Emmet Granger
Emmet Granger runs a farm located south from the gang’s hideout. Reach that place and speak with the man.
You now have to help Emmet on his farm. Get into the pig pen. Pick up manure with the pitchfork and move it into the wheelbarrow. After collecting all the manure you have to take the Wheelbarrow to the place where manure is stored.
The next step is to blow the manure up. Use a dynamite – set it on fire and throw at the manure.
This incident makes Emmet Granger angry. He challenges Arthur to a duel. Press the right trigger only about halfway and shoot once the bar is full. Kill Emmet before he shoots first. You can hit any of his body parts.
Approach the gunslinger’s corpse. Take out the camera from your inventory – this item is in the same slot as binoculars. Take a picture of dead Emmet Granger.
Search Emmet’s corpse – you will find Granger’s Revolver, a unique weapon.
All the animals ran off while I was searching his cabin. There is a harmonica that you can give to Sadie later. I think I sold it not knowing it would be useful later.
