Officials say what was uncovered was not dynamite, but rather explosives that could have been cobbled together from fireworks. Investigators believe someone could have been trying to put those together with other materials that were found in the safe to make a bomb.
The intent is still unclear. There is no present threat to the public, according to police.
UPDATE: According to Roanoke Co. Police, maintenance staff found a safe around 2 p.m. Monday and moved it to a facility where they identified something suspicious about the item.
