Store Dominik in the Locker is a mission objective in All in the Family in Deus Ex: Mankind Divided.
Walkthrough[edit]
With Dominik incapacitated, you need to sneak back out. Drag him out of the laundry room and head back to the stairs going up to the second floor. Use the stairs on the Western side since this will put you closer to an apartment you have cleared and has a lift just outside it.
Drag Dominik into the apartment you entered the complex from. Do yourself a favor and save (just in case). Dragon him to teh Western side of the apartment and to the open balcony door.
Go to the right-hand side of the balcony where there is no fencing. Carefully maneuver the unconscious Dominik over the ledge and drop down onto the lift with him.
Drag him off the lift and over to the nearby locker. If the unconscious man is not cooperating on the lift, just throw him off it. It is not likely to kill him. The locker is found through the Southern side of the area you leave the Dvali Safehouse in.
