Stuck on onderon

[Coderedfield]

I'm stuck in the iziz murder investigation, I helped the twi lek lady with her sabotage on the 3 captains, and talked to everyone at the bar and did everything. now I'm stuck, and theres no droid head. Where can I find some head?

You have not talked to everyone in the bar (or you missed the clue when it was given).

Go and talk to the Beast rider in one of the side rooms.

If you did not pick up on the clue then go and deal with the droid merchant outside in the square.
