The blast happened at the Escambia County Jail in Pensacola, but mystery surrounded what caused it.

It was first reported that the explosion was caused by a natural gas leak, but state investigators and federal authorities said they had found evidence revealing a crime was committed.

In the end, jurors noted that a spark from an unknown source ignited natural gas and caused the explosion.
