Consumed (Firefighters #1)(72)

As she closed in on the apartment in question, there was a walk-of-shame element to the aftermath, the excitement gone, the frenzy over, nothing but water and smoke damage left as artifacts of the emergency. These residuals were concentrated down at the end of the hall, and there was NBPD’s yellow caution tape running on a diagonal so that it cordoned off the scene’s door.

As she approached, she had her ID out, but the cop on the business side of the tape nodded and held the tape up so she could duck under.

“Gloves and booties are here,” he said.

“Thanks.”

Stepping over to a box of nitrile gloves and a larger container of shoe covers, she got herself ready. Don had assigned her a support role on the case, the primary investigator having already been over during the night as soon as the fire was extinguished. Residents and the firefighters had been interviewed then, and a preliminary report filed. She was on origin and cause, but, as a probie, also required to do a start-to-finish on the investigation as training.

As she pushed open the door with her gloved hand, voices, soft but insistent, murmured deeper inside the apartment.

Initializing her recorder, she spoke into her iPhone. “Upon entrance, there is extensive evidence of a high-temperature contents fire in the living area . . .”

Following investigative protocol, she continued to describe what she saw as she proceeded forward into a short hallway, stopping at the marker indicating where the first body was found. Continuing on, she noted the fire’s characteristics and prevalence, its spread from the kitchen, its—

Anne stopped as she looked through an open doorway and into a bedroom that had been spared. Of the burn, at least. The violence that had happened within the four walls more than made up for it, and the pair of crime scene investigators working by the bed didn’t look out of place in the slightest.

She’d read both the preliminary report and the log from the 499, and was prepared, but the bloodstained sheets was a pause-maker. All she could think of was Danny opening the door in the blaze and seeing a relatively smokeless room with a gutted seventy-nine-year-old woman tied by her extremities to the bed.

Must have stopped him in his tracks, too.

One of the uniformed crime scene investigators glanced up from where he was taking samples from the pillows. “Anne? How’re ya? Timmy Houlihan, Jack’s second cousin.”

“Oh, yes.” She lifted her gloved hand. “Hey.”

“Messy, huh,” he said as he indicated the stained bedsheets. “Horrible. This here’s Teresa La Favreau.”

Anne nodded at the woman who bagging something on the floor. “It’s been in the news.”

“Kid had a history. Went off his meds. Tragedy.”

“Awful. I guess the residents all warned her?”

“Yeah, well, it wasn’t just him. Some jewelry, engraved with her name and birth date, showed up late last night in the west end at a pawnshop. The guy who brought the stuff in smelled like lighter fluid and had soot all over him, and he took off before we could get there.” The man indicated around the tidy, modestly furnished environs. “We’ve got good prints and some hair samples, along with the images from the shop. We’re going to find whoever it is.”

Anne focused on the framed photographs of a young man that were on the bureau. “Well, I’ll just head down into the kitchen and do my part.”

“Good to see you.”

“You, too, Timmy.”

As Anne kept going, she talked into her phone, noting the evidence of intensifying heat in the hall, the Sheetrock eaten away, the studs in walls and the joists overhead showing signs of intense charring. Here, closer to the source, the fire had transitioned from contents to structure.

After taking samples and photographs, she began to construct a sequence of events. Photographs posted by the grandson on social media, since taken down and now used as evidence, detailed that he had been cooking his grandmother’s internal organs on the stove top. They hadn’t been selfies, however, which suggested they’d been taken by the second man. And then something had happened.

An argument? Or the plan all along?

According to the preliminary report, residents above the apartment and on the floor stated there had been a big explosion, and the fire had been fast and violent, something that required a secondary, sustainable ignition source.

Dousing someone in lighter fluid would not get that effect. On the other hand, tampering with a gas line? That would blow the apartment building up. In her training, she had read cases where entire houses were destroyed, with the debris scattered two hundred yards away in a circle.

No, that was too much power.

Instinct told her this was a gasoline blow. The problem was, with a fire as hot as this one had been? So much evidence was destroyed. But that would explain the explosion people had heard: Second suspect uses the lighter fluid to get the grandson on fire after they murder the grandmother and leaves. Grandson careens around the kitchen, trying to put himself out. Lights things like drapes, rugs, tablecloths, hand towels on fire. Heat begins to build. He transitions down the hall. Gasoline in enclosed can, stored somewhere in the kitchen when it shouldn’t have been, gets hot. Pressure builds and cannot be contained.

Gasoline in liquid form won’t catch fire below temperatures of 500 degrees. The vapors are the key. And if you have it in a storage container that ruptures from force, with sufficient air and ignition, you’re looking at a bomb because that vapor goes everywhere.
