Murder of Elizabeth (Bipsy) Amirian and disappearance of Brian Shaffer

Elizabeth (Bipsy) Amirian was a singer and piano player living in California. Her dad was an abusive religious fanatic - but when she and her mom moved out she began to live a normal life.... until she met Mikey Wagstaff. He belonged to the ultra-conservative Seventh Day Adventist church and while he seemed kind, in the beginning, Bipsy quickly realized Mikey was more like her father than she initially realized. Then we cover the disappearance of Brian Shaffer. The last time he was seen, he was partying with his friends in a club. When his family reported him missing, the police tried to retrace his steps during his wild night out. Only issue? He never left the club.
