“Donna Stokes, the Realtor who was going to help Tanya find a new home to rent,” Eve said. “Donna has been missing since Wednesday. I think she walked in on Tanya being killed and it’s her blood in Caitlin’s room. That also explains why we found no blood or anything else in Coyle’s car. He used Donna’s car to take away Caitlin, the body parts, and other evidence from the house.”

The sheriff massaged his brow. “You’re not making any sense.”

“The evidence was all there from the start but we misread it.” Eve set her stack of photos on Moffett’s desk and hastily sorted through them until she found the one she wanted. She held up a crime scene photo of Caitlin’s room. “Take a look at this. The pillowcase is missing from Caitlin’s bed. The assumption was that Coyle took it. But why would he do that?”

“He was cleaning up evidence,” Duncan said.

“Of what?” Eve said. “The blood is on the floor and the walls. There is no blood spatter on the bed or the headboard . . . so there wasn’t any on the pillowcase. It’s gone because he used it to cover Caitlin’s head.”

“That’s a big leap,” Moffett said.

She pointed to the standing fan, tapping it with her finger. “We missed this fan. The power cord is cut off. That’s because he used the cord to bind her.”

Eve tossed the photo across the desk to Moffett and pulled another one from her stack, holding it up in front of each man in turn. It was a picture of the bloody print left on the floor by one of Caitlin’s shoes.

“This print from Caitlin’s shoe was found in the hallway near the garage. The bloody print is tainted with cleaner and motor oil, so we know it was made after the killings. We assumed her shoe fell out of one of the trash bags Coyle lugged out,” she said. “We were wrong. Caitlin put her foot down for a moment as she was being carried away. That’s proof of life.”

“Or it’s proof that a shoe fell out of a trash bag,” Lansing said.

Eve tossed the photo back on the desk, found another picture, and thrust it in Lansing’s face. “We also have this.”

It was a picture of a spec of blood on the wall. Lansing squinted at it. “Looks like just another spot of blood to me.”

“This one is different,” she said. “It’s undiluted and on the wall near the footprint. It’s Caitlin’s blood.”

“How do you know that?” Moffett said.

“Because Duncan saw Coyle naked and he didn’t have a cut on him,” Eve said.

“Not that I could see,” Duncan said.
