Unfortunately, Roz Kelly didn’t have the best of luck after her short stint on Happy Days. Rumor has it that she was plagued with mental health issues and in 1998 she was actually arrested for shooting in the direction of her neighbors home because their car alarm woke her up. Just two years later she was arrested and sentenced to four months in jail after she brutally attacked a man with a cane.
