Maine man who mailed cyanide to England to be sentenced

Sidney Kilmartin (Cumberland County Jail)

PORTLAND (WGME) -- A Windham man will learn his fate for sending a poisonous substance through the mail to a man who then died.

Sidney Kilmartin will be sentenced Tuesday morning.

Prosecutors portrayed Kilmartin as a calculated killer and argue he should get life in prison.

However, the defense says he suffered from mental illness and argued he should get anywhere from zero to 20 years in prison.

The 50-year-old was found guilty in 2016 of mailing injurious articles resulting in death and witness tampering.

He was scheduled to be sentenced last month but testimony in the case ran long, suspending his sentencing.

Kilmartin was charged with advertisement and mailing a substance he said was cyanide to several suicidal people.

It was really Epsom salt, but investigators say he later sent real cyanide to a man in England who used it to kill himself.

Kilmartin pleaded guilty to mail and wire fraud but denied charges of witness tampering and mailing injurious articles.

His sentencing is expected to resume at 10 a.m. in federal court in Portland.
