David Sunfire is a figurant character, refered by Jim on Episode 1 of The Walkers(The Sims 2).
DECEASED. Gender: Male. Age: Unknown. Hair: Unknown. Relations: Jim; Lee; ??? Occupation: Possible Resident. / Survivor / ???
Nothing is known about this character before the Apocalypse.
It is believed that David already knew Jim before they rescued Lee, which created a strong relationship between the three of them.
He got infected by unknown reasons, maybe perhaps he was bitten by a lurker during a try to get supplies or just because the deceased had delayed manifestations.
Due to the character's death durring the early events of the breakdown, there is nothing to add on this matter.
