The documents hadn't all burned in the storage-building fire.
Several had been scanned into an administrative archive before the fire occurred.
Others were retained by banks, suppliers, and the accounting service that processed the garage's older statements.
When investigators compared those records with the copies used to accuse the son, they identified material differences.
Some approval details had been changed.
Certain invoices were unsupported.
And several payments led to entities connected to the partner's family rather than legitimate charity expenses.
The findings were referred to the appropriate authorities.
Meanwhile, the investigation into the motorcycle crash identified a dark commercial van seen near the industrial service road.
The van belonged to a salvage company controlled by the business partner's cousin.
A nearby commercial camera showed the vehicle entering the road shortly before the young mechanic's motorcycle appeared.
The footage wasn't perfect.
It didn't capture every second of the incident.
But it showed the van moving into the motorcycle's path immediately before the rider swerved.
Investigators obtained additional records and interviewed the driver.
His explanation changed more than once.
At first, he claimed he hadn't seen the motorcycle.
Then he said he'd stopped to ask the rider about a business matter.
Later, evidence established that he'd been communicating with the garage's partner shortly before the encounter.
The police examined whether the van driver's actions had been deliberate and whether anyone had arranged the meeting to intimidate or prevent the young mechanic from presenting evidence.
The old mechanic received updates through the proper channels.
He was furious.
Part of him wanted to drive to the salvage yard and confront everyone involved.
Then he remembered his son's injured face.
The little girl.
And the eleven years already lost because he'd reacted before understanding the facts.
So he stayed out of the investigation.
He provided records.
Answered questions.
And allowed the detectives to do their work.
That restraint wasn't easy.
But it was necessary.
The business partner stopped appearing at Iron Hollow after receiving notice that an independent financial review was underway.
He sent messages claiming the old mechanic had betrayed him.
He said the investigation would destroy the garage.
And he accused the son of returning to manipulate his father.
The old mechanic read the messages.
Then preserved them.
He didn't respond emotionally.
His attorney advised him to communicate through appropriate channels while the business and financial issues were reviewed.
The younger mechanics continued working.
Customers still needed repairs.
