A Mississippi veterinarian accused of using euthanasia drugs to poison a neighbor’s dog more than three years ago was found guilty in justice court this week.

Jackson news media reported that Copiah County veterinarian Stacy Gowan, of Brookhaven, was found guilty of poisoning the dog.

Because poisoning an animal is a felony, the case was sent to a grand jury by the Lincoln County Sheriff’s Office. The grand jury sent the case to justice court.

WLBT reports that a necrospsy was performed on the dead dog and found evidence of euthanasia drugs in his system. The owners of the dog said Gowan, who lived in the neighborhood, was responsible.

Gowan had reportedly admitted to baiting dog food with euthanasia drugs after she thought the dog had killed her chickens.

Board of Animal Medicine Executive Director Nancy Christiansen said the board would be looking into Gowan’s case now that a guilty verdict has been handed down.
