Two Colorado men were recently apprehended outside a federal penitentiary in Louisiana before they could carry out a plan to deliver packages of tobacco and methamphetamine to inmates inside the prison.
The Greeley men, 18-year-old Jose Francisco Herrera Munox and 19-year-old Angel Gonzales Gutierrez, planned to launch the packages over a security fence with an air cannon.
That type of cannon uses compressed air. The device is more commonly used by sports teams to send T-shirts into the stands at home events.
