Mercy noted that all the other teeth had perfectly straight roots.

“I’d hate to extract this tooth with those difficult root tips—I’d send her to a specialist if she’d needed it removed. But my point is that the roots are identical on both sets of films. The same tooth on the opposite side of her mouth does the same thing, and they match.”

“It’s not a common root formation?”

“It’s not uncommon. But these are identical.” She moved one of her films over the old one and Mercy saw that everything lined up perfectly. The crooked roots, the straight roots, and the shapes of the other teeth. “I had to retake the new film a few times to match the angle of the old one, but I caught it.”

“It’s Corrine,” Mercy stated.

“Yes.”

“That poor family.” The photos from the home flashed in her memory. Alison, Amy . . . gone.

“We didn’t find any remains of shoes, or belts, or wallets,” Mercy mused out loud. “Does that mean they were put in the culvert naked? Or were they already skeletal remains when they were hidden there?”

“Did you see the soil report that was just finished?”

“Not yet.” She made a mental note to check her email.

“I read it. The soil tests indicate that the bones have been there the whole time.”

“Interesting.” Mercy tried to imagine the work involved in dumping an entire unclothed family in the culvert. “I wonder if he put them in the other end first. Maybe the bodies are what caused part of the backing up of the culvert to start with.”

“And the bones were eventually washed out the other end?” suggested Dr. Harper.

“Yes. They were really embedded in the debris backing up the culvert, weren’t they?”

“They were.” One side of Dr. Harper’s lips curved up. “Could be ironic that the way he disposed of the bodies is what caused them to be eventually found.”

“And it’s reasonable that the remains could have skeletonized since last summer?”

“Absolutely.”

“How will we figure out if the last skull is the brother-in-law?” Mercy asked. The brother-in-law could be the murder suspect she was searching for. But did he kill the Jorgensens too? “I still don’t know his name. I can’t find any records of Corrine’s family, and Richard’s uncle was no help.”

“There’s always DNA testing, but it will take time. We can compare the unknown skull’s DNA to Corrine’s. If they’re siblings, they should have about fifty percent matching DNA.”

“I plan to get that test rolling as soon as possible,” Dr. Victoria Peres said as she entered the room. “Nice to see you, Agent Kilpatrick. I’m glad we had some good news for you.” She frowned. “I guess it’s not good news, but helpful news.”

“Definitely helpful,” agreed Mercy, noticing Dr. Peres carried a skull. “Now we’re down to two mystery skulls instead of four.”

“Actually we’re down to one mystery skull.” The usually calm and collected woman spoke in a voice that was higher than normal.

Mercy’s skin tingled. “What did you find?”

Dr. Peres held up the skull, and Mercy recognized the different shape of the eye sockets. “That’s the Asian skull,” said Mercy.

“Yes.” The forensic anthropologist flipped it over and indicated the opening on the bottom. “Can you see in here?” She shone a penlight inside the skull.

Mercy leaned closer, wondering what the doctor expected her to see. She couldn’t read every bump and fossa the way Dr. Peres could.

“It’s always bothered me that the color of the skull was slightly different from the other five,” Dr. Peres said. “And it felt more brittle to me. I was about to run dating tests on it when I spotted something inside. I blame myself for not getting it fully cleaned out right away. Stubborn dirt and the awkward location kept me from seeing it.”

Mercy searched the inside of the skull. Her gaze stopped on some small scratches. “Is that a year?” Mercy took the penlight from the doctor and moved closer to the opening. “It says 1969. But what do the letters spell?” She squinted. Someone had awkwardly carved the numbers and letters inside the skull.

“I think they’re someone’s initials.”

“Someone put the identity inside?” Her mind raced. It must be a birth year and the victim’s initials.

“No. I think this is a war trophy from Vietnam.”

Mercy drew back, horrified at the thought. “Seriously?”

“It’s my theory. I’ve heard of soldiers smuggling back skulls or bones or clothing from wars. All the wars.”

“That’s sick.”

“There’s a market for it.”

“That’s even sicker.”

“Let me see it,” requested Dr. Harper. She opened a case and took out a pair of glasses with loupes attached to the lenses. Mercy’s dentist wore the same type. “The initials are HRR. I assume they belong to whoever originally brought home the skull?”

“Who knows?” asked Dr. Peres. “It could have had multiple owners over the last fifty years.”

“But why place it in the culvert? And was it put there at the same time as the Hartlages?” questioned Mercy, thinking out loud.

“I suspect you won’t know the answer to that until you make an arrest,” Dr. Peres said solemnly.

It wasn’t the answer Mercy wanted to hear, but she knew the forensic anthropologist was correct.

My father had a love of all things military.

I didn’t understand his fascination with these items because of his hatred of his time in the war. He condemned our government, which sent men to war, but would make special trips to see war memorabilia for sale. Mother looked upset every time he came home with a new purchase, but she never said anything about the money he spent. I suspect she knew better. Even I knew Father was in charge of the money. Mother had to ask several times when she needed to buy us clothes for school.

He had quite a war collection by the time I was ten. The items were kept in a big wooden armoire with a lock. When he was drunk he’d set a chair in front of the armoire and lovingly handle each item. If he was in a good mood, he’d let us touch some items in his precious collection. He’d tell us which war the item was from and speculate on the type of man who’d used it. Sometimes he’d recite stories about his collectibles . . . the men who carried the guns, wore the clothes, earned the medals. I knew the stories weren’t true; some of these wars had happened before he was born. How could he know who’d used those things?

He’d let us try on the hats. There was a black metal helmet worn by Germans from a very old war, and a weathered tan hat with a brim and a dirty-looking metal pin with an eagle and a shield. He claimed this one was used by Americans. It smelled old . . . like dust and gasoline and oil. Both were too big on my head.

My favorite hat was the red beret. It was slightly crushed but would mold to my head better than the others. Its patch had a star and a gold wreath, but Father said it wasn’t American. It was from Vietnam. The manufacturer’s label was in a foreign language, so I suspected he told the truth. Another neat thing from Vietnam was the camouflage-covered helmet. Someone had written Born to Kill on it with a fat black marker and drawn peace signs.

He wouldn’t let us touch the weapons. He had about a dozen knives with battered scabbards, and the prize of this collection was a long bayonet. I don’t remember what war it was from. He had several handguns, but I thought they looked like the weapons used on cop shows on TV and they didn’t hold my interest. The one gun I did like was a French submachine gun. It was long, black, and deadly. It looked like someone had added parts to a regular gun. My father claimed it had been stolen in another war and then used by Vietnamese guerrillas. Most of his memorabilia was from the Vietnam War . . . including some collectibles that shocked me.

He rarely talked about his war. The keepsakes from his war were pushed to the back of the armoire, and he rarely brought them out. When I’d find the armoire unlocked, I’d look through them, wondering which belonged to him and which he’d bought. He called the camouflage from his war “chocolate chip.” I never knew if that was a joke or real. He had a medal in a box. I don’t believe he earned it, because it was on a red-white-and-green ribbon and imprinted with a foreign language, but I could read the year. 1991. I suspected the Operation Desert Storm patch was his.

All these items were his obsessions. I believe he cared more about them than about his kids. Or wife. Sometimes he would lock himself in the bedroom for days and drink. Mother would sleep on the couch and tell us to leave him alone. I could hear him rooting through the armoire, muttering or swearing to himself.

After one long binge, Mother pried open the bedroom door. She’d been listening and pacing outside the door for an hour, concern on her face. When it opened, I saw him motionless on the bed, wearing the chocolate chip camouflage. I stayed by the door and watched her creep close to bend her head to listen by his mouth. I saw his chest rise and she silently dashed back out of the room.

I swear I saw disappointment on her face.

“Where’s the boss?” Officer Ben Cooley asked Lucas.

“Last I heard, Truman was going to the lumberyard to talk to Nick Walker.” Lucas frowned at the clock on the wall. “That’s been hours ago, and I left a message when he missed an appointment this morning, but I haven’t heard from him. I’ll try his cell.” He immediately punched numbers on a phone.

Ben sighed. He hated to bug Truman, but his wife was hounding him to get next Saturday off. Samuel had offered to switch shifts with him, but all changes had to be okayed by Truman. Ben’s wife wanted to buy tickets for some play in Bend, and she needed to know today if Ben could get the evening off.

He wouldn’t mind missing the play. He always fell asleep.
