[Investigation scene, Fathers and Sons] (4)

From the viewing area, go right and down the ramp to basement level 1. Head down the hallway and interact with the note on the doorframe of a locked door. This is 'Note on the door' (Evidence 1/2).

Enter the morgue through a doorway and interact with the book on the desk. This reveals 'Crematorium shift schedule' (New Mind Palace clue) and 'Crematorium registry' (Key Evidence 1/6).

Interact with the key on the desk where the book was. This is 'Crematorium keys' (Key Evidence 2/6).

Return to the locked door and use the 'Crematorium keys' to open it. Descend to basement level 2 and interact with the green ooze. This is 'Stinky green slime' (Key Evidence 3/6).

Enter the main crematorium. Interact with the shovel in the slime and examine its handle and bloody back. This is 'Bent fireplace shovel' (Key Evidence 4/6).

Use a melee attack on the padlock to unlock the crematorium storage. Enter and interact with the rolled-up rug leaning against the far wall. This is 'Reeking rug' (Evidence 2/2).

Interact with the brush on the cadaver gurney at the back of the room. This is 'Stinky slimy cadaver gurney' (Key Evidence 5/6).

Leave crematorium storage and enter the Retrocognition vision.

Find the four critical scenes: near the fireplace shovel, near the cadaver gurney, near the stairs, and near the desk in the morgue.

Mark the scenes in chronological order: 1. near the desk in the morgue, 2. near the cadaver gurney, 3. near the fireplace shovel, 4. near the stairs.

After the vision, you will receive 'Brutus stunned the crematorium worker' (New Mind Palace clue) and 'An event in the crematorium' (Key Evidence 6/6). You will also receive 'Key Evidence Collected' and 'All Evidence Collected', along with +184 XP.

In the Mind Palace, combine the clues 'Crematorium shift schedule' and 'Brutus stunned the crematorium worker'. This leads to the deduction 'Locate James Warren'.

Leave the Oakmont crematorium.
