Winchester or Angel?

1. Knock Knock

I heard a knock at the door. It was 2 pm, and I was home alone, but it's not my usual home alone day. This time I was sad. My housemate - My best friend - was murdered yesterday.

I set my mug of hot cocoa on the coffee table in front of me before rising to answer the door. I cautiously approached the door, ensuring the chain is in place, and put my hand on the handle. After peeking out the peephole, and seeing the two men in suits - one was wearing his normally, the other in a tan trench coat, his tie was loosened - I opened the door slowly...

I asked for ID, and they promptly provided. The first one held his up, showing a homicide detective badge with the name 'John Bonham'. The second man, the one in the trench coat, displayed his upside down. After 'Bonham' corrected trench coat's mistake, I could see the clearly marked name 'Stephen Stills'.

The first one introduced himself and his partner, "Hello Alexandra, I'm Detective Bonham, this is my partner Detective Stills. We're from Homicide Investigation, and we're here to ask you a few questions about what happened with your housemate, Erin."

I shut the door hard, probably causing the detectives to think I didn't want to talk. They had already started the path back toward their car when they heard the chain slide, the door opening soon after. When they re-approached the door, I invited them in with a hesitant gesture, asking them to use the door mat before coming inside.

I guided them to my living room, asked them to sit, and both detectives sat carefully next to but not too close to each other. The first detective - Bonham - began to ask me a series of questions. "Have you noticed any lights flickering lately? Cold spots, scratching sounds, rotten egg smell, or anything else out of the ordinary?"

Surprised at his unexpected choice of words, also confused, I responded, "Um, I don't know. I mean, I don't think so. Erin was a little paranoid before the...well, I thought it was paranoia. Wait, what does this have to do with the animal attack?"

"Ma'am, we're just tryna' be thorough. Could you think back - remember anything, anything at all - out of the ordinary in the days before Erin's death?"

"She did seem a bit paranoid...then there was..." I trailed off, mentally recalling the time she called me at work, frantic about some dog that was growling at her in the yard. "It's nothing."

"Every detail helps, Miss Alexandra" Detective Bonham urged gently.

"Oh, okay, but it's just Alex." I took a deep breath before continuing. "S-she called me yesterday morning, insisting there was a scratching at the door and that what sounded like rabid dogs growling whenever she even attempted to look out the window. She babbled on about someone coming for her because her 'time was up'. I called Animal Control from work to have them catch whatever dogs she was talking about, but they called back and told me there weren't any. I called her again to check if they were still there, and she told me they were, in fact there were more, and they were even angrier than before.  Frantic, I told her I'd be home soon, hung up, a-a-and-and-" I cut off, choking back a sob. "When I got home, she - she was..."

"Dead?" Detective Stills filled bluntly. That sent me bawling, just hearing what happened put into a word so finished.  Done.  No going back.

"Ca - Stills!" Bonham chastised before switching to a lighter tone, "I'm deeply sorry miss Alexandra, my partner can be a little...candid. I'm sorry to ask, at the risk of sounding insensitive," He looked at Stills as he said the last word. "But I feel I must. Were there any other strange events? Was your roommate having nightmares recently? Did she win or receive any kind of large fortune or a major event sometime in the last, oh, ten years?"

"I don't know." Confused, I made a face and tried to remember who these detectives reminded me of. "You sound like someone I know."  I continued to think hard, attempting to recall who it was that I were almost reminded of. It was on the tip of my tongue, I swear. 
Bonham continued.  "I'll take that as a compliment. I must insist you try to remember any major event that happened in the last ten years."

"What does the last decade have to do with my friend's murder?" These so called 'agents' were starting to sound a little...off. They're asking those weird questions like the Winchesters that Erin always babbled on about. "May I see your badges again?"

"We suspect your friend Erin may have been involved with another case we're investigating nearby." Bonham pulled his badge holder wallet out of his inner jacket pocket, flashing it to me quickly before putting it back.

I nodded over at Stills, gesturing for him to show me his ID. He pulled his out and showed it to me, but not as quick as Bonham did, allowing opportunity for me to snatch it and take a closer look. The first number on the badge was a two, causing me to panic. A detective badge number should always start with a one.
I attempted to maintain my composure as I handed the badge back to Stills, if that was even his real name. It probably wasn't.

A realization hit me.  How did I not notice before...the names on their badges are those of Led Zeppelin's drummer, and some other musician.
I need to get them out of my house.
