I too had this exact problem with the 360's version but I have maxed out the game and still havent been able to find him .
Took a contract from salt key and when it sent me to kill him I had a wanted level and a pirate hunter came. When I finished killing the hunter the target got away but I didnt fail and now its stuck...
