Leaving the tarp on the floor, I start toward the door, my heart pounding. Next to the door is a plastic fifty-gallon drum. The top has been sawed off and it’s being used as a trash bin. No liner. Using my flashlight, I peer inside. I see a crumpled bag of cat food, chunks of hog hooves, the broken handle of some garden tool. The sight of the bloody rags gives me pause. I lean closer, noticing a few red-black flecks on the side of the drum. I remind myself this is a butchering shed; the rags may have been used to clean or disinfect the equipment.

It’s not an unusual find, but I pull an evidence bag from my pocket anyway. Snapping it open, I use it to pick up the smallest rag I can find, stuff it inside. I’m in the process of sealing the bag when I spot another piece of fabric at the bottom of the barrel. The fine texture of the fabric tells me it’s not a rag. It’s dirty and torn and covered with chaff. I pull out a second bag—my last—and use it to pick up the scrap. It’s about six inches long and frayed. I level my beam on it and lean forward to blow away the chaff. The hairs at the nape of my neck prickle as I take in the bold white stitching against black silk. I recognize it immediately as a piece of the tank top Sadie Miller was wearing that day on the bridge.

Adrenaline rips across my midsection. I run my beam around the room, but there’s no one there. Nothing moves. Rain hammers against the roof; I can’t hear shit. Quickly, I tear the scrap into two pieces, drop half back into the barrel—evidence for the CSU—and stuff the other piece into the evidence bag. I push both bags into my back pocket and start toward the door.

Then I’m rushing down the corridor, anxious to get out. A right turn will take me back to the main door. I shine my beam left, spot yet another door at the end of the hall, next to what looks like a holding pen for the doomed hogs. I vacillate an instant, then take a left. Four strides and I reach the door. I reach for the knob, find it locked.

Cursing under my breath, I shine my beam into the holding pen. It’s constructed of steel pipe. I see a concrete water trough, which is dry. The dirt floor is covered with a mix of wood shavings and straw. No trace of manure. On the outside wall, a small half door is closed, and I suspect it leads to the outer hog pen.
