Detective Yul Stenson was in his house watching the football world cup match when, suddenly, a football came crashing through his window, breaking it. He got up and looked out the window just in time to see three neighborhood kids, who were brothers, run around a corner. Their names were Mark Benson, Steve Benson, Stark Benson. The next day Yul got a note on his door that read “? Benson broke your window.” Which of the three Benson brothers should Yul question about the incident?
