The fight started around 2:30 p.m. on July 29 after heroin, marijuana and tobacco fell from the sky and into the north recreation yard of Mansfield Correctional Institution, a prison spokeswoman told WJW.
An inmate picked up the package and hurled it over a dividing fence into the south recreation yard, starting the fight. After corrections officers cleared the yard, they went back to review surveillance footage and spotted the airborne drug smuggler.
After an extensive search of the prison grounds officers found the package, which contained 144 grams of tobacco, 65.4 grams of marijuana and 6.6 grams of heroin, hidden in an equipment room.
According to Corrections spokeswoman JoEllen Smith, drones have been used as modern-day drug mules in the U.S. prison system, but she said it's only happened a few times in Ohio.
It's not as easy as it might seem to transport drugs by drone, according to experts.
"They don't fly themselves," said Kyle Belman, who earns a living selling drones out of Columbus-based Cyclone Hobbies. "You'd have to be pretty savvy and know a lot about the scenario to pull something like that off."
