Deputy Duncan

Deputy Duncan is a character from The Sims 2 PSP. He first appears in Service Station but later (once the player buys Bella Goth's house) will offer the player's Sim a ride to Paradise Place if they got Mambo Loa's doughnuts for him. Since then, he will appear in the streets of Paradise Place. He will also give the player's Sim some money for getting started in their new home, and say that Paradise Place is haunted (allowing the graveyard game with zombies), and about the missing garbage man Gimi Branko (as well as say that picked up garbage can be sold to the shop owners). After that, his role in the game is not important anymore, but he can still be used for upgrading relationships, etc.

Trivia
His name is probably a reference to Dunkin' Donuts, since the national chain is the target of many jokes about police officers.
