Portrayed by Carmen Argenziano

Mario Rivera is the boss of the murder victim Leonard Levitt.

Rivera tells Beckett and Castle that Len had changed the light bulbs in the underground passages in all of New York, but otherwise has no idea about what his employee could've done that led to his death.

Later, Ryan finds evidence that Rivera wanted to secretly sell the used bulbs to Costa Rica and was formerly a sniper in the military, giving him the skill to shoot Len from a long distance. Rivera finally admits the illegal sale, but his transaction was exactly the time of the murder of Lenny, and this place was under police surveillance, so he has an alibi.
