Melting Point. Debra Cowan

there was anything accidental about it, so it appeared he would be working with the redhead until they closed these murder cases. Just dandy.

      The physical reaction he’d had to Russell during that dance had been warning enough, but combined with the insistent curiosity he felt about her, he had backed way off. And he intended to stay that way.

      “I have to hand it to y’all,” Kiley said from behind him. “The amount of patience this takes is incredible.”

      Collier shared a look with Terra. She’d had to remind him more than once that investigations took time and patience. He’d had to learn to curb his firefighter’s attack mentality and to carefully, thoroughly, follow the crime trail one step at a time.

      He’d wanted to work fire investigations for more than two years, which was why he had readily agreed to apprentice with Terra for no pay. Besides putting him in a good position to nab the promotion to fire investigator when another spot with her office opened up, he’d also taken on the additional and demanding hours as a way to forget about Gwen. And he had.

      Another fire investigator hadn’t been approved and budgeted until a few months ago. He’d taken the test, passed his independent assessment and been interviewed by Terra along with another candidate. She had offered the job to him, and the other man had found a job shortly thereafter with Oklahoma City’s fire marshal.

      Kiley trailed him through the center of the warehouse, wet grime sucking at her boots. “I remember Terra saying that arsonists typically set fires either for revenge, attention or to hide evidence of another crime. In this case it looks like the fires are being set as bait to attract the firefighters to the scene and kill them.”

      Collier turned to her. “I agree.”

      “I guess we should consider insurance fraud. If only to show we eliminated that motive.”

      “Warehouses are always prime marks for fire insurance fraud,” he admitted.

      “It’s possible that one person set the fire for insurance money and that another person murdered Lazano,” Terra offered, rubbing at her lower back again. “But this is too much like the other murders. I think our arsonist and sniper are the same person. And I think we’re dealing with an emotional fire setter as opposed to a pathological one.”

      “What’s the difference?” Kiley asked.

      “An emotional fire setter strikes out of revenge or hate,” Terra said. “A pathological torch gets off just by setting fires.”

      Kiley glanced around the warehouse. “Since we’re dealing with a serial killer who’s using the blaze to bait firefighters, we have an emotional fire setter.”

      “It appears that way.” Collier dragged a hand down his face. “So while arson definitely plays a role, we should be looking for someone who has more motive to kill than burn.”

      “I think you’re right.” His boss looked as grim as he felt.

      Kiley adjusted the too-large helmet on her head. “I’ll check on the warehouse’s insurance policy, anyway, just to cover our bases.”

      As they worked their way to the worst burn area, the fire’s origin, Collier documented every step with photos and sketches.

      On the east side of the interior, Terra halted in front of him and sniffed the air. “I don’t smell any accelerant. No gasoline, no kerosene, nothing.”

      Collier couldn’t smell any, either. Scenting accelerants was a natural ability Terra had that he didn’t, but she had said that didn’t matter. What would make him a good fire investigator wasn’t what he could smell, but what he observed.

      Scanning the coffee pallet and metal wall directly in front of him for the “low point” or point of origin, his gaze settled on a blackened circle on the concrete.

      Both women walked up beside him. Collier kept his focus on the spot in front of him, concentrating on determining if this fire was arson. Why would a fire start here? There was no heat source, so he could eliminate that the blaze had been accidental. He pointed to a small mound of charred material in the middle of the blackened circle. “This pile of rags is the point of origin. Looks like it may be towels.”

      “Let’s take a look at burn patterns on the pallets and coffee bags that burned, the leftover debris here and on the floor, ground, ceiling,” Terra said.

      After carefully bagging a fist-size amount of the remaining cloth, he used a small sterile paint can to hold a sample of the charred wooden pallet. Terra took photos of the places where the samples had come from, while Collier indicated the same on the drawing of the fire-sketch layout he’d started for the warehouse.

      To be thorough, he also sealed a handful of coffee beans, but he didn’t expect to find that they had absorbed any accelerant. He studied the charred pallet and a ten-inch stretch of black going up the metal wall beside it. He ran a quick test with the portable “sniffer,” a small boxlike instrument that detected carbons like those usually left behind in gasoline or flammable liquids.

      Glancing up at Terra, he was aware of Kiley in his peripheral vision. “The readout is negative for any kind of gas or flammable liquids. Right now it looks like the fire started with a match and a bundle of towels.”

      “I don’t think the arsonist tried to hide it, either,” his new boss said. “Probably lit this bunch of cloth then waited for the fire alarm to trip.”

      “They had probably already scoped out their position across the street.” Kiley glanced toward the front of the building. “And the fire was set close enough to the door for a quick exit.”

      “Another sign of arson.” Collier’s stomach tightened at the cold calculation indicated by the scenario they were starting to piece together. Calculation that could’ve killed him this time.

      Between that and the redhead behind him, his nerves were stretched taut. He shut the tackle box and rose. “From the obvious placement of the towels, I don’t think the arsonist cares if we figure out how the fire started. The hardest blazes to determine are the ones with a single match and a little thought.”

      “All the fires have basically been set in the same way and a rifle used in all four of them.” Terra braced a hand at the small of her back.

      “The first fire at the high school gym and this one tonight were started before the shootings,” Kiley observed. “But the fires at the motel and in the victim’s garage were set after the victims were killed. Just to get the firefighters to respond?”

      “I’d say yes.”

      “Lisa Embry and now Lazano give us two vics from the same station. Miller was with Station Three and Huffman with Four.”

      “Going through the first three victims’ shifts at their respective station houses gave us the calls they had in common.” Collier put a new roll of film into his camera. “We’ll check to see if Lazano’s work schedule coincides with theirs.”

      “All the murders have occurred within the first week of the month so we should cross-reference those dates with the rescue call dates.” Kiley flipped a page in her notebook. “We still haven’t found anything in the first victim’s background to suggest someone would want to kill him. As for the second victim, we haven’t found the blond woman witnesses say Rex Huffman was last seen with at that motel.”

      “What about Lisa Embry’s ex?” The third victim and her husband had gone through a nasty divorce and custody battle. He had ended up with the house and joint custody of the kids.

      Kiley’s jaw firmed. “We should talk to him again, ask him where he was tonight.”

      Terra picked up the thread. “Kiley and I will continue to work our way down the list of people who have died in fires within the last six months to a year. Or fatalities that occurred when any of these murdered firefighters were on the scene. The killer could be someone who blames the firefighters for the death of a loved one.”
