All those child murders in Italy are really infamous. I remember most of all 3 of them:
1) Marcella Tassone (11 years old, sister of a 'ndranghetista), shot several times in the face, so the killers saw perfectly they were shooting a child.
2) Giuseppe Di Matteo, son of an informant, kidnapped by the mafia at the age of 12, held for 2 years, then strangled and dissolved in acid in 1996.
3) Giuseppe Letizia (13 years old, witness of a mafia murder), poisoned in the Corleone hospital by the mafioso doctor Michele Navarra in 1948.
