Ocala, Florida native Mark Barnett is accused of plotting explosions at Target stores up and down the East Coast. Investigators say his goal was to drive down the company's stock price so he could buy low and profit when the company rebounded.

The explosive devices were disguised as food and Barnett got close enough to pulling off the attack that he attempted to pay someone thousands of dollars to place the bombs in the stores. Barnett had hollowed out containers of stuffing mix, breakfast bars and pasta to place the explosives in.

The plot unraveled when his accomplice went to the police. An explosives expert has determined that the homemade devices, 1½-inch shells stuffed with explosive powder to be triggered by a battery, "were capable of causing property damage, serious injury, or death to nearby persons upon detonation.
