The Murder Game: The Mask of Liars

One dead body.

Seven people.

And one murderer.

The seven people are locked inside a building together. In the middle of the room lay a dead body that they all know but do not remember. The occupants have to play a game to regain their memories while finding out who the murderer is.

Liam: The arrogant CEO
"I have too much paperwork to have the time to commit a murder. It wasn't me."

Taylor: The teenage outcast
"People always say it is the quiet one, but I am too much of a loner to interact with anyone. It wasn't me."

Lilian: The art teacher
"I would never hurt anyone or anything! It wasn't me."

Catherine: The jock
"I am all about sports; why would I ruin my full-ride scholarship with murder? It wasn't me."

Kevin: The nerd
"I barely go out and only care about learning. It wasn't me."

Elrick: The computer programmer
"I am always surrounded by my friends when I am not at work. It wasn't me."

Alan: The little boy
"I am a child. I-It wasn't me."

Who is the killer?
