
