American Dreams

 is a Stranger mission in Red Dead Redemption II. The quest becomes available during Chapter 2.

Story
A coldblooded murder is out on the loose in the world. During his adventures, Arthur Morgan can come across grisly crime scenes and collect maps from murdered victims chopped off heads. Collect three maps to combine the clue pieces to find the killer's location.

Walkthrough
The quest can be given by the Sheriff in Valentine, but stumbling across any of the three murder scenes should trigger the questline as well.

First Murder Location: Travel due south/southwest of Wallace Station and look for a grisly murder scene of a disembodied torso tied to a large bolder with the words "Do you see?" written on it. The victims can be found on a smaller rock nearby.

Second Murder Location: Travel east of Braithwaite Manor and look for a large tree. You can find a corpse nearby with it's severed head sitting not too far away.

Third Murder Location: Travel southeast of the Valentine and look for a wooden bridge, travel down underneath the bridge to see another torso hung off of the rafters. Nearby the words "Look at my works" can be seen. The head of the victim is found impaled on a wooden support beam nearby.

Once all three maps have been gathered, travel to Lucky's Cabin, southwest of Valentine. Search for a hatch outside and travel inside of the murderer's chamber. You can find a letter the murder wrote to his woman in the first room, and a knife can be interacted with in the second room. Afterward, the killer will sneak up from behind and knock out the player.

The player will come to with the killer in front of us. Knock him out and hogtie him and bring him to Valentine's Sheriff's Office. While bringing him into a cell, the killer named Edmund Lowry Jr., will attack the sheriff. Use Dead Eye Targeting to kill him. The Sheriff will give the player $20 in the reward.
