Mission
Neville suggests rigging a letter addressed to him and tells him of Postman currently conducting his rounds in Old Vice City and tells him that they should go through the van and find a letter addressed to Mark, and rigged it with explosives.

They find their Post Truck and while Neville distracts the Postman - Don opens a letter a dressed to Mark Lupisella and stashes a small explosive device in it before resealing it. They follow the Post Mule to Mark Lupisella's location in Mendez Bros Avenue and waits for him to receive the letter before detonating the explosive and killing Mark.
