Anthony Casella was Peter's younger brother, not his son. He was present for the murder of Reds Caruso in the 1960s when Peter Casella was in prison for drugs. When Peter was shelved and banished to Florida in 1981 Anthony was also put on the shelf and became sort of a shut in. A plan to murder him was considered but never happened. Peter died in 1983 I think and Anthony died in the 1990s.
