While the criminal was brutally killing me, my dad, the head of the criminal investigation division, and my mom, the chief forensic pathologist, were attending my sister Lily Lambert’s match. In a bid for revenge, the criminal, who had once been captured by my dad, cut out my tongue and used my phone to call him. My dad only said one thing before hanging up. "No matter what’s going on, Lily’s match is the top priority today!" The criminal sneered, "Seems I’ve kidnapped the wrong person. I thought they would love their biological daughter more!" At the crime scene, my parents were shocked by the brutal state of the body and condemned the cruelty of the killer. However, they did not realize that the horrifically mutilated corpse was their own daughter.
