According to informant order came from same people who ordered deaths of Falcone and Borsellino.
Riina was recorded saying in 2013 that Di Matteo needs to be killed and blown up , like Falcone in the old days in Palermo. Shorty after that Riina received a letter that said: "Shut that damn mouth," letter was seized by prison authorities. In letter it also said "Remember that your family is free. We'll take care of the rest."
