LR25 aircraft on descent into destination airport. Reporter approach controller states that LR25 flight crew reported the near midair collision, but then didn't want to file a report. Intruder F15 aircraft had transponder off and apparently made a run on reporter aircraft and reporter didn't have time to take evasive action.

Narrative:
F15 returning to gsb VFR, 8500 ft pass in close proximity to an EMS LR25. The lear was on an IFR clearance descending into ewn. At the time of occurrence the LR25 pilot said he wanted to report a near miss. Radar traffic was not given. It appears the F15's transponder was off or on standby. Then F15 called gsb approach and was idented. Phone calls revealed the F15 had the lear on his radar at 10 mi and in visual contact at 4-5 mi. The lear did not see the F15 until too late, broke out at 9000 ft, for evasive action and flew through the wake of the F15. The F15 came from lear's 10 O'clock position. Lear pilot said they missed by about 300 ft and felt F15 was playing with him. Lear pilot will not file near miss!
