What are the names of the persons who dump a body in a landfill?  Answer the above question based on the context below:  Joshua and his boss, Vincent, are driving to a hospital. Both have been shot and are in pain. Joshua thinks back to his childhood, when his father was shot in front of his eyes. In a flashback, Joshua and his partner, Mickey, visit people that owe money to Vincent.  They encounter a crazy druggie who tells them that a small-time drug dealer named Frankie Tahoe wants to kill Vincent. Joshua and Mickey inform Vincent, and the trio intimidate a guy who works for Tahoe into telling them where he can be found.  They find Tahoe at a nightclub. During a talk, Tahoe insults the religion of Joshua and Vincent, which they hold dear, and Vincent beats Tahoe to death with a baseball bat. The trio dump the body in a landfill. While doing this, Vincent reveals that Mickey and Vincent's wife have been having an affair. Vincent then kills Mickey. While Joshua and Vincent are having breakfast, Joshua tells his boss that he has become weary of the violence and wants to retire. Vincent admits that he has violent outbursts but insists that Joshua owes him his life. Angered, Vincent says that Joshua cannot retire.  He leaves to go home, where he discovers two men watching his house. While confronting them, Joshua appears. The men tell Vincent that they have been ordered to deliver him to Nino, a powerful crime boss. When Nino calls his men, Vincent answers the cellphone. Vincent and Joshua get in the car and are driven to Nino's house.
The answer to this question is:
Joshua
