She shrugged. “We don’t have a motive yet for the break-in and murders. Rape could be it and her DNA could tie him physically to one of the victims if we don’t find their bodies.”

“At the very least, the swabbing process will humiliate him, which might yield some benefits,” he said. “You sure you don’t want to be there for it?”

“I’m positive,” she said. The swabbing procedure was performed by the jail nurse as part of typical rape kit protocol but the booking officer, meaning Eve or whoever she designated to take her place, would be present for the whole thing. Coyle would stand naked on a sheet of paper and be asked to brush and fluff his pubic hair. Anything that fell out would land on the sheet. If Coyle didn’t brush vigorously enough to get some pubic hair to fall on the sheet, the nurse would have to do it. The sheet, with whatever was on it, would be folded up and put in a sealed evidence bag.

After that, the nurse would swab Coyle’s penis, inner thighs, legs, arms, and torso with large Q-tips. The inside of his mouth would also be swabbed, primarily to obtain his DNA, but sometimes a victim’s DNA could be picked up if he licked or bit the victim. Blood and hair follicles would also be taken from Coyle. All of that would go into evidence bags, too.

“While you’re supervising the swabbing,” Eve said, “I’m going to do some more investigating.”

“Wise decision,” Duncan said. “Without the bodies, we’re going to need a lot more evidence to make those charges stick.”

At least she had some time to work. Arresting Coyle on a Saturday morning meant the judicial system would move a lot slower for him than it would if she’d arrested him on a weekday. The courts and other city, state, and county offices were either completely closed or barely staffed on the weekend. Coyle wouldn’t be arraigned until Monday. And, if he chose a public defender, he wouldn’t see a lawyer until then, either.

“Maybe the search parties in the park will find something,” Eve said.

“I wouldn’t count on it. Coyle could have dumped those body parts anywhere,” Duncan said. “I’ll go get started on the warrant.”
