Mills is angry. He's not letting this setback stop him.
He stomps back up to John Doe's apartment and forces his way in, even though Somerset insists they need a warrant first.
To make it official, they pay a homeless woman to give a statement to the cops, saying she called Detective Somerset "because this guy was looking creepy and s***."
John Doe's apartment is creepy, y'all. There's a big red neon cross on a wall above a bed, creepy crime scene photos, drawers full of pill bottles, and a room with about 17 (estimated) deadbolts on it.
He even has little cabinets memorializing each crime. Spaghetti sauce, Victor's hand. Ah, memories!
There's also a picture of a woman in a fur coat. We don't yet know her.
Somerset finds composition books filled with writing.
Suddenly, Mills yells out Somerset's name. In John Doe's makeshift darkroom, there's a picture of Mills. John Doe was the photographer.
