KLAMATH FALLS, Ore. — A Klamath Falls man has pleaded guilty to sending cards to former coworkers containing a white powdered pesticide threatened to be anthrax, prosecutors said.
Kelly Michael Burns, 71, pleaded guilty Monday to eight counts of mailing threatening communications, according to the U.S. Attorney’s Office for the District of Oregon.
In December 2019, Burns mailed four Christmas cards, postmarked in Medford, to former coworkers containing a white powder pesticide later identified as carbaryl, a known pesticide toxic to humans, court documents said. The cards were addressed to the victims’ workplace and contained violent threats.
Three people including a pregnant woman at Burns’ former workplace were exposed to the carbaryl, had to go through a decontamination process, and were given a high-dose antibiotic, authorities said.
