The bodies of five men and one critically injured man, who later died, were found August 15 in two cars next to a pizzeria in Duisburg, western Germany. All of them, aged 16-39, had gunshot wounds to the head. Police found a total of 70 discarded gun cartridges at the scene. Eyewitnesses said their assassins had opened fire from two cars.
Police said the incident occurred following a blood feud between Mafia members from San Luca, in southern Italy.
The suspects have so far been charged with criminal activity, murder, and illegal arms supply.
