006: Kiss Goodbye:
On the day of their murder, Agonni and his gang members had ordered lunch at their hideout, which was delivered by Uttar Mistry. After the food is delivered, Barbarossa Sassina drugged the wine with a soporific, causing Pearce Boyle and Angelo Fassi to fall unconscious. Because Agonni hadn't taken the soporific, Sassina was forced to break his neck before dousing him in petrol and setting his body alight.
