Steve Parsons, 48, of Stanberry, Mo., collapsed into a seizure soon after a Nodaway County jury convicted him of statutory sodomy and but found him innocent of forcible sodomy, the St. Joseph Press-News reported.
Nodaway County Sheriff Darren White said Parsons bought 100 grams of cyanide, the minimum order required by the Virginia company from which he ordered the pills, shipped the order overnight to his business, Parsons Tire & Battery in Maryville, and somehow ingested it in the courtroom.
"The preliminary autopsy reports, they confirm that it was, as the medical examiner put it, 'a classic case of cyanide poisoning,'" he said.
The final autopsy report should be completed later this week, the News-Press reported Monday.
White said Parsons took a drink from a cup he was allowed to bring into the courtroom, KCTV-TV, Kansas City, reported.
Parsons was charged July 20, 2012, in a Gentry County court with second-degree statutory sodomy and forcible sodomy for allegedly engaging in sex with a 17-year-old girl. A change of venue moved the case to Nodaway County, where he was convicted Thursday of the statutory sodomy charge
