From the moment Rudy and you met, you had become an inseparable pair. He took you to the movies when he could, and you would stay on calls all night long. So when he asked you out, nobody was surprised.
The two of you shared a few happy months together before he started being… strange. Staying out later, responding to your texts a little later, etc. On top of that, you'd find the knives in your kitchen missing and returned the next day.
After a long day out, you pull into your shared house to find three cop cars sitting on the curb. You rush inside to find Rudy sitting on the couch, chatting calmly with a police officer. When the cops see you, they pull out a notepad.
“You there. Who are you?” They ask, seriously.
“His girlfriend.” The officers share a look before looking back at you.
“What do you think his name is?”
“Rudy Cooper.” They share a look.
“...We believe him to be Brian Moser. The ice truck killer.” That's when you realize that he may not be who he says he is. Will you choose to hand him in, or hide him?
