Human Factors; Procedure
The Skyhawk was westbound level at 10;000 FT and reported a near midair collision; the aircraft passed about twenty feet below him. I was not speaking with an experimental nor did I observe his target in time to call traffic to the experimental. After the Skyhawk called the NMAC; I did observe a target at his twelve o'clock and less than a mile. This target went on to clip Bigg's 'RED' airspace before calling my Relieving Controller for services. The Relieving Controller noted with 90% certainty that experimental was the offending aircraft. This occurred in the outer area; so the only thing that could be done is increasing my vigilance. The offending aircraft was reported as a jet; so maneuvering the Skyhawk out of his way; especially considering the lack of communication.
ELP Controller described a conflict event between an IFR aircraft and an unknown/unobserved VFR jet; allegedly the offending aircraft in this case.
