Who's the killer?

McCreery

As I crossed the portal worried about the boys I arrived at the other world, it was a pretty rainy day, so I ran to seek refuge in one place. I looked at a single-floor house and quite spacious, it looks like there were people so I started playing to be opened.

—Who are you and what do you want? —Opens the door, a tall man with a beard.

—Hi, I'm sorry for the inconvenience, but forget my cell phone at home and as you can see it's raining horrible, I just want to call someone to come by me, could you let me use your home phone? —McCreery asks kindly.

—Make it quick, my wife doesn't like visitors —the man replies as he lets McCreery through.

—Thank you very much, I won't be long —McCreery says as he moves inside the house.

—Who is it? —A lady who wears an apron asks.

—I grab him in the rain, he'll just make a call —the man replies as he watches McCreery talking on the phone.

—Ready, I'm sorry to bother you again, but could you use your bathroom? —McCreery asks.
