Murder Explanation:
During the house Scavenger Hunt, Arek’s list included an additional item, a photo album, located in the attic, as well as items in a particular order. After retrieving the few items, they needed to get, one of which being the first aid kit from his bedroom, he made his way to the attic to search for that photo album.
As the player scrounged around the attic, Arek accidentally triggered a lock on the attic door by tripping a tripwire with a box, locking them inside. Once the player was locked in, the killer heard the lock triggered, climbed up out of the secret staircase to the attic and punched the victim in the throat with a loaded glove, leaving a bruise behind.
While the victim was choking, I grabbed the EpiPens from the first aid kit my victim so graciously brought me and stabbed them all in the victim’s chest, killing them via a hotshot overdose of drugs. I took the empty syringes with me, along with a few other things to make their disappearance less noticeable, and left the loaded glove on the staircase, just to make this chase a bit more exciting. After all, EpiPens release adrenaline.
