shooting at his house, the gun could have been lost by, taken from, or sold by the original killer. The same gun was often used in different crimes by different perps. But Decker believed it was the same shooter in both instances. And if that was the case, it let Leopold out. So Leopold was lying. Yet it was possible he had been told facts of the Decker case by the real killer. And if that were so, then Leopold was the best hope he had to find the person who had murdered his family. And all these others.
Despite the recent writing on the bedroom wall, the case was cold on the Decker family end. Conversely, it was red hot on the Mansfield High School end. So the Mansfield end was where he would focus—that and on Sebastian Leopold. If Leopold knew who the Decker killer was, then he knew who was behind the Mansfield crimes too.
He flashed his credentials at the perimeter security and walked through the front entrance. Yesterday had been disjointed and confusing for him in all respects. He didn’t know if he belonged in the middle of all this. He felt cut off from everyone and everything going on around him. But with the possible connection to the murders of his family, Decker knew that he did belong. He would be on this case for as long as it took. They would have to dynamite him out of here.
He didn’t head to the command center in the library. He went to the cafeteria and stared at the freezer. Then he looked at the ceiling tiles.
Cammie fiber, possible gun oil. Maybe all bullshit. Maybe.
He looked at the exit door. False lead too, or so he now believed.
He left the cafeteria, walked down the hall fronting the library, turned right onto the main corridor that bisected the first floor, and counted his steps off as he made his way to the rear of the school.
At each intersection with another hall he studied the lay of the land, first left, then right. Classrooms on both sides. The last corridor was where Debbie Watson had died. And where, to the left, so had Kramer the gym teacher over his breakfast sandwich and coffee. The rear entrance with the camera faced him. The angle of the camera still intrigued him. That had been deliberate. And deliberate action always had a deliberate motivation.
Then he looked at the classroom to the right of where Debbie had perished. ROOM 141 was stenciled on the glass.
He tried the door but it was locked. He pulled a pick set from his pocket and unlocked it. He stepped inside and turned on the light. He was surprised to see that it was set up as a shop class. They had had shop class back when Decker attended here. But he had thought it now a thing of the past. He looked around at the work places, table and miter saws, planers, drills, buckets of tools, vises clamped to wood, shelves on the walls holding metal tubing, nuts, bolts, wood, more power tools, extension cords, work lights, pretty much anything someone would need to build something. There were three doors at the back of this room. He opened two of them. Storage. He saw stacks of what looked to be old school projects: jumbles of half-finished furniture, metal twisted into various shapes, wire cages, part of a roof section, sawhorses, plywood sheets, stacks of wood, lots of dust, and lots of nothing.
The last door would not open. He took out his lock-pick set again and used it to open the door. He peered in. There was an old boiler in the far corner, now connected to nothing. Some window air-conditioning units were stacked on the floor against one wall up to about ten feet.
Again, a lot of nothing. He closed the door, walked back through the shop class, snapped off the light, and shut the door behind him. Down the hall from the shop class was Classroom 144, the one Debbie Watson had been coming from when she had been shot.
Decker looked over at the open locker on the wall. That was Debbie’s. She had been at her locker when she’d been murdered. Probably getting something to take with her to the nurse’s office. That might explain the detour here. Or it might not. Teenagers were unpredictable. They could be sick as dogs and stop at their locker to look for some gum. Or examine her face for zits in the mirror that hung on the inside of Debbie’s locker. He noted the tube of pimple cream standing up on her locker shelf next to a small opened pack of breath mints.
Blood splatters showed that she had been standing in front of her locker when she’d been shot. She had turned around to face her assailant, because she’d taken the blast from the shotgun directly to her face.
She had died at 8:42.
Decker had concluded that Watson was indeed the first victim. Which made him wonder what the shooter was doing between the whooshing sound at 7:28 on the front hall that Melissa Dalton had heard and Debbie losing her face on the rear hall one hour and fourteen minutes later.
Decker closed his eyes and thought this through.
It took me sixty-four steps and not even two minutes to go from front to back. The shooter appeared on the video at 8:41. But when did he leave the cafeteria? There is no way to be sure. And the biggest question of all: How did he go sight unseen from front to rear? I answer that, I answer everything. I don’t answer it, the case goes nowhere.
At least six-two, thick broad shoulders, over two hundred pounds. Decker had looked at the video footage of the shooter and did not dispute those physical estimates. Yet there was no male of that size and height at the school, other than the dead gym teacher and assistant principal, or a bunch of football-playing students hunkered in classrooms with a hundred alibis attached to them. And two of the players who were that size had been killed during the shootings.
It was as though the guy had appeared, done his killing, and then vanished into thin air. Since that was not a possibility, Decker had to be looking at this wrong somehow.
He went into Room 144 and sat down at the teacher’s desk. He surveyed the classroom. Twenty-one empty seats arranged in three rows front to back. One of them had been occupied by Debbie Watson. The last moments of her life were clear enough: an upset stomach; a trip to the nurse’s office authorized; a detour to her locker. And she was dead minutes later.
She’d been in the third row, fourth seat. He imagined her raising her hand, looking and feeling ill, getting permission to leave, walking out the door, never to walk in it again.
He rose and walked out the door, stopped, and turned. He was facing Debbie’s open locker. The mirror on the inside of the door reflected his image back. For some reason Decker didn’t recognize himself. This big fat bearded dude, drenched with rain, looking like hell.
But then he looked past the reflection and to something else in Debbie’s locker: a stack of textbooks and notebooks.
Decker looked back at Classroom 144 and then at the locker.
Life had coincidences. Serendipity abounded. Wrong place, wrong time. It came as the result of seven billion people jostling each other within the span of a single planet.
But there was an unwritten rule in police work: There are no coincidences. All you needed was more in-depth investigation to show that there are no coincidences.
He phoned Lancaster. She was in the library.
“Did you talk to Debbie Watson’s parents?”
“Yes.”
“Did they mention that she felt ill when she came to school?”
“No. I asked her that. The mom said she seemed fine. Might’ve been a bug that came on fast, though.”
“And what about the teacher? When Watson asked to leave?”
Decker could hear the woman flipping through her notebook.
“She said Debbie had looked fine but then raised her hand, said she felt nauseous, and asked to be excused.”
“Did she make out a note or—”
“They have them preprinted. The teacher filled in Debbie’s name and gave it to her.”
“So just thirty seconds from start to finish before Debbie left the room?”
“I guess about that.”
“What time did she actually leave the classroom?”
“The teacher thought maybe a few minutes before. Maybe five before the shot was heard.”
“That’s a big gap. Her locker is seconds away from her class. And I walked from the front of the sch
ool to the back in less than two minutes.”
“Maybe she lingered there for a few minutes. Maybe she thought she was going to throw up and was trying to collect herself. Look, why are—”
“I’ll explain later. It may be nothing.”
Decker clicked off and put his phone away. He was just about to have a very radical thought that might potentially crush certain people. He didn’t do this lightly. He did this only to get to the truth. The truth was worth everything to him. But he needed something concrete to go on before he could move forward on this.
Fate for Debbie was 8:42 outside this door. After that she would be no more, her life over. How would it run? Debbie raises her hand, gets permission to leave. She exits the class, but doesn’t go to the nurse directly. She heads to her locker and opens it. Another minute burned. But Lancaster had said the teacher thought it was several minutes, maybe as many as five. What had Debbie been doing all that time? Maybe she had been lingering or trying to steady herself, like Lancaster had said. But maybe there was something else.
