OK, this guy has a place holder and walks a triangle in north qeynos newbie area NE sector.
Place holder is a Gnoll Pup. One of the points on the triangle is 1115,-854. The other 2 points are along the east wall. But he stands for some time at this location (best for doing turn in). If you are there and a gnoll pup is in that location, kill the gnoll. Jracol will pop soon. respawn is about 5 minutes.
I was doing the rogue errands quest and he stayed up for 3 game days while I was running back and forth doing turn ins. Once he despawned I killed the gnoll and Jracol was back in 5 minutes. It was day light hours when he respawned also.
Hope this helps.
