Deadly Premonition: The Director's Cut

Sidequest #11
Chapters Available: 8, 9, 12-16 and 18
Requirements: Need 1 bone fragment (Must have all 7 bone pieces if you want the reward)
Sidequest Giver/Location: Forrest Kaysen/various
Reward: .357 Magnum - Infinite ammo (only if you have all 7 bone pieces)
Unlocks: None

Speak to Forrest, Willie will run off with the bones but never fear he's just taken them to his dog house on wheels. Check the Dogmobile and you'll get your bones back, plus a Magnum if you had all the bone fragments. I would strongly advise you to get all 7 bones as the magnum comes in handy for later enemies.

NOTE: See the map for Bone locations, these are marked as Bone icons.
