To late for Joey to answer but Amil was a well trained Marine sniper.
Most thought that Amil was directed to wack Joey by Lenny Strollo but Amil did it on his own in his failed hopes that Lenny would have him made.
That fact is also well known by the "I" but they figured that with Joey out of the way that it would be easy to convict Lenny for the hit.Strollo implicated Altshuler, his friend of more than twenty years, in the murder of rival gangster Ernie Biondillo Jr. and attempted murder of Mahoning County Prosecutor-Elect Paul Gains. Strollo also fingered Riddle and Turnage, black street thugs. In turn Lenny "The Rat" was allowed to live the good life in Canfield, Ohio and keep his millions :-(
