Owen sat on the curb with his hands cuffed in front of him.
When detectives separated him from Derek, his confidence collapsed.
He admitted that Derek had paid him to alter the gas system and install remote valves.
Derek had claimed he wanted to frighten Nora into leaving the house during their divorce.
Owen said he had believed the timer would trigger an alarm, not an ignition device.
The detectives did not believe all of his story, but they believed enough to keep asking questions.
By nightfall, forensic technicians had recovered the electronic igniter, the signal jammer, the screws sealing the rear door, and a remote-control application linked to Derek’s laptop.
The black phone contained months of messages between Derek and Owen.
There were also messages from Celeste Ward, Derek’s business partner.
Nora had expected them to prove an affair.
They revealed something worse.
Derek had told Celeste that Nora was dying from a neurological condition and that he would soon become Lily’s sole parent.
He had persuaded Celeste to help him move company funds into a private account because, he claimed, Nora’s medical expenses could destroy the business.
Celeste arrived at the police station that evening with an attorney and three years of financial records.
She admitted the affair, but insisted she knew nothing about a murder plot.
Her messages supported that claim.
Whenever she asked when Derek would file for divorce, he told her Nora was too fragile and might harm herself if confronted.
He had manipulated both women with different versions of the same lie.
The most damaging evidence came from a cloud backup Derek had forgotten to disable.
The hallway camera had recorded his conversation outside Lily’s bedroom the previous night.
His voice was unmistakable.
“Once I’m on the highway, start the gas,” he told Owen.
“The lock system will keep them inside.
Give it enough time to spread, then trigger the igniter.
The fire will erase the rest.”
Owen asked about Lily.
Derek paused for less than a second.
“She’ll be with her mother.”
That sentence ended every attempt Derek’s attorney made to describe the incident as a renovation accident.
Derek was charged with two counts of attempted murder, conspiracy, child endangerment, insurance fraud, unlawful surveillance, and evidence tampering.
Owen accepted a plea agreement after leading investigators to a storage unit containing spare components, cash payments, and printed diagrams of the house.
The life insurance policy became another piece of the plan.
Derek had submitted an electronic application using a copied version of Nora’s signature.
The beneficiary was not a trust for Lily.
It was Derek alone.
He had also taken out a second policy through his company.
Together, the policies were worth nearly three million dollars.
At the preliminary hearing, Derek entered the courtroom in a dark suit and looked toward Nora as though they were still husband and wife sharing a private disagreement.
His attorney argued that Owen had acted independently and that Nora had exaggerated ordinary marital conflict because she wanted leverage in a divorce.
Then the prosecutor played the hallway recording.
Derek’s face remained still until his own voice said, “The fire will erase the rest.”
His mother began to cry in the second row.
His older brother lowered his head.
Celeste stared at the floor.
Lily was not in the courtroom.
Nora had refused to let Derek’s defense turn her daughter’s terror into a public spectacle.
Instead, a child-interview specialist recorded Lily’s account in a quiet room with toys on the shelves.
She described the black phone, the whispered conversation, and the moment Derek said they would not be there when it was over.
Her account matched the electronic evidence in details no six-year-old could have invented.
Derek eventually rejected a plea offer.
He believed he could confuse a jury by attacking Nora’s mental health and portraying Owen as a rogue contractor.
During the trial, his attorney displayed therapy invoices, private messages, and notes from marital counseling.
Nora listened without lowering her eyes.
When she testified, she did not call Derek a monster.
She described objects.
