Narrative:

I was relieved from the navajo/santan position during a period of slow traffic. One of the aircraft I had on frequency was a B757 direct to bxk and climbing to the top of my airspace FL210. During my relief briefing; the relieving controller shipped the aircraft to ZAB center. Shortly after; the aircraft reported a near midair collision with an aircraft at FL115 squawking 1200. This is a known jump aircraft that commonly uses this area but does not normally ask for advisories. Neither me or the relieving controller saw the aircraft and traffic was not issued on our end. Recommendation; the relieving controller needs to scan his airspace better and I need to pay closer attention when doing an overlap.

Title: P50 Controller described a Conflict Alert event immediately after a position relief; the reporter indicating that 'jump aircraft' frequently operate in the subject area without communicating with P50.
