In 1950, after being prison for 8 long years it was announced Luchiano Sindacco was returning to Liberty.
The acting Capo, Joseph Rosenberg, got word of this and realising that Don Sindacco would certainly have him killed for the mess he had made, fled to Vice City without telling a soul.
At this point Antonio, Marco and Alphonse had a problem. They knew the old man would come at them with everything he had to reclaim his power. This could not happen. Although they were all in this together Antonio Leone was their "Don" he was the eldest and wisest. But Marco and Vercetti felt they had come to a dead end - to grow they would have to do it on their own. Marco and Vercetti asked to leave and form their own family. Antonio accepted. Tensions were at an all time high and with their disagreements of the selling of narcotics. This was for the best. Besides, with Sindacco returning it would be much harder for him to fight back if he was against 2 families rather than 1.
And so in February 1950 Marco Forelli and Alphonse Vercetti formed their own family. It was around this time that Antonio's wife gave birth to their first child. He was named Salvatore Leone.
The Vercetti & Marco's gang growing in numbers and strength each week, one week in June 1950 however the Forelli family gained a very special member. His wife Marina gave birth to healthy boy who they called Santino Forelli, or "Sonny"
Upon his return Luchiano Sindacco indeed has his incompetent under bosses and lieutenants killed and their bodies dumped in a scrap yard in west Portland as a lesson. He was back, he saw theses young upstarts taking over his business and immediate action had to be taken.
Within days of his return, Luchiano had an Irish gangster, O'Bannon, who was on his payroll to contact Antonio, Marco and Alphonse with an offer to buy a very large consignment of drugs he has hijacked from one of Sindacco's men. Antonio declined – He was totally against drugs, but also found it suspicious that an old fashioned gangster like Sindacco was now dealing in narcotics. Marco and Vercetti jumped at the offer and agree to meet with O'Bannon in a disused warehouse in Staunton Island.
At an appointed time, Vercetti took 4 of his men and 2 of Forelli's men to the warehouse and waited for O'Bannon. Outside several of Sindacco's men dressed as policemen rushed inside the warehouse. Marco would have been there if he had not overslept. He was just about to arrive at the scene with 2 of his lieutenants, when he saw what he took for policemen going inside the warehouse. Assuming it was a police raid the three of them slipped into a coffee shop to wait until it was over. When they heard gunshots they fled to safety.
A few moments a witness saw 2 men coming out, hands in the air, with 2 policemen behind them. The quartet was actually Sindacco's men and they got into a Glendale and drove off. The woman ran over to the warehouse and saw the carnage – 8 blood smeared men sprawled on the floor, among them the lifeless body of Alphonse Vercetti still clutching his trusty Tommy gun.
