We have no solid idea what caused this guy to act that way.
Maybe he had become an alcoholic or a doper, someone still looking for his place in society after high school. Back in high school, he was a star athlete.
“Back in high school, he was a star athlete.”
So was Al Bundy, but he accepted his status in life.
Did he tell the cops "I played high school football, I hold the catskill high record for 5 touchdowns in one game!"
A drunk Al Bundy wanna be?
