We exchange small smiles, and I’m glad I have him to help me keep things in perspective. I kneel beside him, study the print. It’s a partial, the front half of a shoe or boot. “Where did he pick up that blood?” I wonder aloud.

“Had to have stepped in it somewhere.” Glock glances my way. “I didn’t see any other prints.”

“Gotta be.” I rise, look around, heartened by the promise of evidence.

He shoots a final photo, gets to his feet and we look around. He walks slowly toward the small boy on the other side of the room and snaps a shot.

I go to the nearest body and kneel. It’s not easy looking at a dead teenaged boy. He’s lying facedown, his hands bound behind his back. His head is turned to the side and I see blood in his hair. Bits of brain matter and tiny white bone fragments from his shattered skull spatter the floor. His lips are parted. I see blood between his teeth. The small pink nub of a tongue that’s nearly been bitten off. Though I used the mentholated petroleum jelly, the reek of urine and feces repulses me.

Then I notice the binding at the boy’s wrists and my petty discomforts are forgotten. It’s some type of insulated wire. Speaker wire, I realize. Something an Amish man would never have in his home or anywhere else. The double knots are tied off neatly. The wire is tight enough to cut skin.

The fact that the killer used speaker wire niggles at me as I go to the kitchen. Who would have speaker wire on hand? Someone putting a sound system into their home? Their car or RV? Someone who works with audio or sound systems? Computers maybe? I’m working the possibilities over in my head when Glock calls out.

“I think I found where he picked up that blood.”

I walk to him and he motions down at the dead little boy. “There’s blood on that rug. I’d say the killer stepped on the rug and tracked it.”

He’s right. Disappointment presses into me. “I was hoping we’d find a better print.”

“Never that fuckin’ easy.” He snaps several shots of the blood-soaked rug.

I go to the kitchen and pull the sketch pad from my kit. Back in the living room, I begin a crude illustration of the scene, concentrating on the location and position of each body. I’m not a very good artist, but combined with the photos, this depiction will be a good record of how we found the scene.

I go to Amos Plank’s body. He, too, lies facedown with his head turned to one side. The pool of blood surrounding his head glitters beneath the work light. I kneel next to him. “Glock, did you get photos of the father?”
