With each mission in Crime Scene Cleaner’s new Nightmare mode, things get a little harder to spot. You have to check each location thoroughly to find new clues, but the later missions in the game will prove to be quite difficult. In the Trails by Blood mission, you need to locate 8 locker keys and 7 bodies to advance the mission. This guide will detail where to find them all in Crime Scene Cleaner.
Crime Scene Cleaner Trail by Blood Locker Card and Body Locations
When you load into the mission, your task is to clean up Miko’s Wellness Center and get rid of any evidence available. For that, you need to dispose of the 7 dead bodies within each room and also locate the 8 locker keycards. Let’s take a look at the location for each below.
Solarium

From the main entrance, head straight towards the Relaxation Zone and enter the Solarium beside the locker room, to your left. You will spot the first locker key, W024, hanging on the back wall, under the large moon.
Maintenance Room

Exit the Solarium and enter the Maintenance room just beside it to find the M014 locker key on the desk beside the computer.
Relaxation Room

Head back to the main area and stick to your right to find a pharaoh statue. It’s on the right if you come from the entrance. Investigate the mouth of the statue to find the M005 key hanging off it.

There is a second key to find within this area. Head into the bathroom with the sinks and pick up Locker Key W042 off the sink at the very back of the room. Also, pick up the first dead body in the middle and dispose of it.

After you exit the bathroom, look to your immediate right and pick up the M034 key from the wall lamp hidden behind the plant. Enter the Sauna beside it and pick up the second dead body.

On your left is an empty pool. Pick up the M017 locker key from the edge of the pool and the third dead body.
VIP Room

The very last room at the back is the VIP room. Take out the M025 locker key from the corpse sitting up on the couch on the left, and also dispose of the fourth body.
Men’s Locker Room

Make your way back to the entrance and enter the Men’s Locker Room. Open up the door to locker number M034 using the right key and pick up another locker key, W018. Also, find locker number M025 and use the key here to find the fifth dead body. Turn around and enter the shower area, unlock the door on the right to find the sixth body.
Women’s Locker Room
Right across the Men’s Locker Room is the locker room for women. Head inside to find locker number W018 and use the key here to get the Ruby music disk. Turn around and enter the shower on the right to find the seventh body.
How to Use the Locker Room Keys
Investigate both the men’s and women’s locker rooms and use the keys you have collected to clear out the lockers here. You will find evidence, unique items, and bodies to dispose of. Anything that isn’t worth your search gets thrown in the trash, and also clean up the blood within the locker to complete the mission objectives.
