But the ones who do it with high-powered firearms in the mouth or razors high up on the forearms, not on the wrists, are often filled with unrelieved rage at themselves. Female suicides are seldom if ever found in the last category.

Was Cesaire Darbonne’s information correct about his daughter? Did she not drink or smoke? Had she always been happy? What could cause someone that young and beautiful and full of promise to fire a bullet into the center of her forehead? Or had someone else been at the scene also?

THE NEXT DAY our coroner, Koko Hebert, lumbered into my office. Koko was one of the saddest-looking human beings I had ever known. His body was shaped like a soft-sided pyramid. His breath wheezed in his chest. He stank of nicotine and beer sweat, and sometimes trailed an odor that was worse, one that made me think of a mortuary in Vietnam after the power had failed.

Koko’s cynicism and anger were palpable. But his son had been killed in Iraq, and I had come to believe that his daily assault on the sensibilities of others was his own strange way of asking for help.

The grass was green and the sun was shining outside my window, but when Koko spread his buttocks on a chair in front of my desk, the sun might just as well have gone into eclipse. He took a huge drag off his cigarette, his brow furrowing as though his inhalation of cancer-causing chemicals were a moment of metaphysical importance.

“Would you not smoke in here?” I said.

He took a coffee cup off my desk and ground out his cigarette in it. “You want the post on the Darbonne girl or you want to tell me you don’t have bad habits?” he asked.

“I’m happy you came by.”

“Right. The lab call you yet?”

“Nope.”

“We swabbed both her hands. She was the shooter. It’s down as a suicide.”

“You’re sure?”

“You don’t have confidence in the atomic absorption test?”

“Let’s get something straight on this one, Koko. I appreciate the work you do. But I want the abrasive rhetoric out of my face.”

I could hear the hum of the air conditioner in the silence. “There is no false positive here. She had powder residue on both hands. She inverted the pistol and fired it straight into her forehead. It’s a suicide, plain and simple.”

“Her father said she didn’t drink or use. She was planning to start college. Why does a kid like that want to blow herself away? How did she end up in her own yard with a revolver her father never saw before?”

“Maybe I was looking at the wrong tox screen. The one that had Yvonne Darbonne’s name on it showed she was loaded on alcohol, weed, and Ecstasy. When I opened her up, I thought I’d put my hand in a punch bowl, burgundy and fruit, to be exact. She had also engaged in recent sexual intercourse, with multiple partners. In my opinion, there was not forced penetration, either. There was one bruise on the thigh, but considering the number of partners she had, that’s not unusual. I suspect she got stoned and loaded and was pumping it in four-four time.”

“What do you get out of it, Koko?”

“Out of what?”

“Offending people, testing them.”

He scratched the inside of his thigh, as though a mosquito bite were itching him beyond any level of tolerance. “If I go to meetings, can I learn how to use psychobabble like that?” he said.

I let out my breath and rubbed my temples. “What’s the rest?” I asked.

“There is no ‘rest.’ She was drunk and stoned and she balled a bunch of guys who didn’t bother to use rubbers,” he said. “You’re wondering why a kid like that would kill herself?”

RIGHT AFTER KOKO left the office, our forensic chemist, Mack Bertrand, called from the Acadiana Crime Lab. Mack was a decent, cheerful, pipe-smoking family man and one of the best crime scene investigators I had ever known. “We ran the weapon in the Darbonne shooting,” he said. “It was reported stolen out of a fraternity house at Ole Miss in 1999.”

“Any other prints besides the DOA’s?”

“It was oiled and cleaned recently. There were a couple of smears, but not enough to run through AFIS. Where you going with this, Dave?”

“Probably nowhere.”

“It’s a suicide, podna. Her thumb pulled the trigger. Her fingerprints were on the back of the frame. I think she turned the pistol around and squeezed off one right into her face.”

“What’d you get out of her cell phone?”

“Mostly numbers of kids at New Iberia High. Nothing unusual. Except…”

“Go ahead, Mack.”

“She made two calls during the week to the home of Bello Lujan.”

In my mind’s eye I saw a sun-browned man wearing white jodhpurs, with swirls of black hair on his arms. At least that was Bello ’s image today, although I had known him in an earlier and much different incarnation. “Why would she be calling a guy like that?” I said.

“He’s got a kid at UL. Maybe Bello ’s kid and the vic knew each other.” Then Mack paused. “Dave?”

“Yeah?”

“The girl took her life. Nothing will undo that. Bello wasn’t born. He was poured out of a colostomy bag. Leave him alone.”

“That’s strong for you, Mack.”

“Not when it comes to Bello Lujan,” he replied.

HAVE YOU EVER SEEN SOMEONE cause a disastrous accident by driving so slowly that others are forced to pass him on a hill or curve? Or perhaps a driver running a yellow light, trapping a turning vehicle in the intersection so that it is exposed to high-speed traffic on its flank? The person responsible for the accident rarely looks in his rearview mirror and is seldom brought to justice. I wondered if that would prove to be the case with Yvonne Darbonne.

I looked at my watch. It was 11:05 and I still hadn’t pursued the matter of the dye-marked bills in the possession of Dallas Klein’s daughter. I also had a hit-and-run homicide case on my desk, three cold cases involving disappearances from ten years back, and a gangbanger shooting that had left two dope dealers on Ann Street peppered with rounds from a.25 auto.

Welcome to small-town America in the spring of 2005.

Yvonne Darbonne’s diary lay on my desk. It had a sky-blue vinyl cover with a sprinkle of sunflowers emblazoned on one corner. The first entry was dated three months earlier. It read:

Went with him to City Park and threw bread to the ducks and fox squirrels. He put his windbreaker on my shoulders when it got cold. His cheeks were red as apples.

She had written on perhaps thirty pages of the book. She had used few names of people and no family names. The last entries seemed filled with happiness and romance and did not indicate any sense of emotional conflict that I could see. In fact, her handwriting and sentence structure and her general grasp of the world appeared to be those of a sensible and mature person. I looked at my watch and all the case files stacked on my desk and all the work sitting in my intake basket. Yvonne Darbonne’s death was going down as a suicide. My function was over, I told myself. I placed the diary in a desk drawer, closed the drawer, and drove to Lafayette to interview Trish Klein.
