Liam Finney was an Irish man living in Ireland around 1947. He had some craftman skills as he repaired Collette Godsen's sheep pen.
He was present at The Thirsty Hog pub when Indiana Jones met Peter Paul Costello there and Finney warned Costello against talking with the archaeologist because it was too dangerous, but the crazy man ignored everyone.
As Costello was talking about the curse to the American, Godsen stormed into the pub and assaulted Finney, calling him lazy snake and slacker. She complaining that three lambs escaped her pen that night, and threatened him to solve the problem.
