A source told Censor.NET.
The source says Marrone was the one to organize a report on Markiv to Italian authorities.
Maurizio Marrone is member of Piedmont regional parliament, member of Fratelli d'Italia political party (conservative nationalists), and coordinator of a fake "Donetsk People's Republic" office in Turin.
Marrone has visited militant-controlled areas of the Donbas two times.
As reported, Vitalii Markiv was detained in Italy on July 1 for allegedly killing Italian photographer Andrea Rocchelli in the Donbas in 2014.
Italian lawyer of Markiv calls upon everyone who was with him in the Donbas to testify in the case. He invites witnesses to come to Italy, but is as well ready to arrive and gather evidence in Ukraine.
