Mike McCarthy, a.k.a the Tin Man, works as the Dorchester Crew's muscle man and got the nickname because when it comes to collecting, "he doesn't have a heart".
His reputation as a collector is so strong that he sometimes gets hired to do freelance collecting jobs for outside clients - but his heart and soul is always in Dorchester. Born at the local St. Margaret's Hospital, Tin Man considers Dorchester to be the best place on Earth. It's a community where everyone knows your name and if you ever have a problem, someone's always got your back.
Tin Man briefly left Dorchester to where he was, for a time, a student at MIT. Now he's back in Dorchester, working as a roofer and helping Steve run the Dorchester crew.
