Narrative:

Departed a private airstrip with jumpers on board to conduct parachute jump operations. After passing two thousand feet I contacted the local controlling agency to request traffic advisories during the climb; jump; and descent of the operation. I made the standard two minute call to ATC and ATC began to give advisories to the surrounding area that parachute jumping was in effect in 2 minutes. Before releasing the jumpers ATC informed me of an aircraft 2 miles northwest of my position; headed southbound. Not overly concerned with the traffic advisory because the suspect primary target was headed away from the drop zone; I told ATC I copied and we were 30 seconds from the jump on our current heading (giving more info to ATC to see if opposite direction traffic would pose a threat to our flight path). ATC did not advise of a potential conflict and I knew the traffic was heading in the opposite direction. I gave the command for the jumpers to open the door; spot; and exit. Upon descent I saw an aircraft fly directly over the drop zone where the jumpers were. I called ATC up and asked if they were talking to the aircraft and they were not. I cancelled radar services and began trying to contact the suspect plane on the local CTAF frequencies of nearby airports (airports not in our immediate vicinity) to raise the pilot but with no luck. The aircraft apparently made a 90 turn in course and headed directly for the dz; causing jumpers to pass extremely close to it in free-fall.
