(ANSA) - Palermo, January 11 - The investigation into the murder of Vincenzo Greco, 36, is following a mafia-related line of inquiry, sources said Friday. The construction worker was riddled with bullets on Thursday when driving an off-road vehicle on a road connecting Belmonte Mezzagno to Santa Cristina Gela near Palermo. The victim does not have a criminal record and is the son-in-law of Filippo Casella, a man killed in 1994 when he was 32 years old in Belmonte Mezzagno.
