CHAPTER FIVE
The east wing of Roosevelt Elementary felt different from the kindergarten section where Sarah Morrison had died.
Here, the hallways were wider and the classrooms larger, designed for older students who needed more space for group projects and activities.
Motivational posters lined the walls between classroom doors.
A display case showcased student science fair projects from the previous semester.
Miles and Vic followed Detective Stoller down the main corridor toward a small auditorium that had been converted into an interview space.
The room was typically used for school assemblies and parent meetings.
Rows of blue plastic chairs faced a small stage where a podium normally stood.
This morning, the chairs had been rearranged into a semicircle around several folding tables.
“This wing is on a different ventilation system,” Stoller said, unzipping the face guard on his protective gear. “Feel free to strip down out of the gear. Principal Davis and some of the others are in the auditorium to your right.”
Both Miles and Vic started working their way out of their gear.
When they were out, Stoller collected them, draping them over his arm like discarded coats.
“You don’t need me for the next part. I’ll be back out front if you need anything.
” He gave a nod and headed out of a set of double doors at the end of the hallway.
To their right, the auditorium doors were partially opened.
When they stepped inside, Miles saw that the windows overlooked the playground and athletic fields behind the school.
Under normal circumstances, children would be running around the jungle gym and playing kickball.
Today, the empty playground equipment cast lonely shadows across the grass.
Principal Margaret Davis sat in the front row, her hands folded tightly in her lap. Her face carried the hollow expression of someone processing trauma. Every few seconds she would glance toward the kindergarten wing, as if she couldn't quite believe what had happened in her school.
Three staff members waited in the chairs beside her.
As Miles and Vic approached, they all ran through a quick and hasty round of introductions.
The gym teacher, Mr. Peters, shifted uncomfortably in his plastic chair.
He was a tall, athletic man in his forties who looked on the verge of openly crying.
Mrs. Warren, the first-grade teacher, nodded in agreement.
She was older than Peters, probably approaching retirement, with gray hair and the patient demeanor of someone who'd spent decades working with young children.
Mrs. Chen, the school librarian, was a petite woman with kind eyes behind wire-rimmed glasses.
Vic pulled out her notebook and positioned herself where she could observe all four interviewees.
Miles took the adjacent chair, setting his tape recorder on the folding table between them.
The formal interview setup felt strange in the cheerful auditorium, but it provided the privacy they needed to discuss sensitive details.
“Thank you all for waiting,” Vic began, her voice carrying the professional warmth she'd used during their San Francisco interviews.
“We know this has been a difficult morning.
We're trying to understand what happened to Sarah Morrison and whether anyone noticed unusual activity around the school recently.”
“Sarah was one of the best teachers we had,” Peters said quietly. “The kids loved her. The parents loved her. She never missed a faculty meeting and always volunteered for extra duties. And God… she was happy to do it all.”
“Sarah stayed late almost every night, preparing activities and decorating her classroom,” Mrs. Chen said. “She truly cared about making learning fun for her students.”
Miles listened intently as they spoke, building a picture of Sarah Morrison as someone without obvious enemies or controversies. The kind of dedicated educator who wouldn't normally attract the attention of someone planning an elaborate murder.
“Did she have any conflicts with parents or administration?” Vic asked. “Any complaints about her teaching methods or classroom management?”
“Never,” Principal Davis said, speaking for the first time since they'd begun the interview. Her voice was hoarse from crying and shock. “Sarah's parent conferences were always positive. Her student evaluations were excellent. She was exactly the kind of teacher every principal hopes to hire.”
“There was one small issue this semester,” Mrs. Warren said. “But nothing that would explain what happened to her. This is… this is just unheard of.”
Miles felt his attention sharpen. Even minor controversies might provide insight into the killer's selection criteria. “What kind of issue?”
“It was about art supplies,” Mrs. Chen said, glancing nervously at Principal Davis. “Sarah had been using a particular brand of finger paints and modeling clay that came under scrutiny from the district safety committee.”
“What kind of scrutiny?” Vic asked. Miles was glad she asked, because he had no idea things like clay and fingerpaint could be harmful in any way, unless directly ingested.
Mrs. Chen looked uncomfortable discussing the details, but continued. “The manufacturer issued a recall notice because trace amounts of hazardous chemicals had been detected in some batches. Nothing immediately dangerous, but enough to raise concerns about long-term exposure in classroom settings.”
Miles felt something click in his mind. The manifesto's obsession with chemical contamination and molecular corruption.
Sarah Morrison's alleged role in poisoning innocent children with synthetic materials.
The killer might have targeted her specifically because of these recalled art supplies.
It would be a strange reason, but it did seem to fit with an equally strange method of murder.
“How did the school handle the recall?” he asked.
Principal Davis answered, her voice barely above a whisper.
“The school board reviewed the situation and determined that the remaining supplies posed minimal risk if used for the remainder of this academic year. Sarah was given permission to continue using them until we could order replacements for next semester.”
“So, she was still using potentially hazardous art supplies in her classroom?” Vic's tone remained neutral, but Miles could hear the significance she was placing on this information.
“The risk was considered negligible,” Davis said defensively. “The recall was precautionary. No children had been harmed by exposure to these materials. We even sent letters out to the parents and only one parent seemed concerned.”
Miles nodded, but he was thinking about the killer's twisted logic.
Someone obsessed with chemical purity and molecular contamination would see Sarah's continued use of recalled art supplies as evidence of her role in poisoning children. The letter’s reference to synthetic materials and processed educational tools suddenly made more sense.
“Did anyone outside the school know about this situation?” Miles asked. “District officials, community members?”
“The school board meeting where we discussed it was public,” Davis said. “The minutes are available online. But it wasn't controversial enough to generate significant attention.”
Mrs. Warren added, “A few parents asked questions during pickup, but most were satisfied when we explained that the district had approved continued use of the supplies.”
Miles filed away mental notes about the art supply recall.
It provided the first concrete connection between Sarah Morrison's activities and the killer's stated motivations.
Someone monitoring the school board meetings or website could have identified her as a target based on her continued use of potentially hazardous materials.
“Did Sarah seem worried about anything recently?” Vic asked. “Any changes in her behavior or routine?”
“She was excited about the five senses unit she was planning,” Mrs. Chen said with a sad smile.
“She'd spent weeks gathering materials and preparing activities. She wanted to make sure every child had hands-on experiences with different textures and smells. She just went on and on about it in the break room.”
The irony was devastating. Sarah Morrison had died while preparing lessons about the five senses, killed by a gas that would have attacked her sense of smell and taste before shutting down her respiratory system.
Miles wondered if the killer had deliberately chosen fluorine because of its connection to sensory experience.
Had the killer somehow known about Sarah’s lesson plan?
“What about access to the building after hours?” Miles asked, shifting toward the practical aspects of the crime. “Who would have keys or security codes?”
“All full-time staff have building access,” Principal Davis said. “Custodial crew, obviously. Some volunteers and substitute teachers have limited access for specific events.”
“How many people total?”
Davis considered the question. “Maybe thirty people with regular after-hours access. Another dozen with occasional or limited access.”
“What about the ventilation system?” Vic asked. “Would someone need specialized knowledge to access the ductwork?”
Mr. Peters answered this time. “The HVAC system is pretty straightforward. Maintenance workers access it regularly for filter changes and seasonal adjustments. But we’ve not had work like that done here for at least… maybe four or five weeks.”
Miles thought about the delivery system Stoller had described. Timer-controlled release, pressurized container, remote activation. The kind of device that suggested engineering expertise combined with detailed knowledge of the school's ventilation layout.
“Has anyone requested information about the building's mechanical systems recently?” he asked. “Contractors, inspectors, anyone claiming to need access for maintenance or upgrades?”
The staff members looked at each other, but no one recalled unusual requests. If the killer had gained access through deception, they'd been subtle enough to avoid raising suspicions. All of their faces showed signs of horror and disbelief that this could even be a possibility.
“What about during school hours?” Vic asked. “Could someone have accessed the ductwork while classes were in session?”
“The kindergarten wing gets pretty quiet during lunch and recess,” Mrs. Warren said. “If someone knew the schedule, they might have had a window of opportunity. And… I mean, it’s just the ventilation ducts. It’s not like they’re under tight lock and key.”
The possibility that the killer had been inside the school during normal operating hours was chilling.
It suggested either inside knowledge or extraordinary boldness.
Someone comfortable enough with the building's routines to plant a sophisticated murder device while children and teachers were close by.
Miles looked around the small auditorium, considering what they'd learned.
Sarah Morrison had been a beloved teacher with no apparent enemies.
But she'd been targeted, possibly because of her continued use of recalled art supplies that fit the killer's obsession with chemical contamination.
The attack required detailed knowledge of the school's ventilation system and access that suggested either authorized entry or sophisticated breaking and entering skills.
“I think we have enough for now,” Vic said, closing her notebook. Miles watched her tuck it away into her small shoulder bag, wondering if she’d used it in San Francisco and he’d simply never noticed. “We may need to speak with some of you again as the investigation develops.”
Principal Davis stood up slowly, like someone who'd aged years in a single morning. “When can we reopen the school?”
“That depends on the final contamination clearance,” Vic said. “But the kindergarten wing will probably remain closed for several more days while we complete our investigation.”
The staff members filed out of the auditorium quietly, their footsteps echoing in the empty hallway.
Miles watched them go, thinking about how Sarah Morrison's death had shattered their sense of safety and normalcy.
A place dedicated to learning and growth had been turned into a crime scene by someone who believed kindergarten art supplies were instruments of molecular corruption.
When he thought of it on those terms, he suddenly understood why so many people thought his periodic table theory as nuts. It just sounded so bizarre.
“The art supply angle gives us something to work with,” Vic said once they were alone. “We can trace the recall notice, see who might have monitored the school board meetings, cross-reference with people who have knowledge of heating and air systems.”
Miles nodded, but his thoughts were already moving beyond this specific crime. “We need to expand the investigation,” he said. “If this person is following the periodic table sequence, fluorine won't be the last element they use.”
Vic gathered her materials and stood up. “Let's focus on solving this case first. Then we can worry about preventing the next one.”
But Miles knew they couldn't afford to think in such narrow terms. What if there was someone else out there, not this fluoride killer but someone altogether different, planning the next elemental murders?
Element ten, neon, for example, or perhaps they would skip ahead as Diana Hartwell had done with gold.
Either way, unless they could identify the coordinating force behind these attacks, another innocent person was going to die.
The art supply connection was their first real lead.
It explained why Sarah Morrison had been targeted and suggested that the killer was monitoring public information about chemical safety issues in schools.
Following that trail might lead them to other potential targets, or reveal the broader pattern connecting these elemental murders.
As they left the auditorium and walked back toward the kindergarten wing, Miles felt the familiar excitement of a case gaining momentum. But it was tempered by the knowledge that if this killer was indeed the same as the others, Sarah Morrison’s murder was not going to be an isolated event.
And whoever the next victim should be, time was running out for them.
