Marvin de Luca is the head of the American mafia and is one of the first crime bosses you need in Objective 2- Head of The Underworld.

To discover the mission you need to send your minions to plot in West Coast (territory of P.A.T.R.I.O.T). He may be discovered in other locations of United States, however that isn't reliable yet. It is best to use Technician (, is found as a permanent capture mission in China) minions as they are the best plotters you have at that stage of the game and they will be needed to capture Marvin anyway after he is found.

5 Technician minions are required to capture him, however it is best to use Guard minions to reduce mission attrition and Valet minions to reduce heat gained from sending a considerable party over to one agency's territory.
