Narrative:

While cruising over chs VOR copilot (who was flying/navigating) intercepted wrong outbnd radial; i.e. 181 degree right vs 215 degree right (J79). I was not watching this evolution because I was pulling out approach charts for destination (mlb). ATC called us at 20 DME and turned us right to join J79 (215 degree right). Contributing factors: 1) captain not backing up copilot navigation. 2) working on fourth leg of 12 hour duty day (fatigue). Supplemental information from acn 140373: I would remind my fellow aviators to always see that checks and balance systems exist in the performance or routine duties, especially when becoming fatigued from that long day we all have from time to time.
