Boba Fett took the bounty, tracked him down to his home warren, and took him back to Tatooine. There, he was executed by being thrown into a sarlacc. Before being cast into the sarlacc, he swore revenge on Fett. Since Fett was later swallowed by another sarlacc, and it had been born from a spore cast from the one which ate Fhilch, he could be said to have had his revenge after all. Not that it did him a lot of good.
