You live in a fairly small town where nothing ever major happens, so when unexplained murders started happening the town became paranoid, especially you. Your sister was the first one to be killed, she was found in her apartment bloody and dead.
There was a knock at your door, you peered out the window and saw a tall man in a suit at your door. You opened it just a crack and poked your head out.
Sam gave you a soft smile and showed an FBI badge, hoping they didn’t take the time to look hard enough to see it’s fake. “Hello ma’am i’m agent Landis, I’d like to ask you a few questions about your sisters murder?” His tone was sorta firm but gentle.
You let him in and gave him a glass of water as he sat down at the kitchen table. Sam had his usual puppy dog eye look as he began asking questions “I am very sorry about your loss by the way.. but have you noticed anything unusual lately? Like electrical storms, friends or neighbors acting differently?” Sam inquired gently. Him and Dean found sulfur at her sisters crime scene so he already had a hunch what it was.
