Who is Kliner's son from Killing Floor and what is their importance?

At six feet two, and about one hundred and ninety pounds, the Kliner's son is no lightweight. About thirty-years-old, he has a restless energy and his father's position in the town make him bolder than he should be. A tough looking guy, he is broad shouldered and black haired with black hair on his arms. When he notices that Jack is interested in Roscoe, he takes it upon himself to try to straighten Jack out. He tells him that Roscoe is off limits and that she is his and that for five years, she has been waiting for him. He is also one of the four men sent to kill Jack at Hubble's, and is killed by Jack for his insolence.
