Some wild speculation on this picture.https://www.deviantart.com/egsproductions/art/We-will-not-let-you-go-Ember-s-Ghost-Squad-660402212https://www.deviantart.com/comments/1/660402212/4435144729

From left to right: Rachel, Froggy, Andrew (Randy Stair), and McKenzie. The shot girl on the ground is likely based on one of the future real life victims of Randy's grocery store massacre. Randy named his shotguns Rachel and McKenzie after his characters.
From the look of this drawing I would presume Randy used the Rachel shotgun to do most of the killing as Rachel seems like a merciless character. Rachel has character attributes of the real life killer Eric Harris - who Randy was obsessed with. Proof of this connection is obvious to the trained eye as Rachel is clearly holding a very specific rifle in this drawing - a Hi-Point 9mm Carbide, the same model gun used by Eric Harris in the Columbine Massacre of 1999.
Randy also spared one of his victims in the shooting, I would bet he was holding the McKenzie shotgun when he did that as the character of McKenzie seems to be a more forgiving person. McKenzie is the only character depicted in this image not showing aggression, she is likely based on the real life killer Dylan Klebold - the companion and follower of Eric Harris who showed mercy to one of his victims and allowed him to escape during the Columbine Massacre.
The characters of Rachel and McKenzie were in Randy's imagination recruiters of humans who would kill them so that their dead souls would join them in the ghost squad afterlife world "EGS".Post too long. Click here to view the full text.
