There were many suspicions that corrupt figures in authority had helped Leggio avoid justice, with plenty of suspicion falling on the General Attorney of Sicily, Pietro Scaglione; he was shot dead in 1971.
According to Mafia turncoat (pentito) Tommaso Buscetta the murder of Scaglione had three objectives: to remove a troublesome prosecutor, to bring heat on two rival Mafiosi who were being tried by Scaglione and who might be thought culpable, and to create the suspicion that Scaglione had collaborated with the Mafia.
