Chapter 3 - The Brake Line
Derek Sloan did not run.
That made him look less guilty for about six hours.
Then his lawyer arrived.
The police interviewed him at Lakefront Fleet & Auto.
He was forty-one.
Certified automotive technician.
Twelve years at the company.
No criminal record.
No dramatic gambling debts.
No secret mafia tattoos.
He said he remembered Lucia’s Mercedes.
“Routine inspection.”
What did he do?
Oil.
tire pressure.
brake pad visual.
fluid.
road test.
Did he work near the left front brake hose?
“Yes.”
Why?
He said he inspected it because Lucia had complained about a soft pedal.
That complaint did not appear on the service order.
Who told him?
His supervisor, Aaron Cole.
Aaron denied.
Then Derek changed:
“Maybe I’m remembering another car.”
There.
Memory under pressure is not automatically lying.
But inconsistencies matter.
Then the invoice problem.
Lakefront Mobility Services and Lakefront Fleet & Auto were both owned by Douglas Mercer.
Mobility provided wheelchair vans and senior transportation to nonprofits.
Fleet serviced private cars and company vehicles.
The Moretti Foundation paid Mobility.
The Moretti estate paid Fleet.
Separate contracts.
Lucia had noticed Mobility invoices that duplicated route numbers.
An outside accounting firm now reviewed.
The first finding was not theft.
It was sloppy billing.
Three invoices had been resubmitted after insurance denials and then paid twice when accounts payable failed to match route identifiers.
Mobility had credited one duplicate months later.
Two had not been credited.
Total unresolved:
$14,260.
Not a fortune.
Still money.
Then another pattern.
Six rides billed to the foundation had never occurred.
Value:
$3,900.
Why?
Mobility said clerical error.
Driver logs showed the vans were actually used those days.
For what?
Private trips billed to a corporate account associated with Lakefront Fleet.
That was more serious.
The same owner shifting costs between entities.
Then the Moretti Foundation’s internal liaison to Lakefront was Salvatore’s office.
Did Salvatore approve invoices personally?
No.
An accounts payable manager did.
Salvatore’s role was oversight.
Lucia had asked him because the committee budget looked wrong.
Then Derek.
Why would an auto mechanic care about Mobility invoices?
At first, no reason.
Then police found he was Douglas Mercer’s brother-in-law.
There.
Family connection.
Not illegal.
Not disclosed to the Moretti estate because nobody had asked.
Then Derek’s personal bank records?
Police could not simply pull them because Luca wanted.
They sought legal process only after evidence supported.
What evidence?
A former Lakefront bookkeeper, Mia Carson, told detectives Derek sometimes picked up cash reimbursement envelopes from Mobility’s office.
For what?
“Parts.”
Did she see anything criminal?
No.
Did Derek have authority?
Sometimes.
Then one email recovered from Lakefront:
Derek - Mrs. M is asking questions. Douglas wants the Mercedes checked before Friday. Make sure nothing creates another complaint.
Ambiguous.
“Checked” could mean service.
Then a second message from Douglas Mercer to Derek:
She is taking it downtown Thursday. I do not need that car coming back with another problem attached to our name.
Also ambiguous.
Not:
cut the hose.
Then police obtained work-bay security footage.
Not from the Moretti garage.
From Lakefront shop three days before crash.
It showed Derek under Lucia’s car for eleven minutes longer than the billed inspection task required.
Could be normal.
The angle did not show his hands.
Then estate garage camera.
There was one camera over service entrance.
It captured Derek arriving the afternoon of crash in a Lakefront van.
Service log?
No scheduled appointment.
Carmen had let him through?
No.
A grounds supervisor named Tony Marks had.
Why?
Derek said he was following up on Lucia’s brake complaint.
Tony remembered.
“He said Mr. Mercer sent him.”
Did Derek sign visitor log?
Yes.
Reason:
brake check.
So Lucia’s memory of a gray-uniform man at the wheel was corroborated.
Not secretly.
He was admitted.
Then duration.
Twenty-three minutes.
Camera showed him leave carrying a small tool pouch.
No view of wheel area.
Then Detective Donnelly asked:
“Why was there no invoice?”
Derek said:
“Courtesy follow-up.”
Douglas Mercer said:
“I didn’t authorize it.”
Now someone was lying.
Then tool marks.
The forensic engineer could not examine original hose because it had been discarded.
But insurer photographs showed a straight incision.
Could a utility knife create it?
Yes.
Could another sharp edge during maintenance create?
Possible.
Could road debris?
Less likely given location and protected routing.
Then old replacement part record.
The brake hose had been replaced only fourteen months earlier.
That weakened the age-related failure theory substantially.
Why did original report say old hose?
Because Lakefront’s tow-yard technician listed:
“weathered flexible line.”
No one checked parts history.
The insurer accepted.
Then Salvatore’s tow-yard visit.
He admitted Derek showed him the hose.
Was the cut visible?
Salvatore said:
“Yes.”
Why then did Derek’s company later write age failure?
Derek told him after cleaning:
surface split only looked cut.
Salvatore believed.
Or wanted to.
Then Rachel asked Salvatore privately:
“Did you tell Derek Lucia was meeting an outside accountant?”
Salvatore hesitated.
“Yes.”
When?
Two days before crash.
Why tell an auto mechanic?
He did not.
He told Douglas Mercer.
There.
Salvatore had called Douglas because Lucia’s invoice concerns involved Lakefront.
He said:
“Lucia is taking these to an outside accountant Friday. I suggest you find explanations before then.”
That could be proper vendor notice.
It could also warn.
Rachel stared.
“Why would you warn the vendor before an independent review?”
Salvatore looked tired.
“I thought the duplicates were administrative.”
Then:
“And because Douglas has worked with us for fifteen years.”
Relationship.
Again.
Then the timeline.
Salvatore tells Douglas:
outside review Friday.
Douglas messages Derek:
Mrs. M asking questions.
check car.
doesn’t need another problem attached.
Derek visits estate without scheduled work.
Brake hose later fails with likely tool damage.
Suspicious.
Still no proof of intent.
Then police searched Lakefront premises under warrant after obtaining probable cause tied to record inconsistencies and suspected vehicle tampering.
Not because Moretti men demanded.
They seized:
service tablets.
tool logs.
billing records.
Derek’s work phone.
The deleted messages were the turning point.
Recovered from device backup:
Douglas:
Did you make sure she can’t take that car tomorrow?
Derek:
Yes.
Douglas:
Battery?
Derek:
Better.
Then no response for twelve minutes.
Then:
Derek:
She won’t get far if she ignores the warning light.
There.
Luca read a copy only after prosecutors permitted disclosure through counsel.
His hands shook.
Rachel said:
“Do not interpret beyond text.”
What did it prove?
Douglas wanted the car unavailable.
Derek did something he considered “better” than battery.
He expected a warning light.
Did he intend a crash?
Not necessarily.
Then Derek’s attorney approached prosecutors.
Cooperation discussion.
Derek gave a proffer.
He admitted cutting partly through the outer brake hose.
Why?
Douglas told him to make the car “unusable” because Lucia was threatening their contracts and wanted to drive downtown with invoice files.
Derek claimed he expected brake-fluid loss sensor or soft pedal would stop her before leaving estate.
Did the Mercedes have a specific warning system?
Low brake fluid could trigger warning, but not necessarily before pressure loss became dangerous.
He was a certified mechanic.
He should have known.
Then:
“Why not disconnect battery?”
Derek said:
“Too obvious.”
There.
The goal was to make the car appear unreliable.
Then:
“Did Douglas tell you to cause a crash?”
“No.”
“Did he tell you to cut brakes?”
“No.”
“Did you tell him you would?”
“No.”
Then why “better”?
Derek thought a breakdown away from home would convince Lucia to stop using the car and delay meeting.
Reckless beyond belief.
No need a murder plot.
Then why did he come to estate?
To deepen the incision he had begun during shop visit?
Yes.
There.
He had partially nicked the hose at Lakefront three days earlier.
Then worried it might not fail soon enough.
He returned and cut deeper.
Lucia saw him.
He lied:
checking noise.
Then she drove.
The hose held until pressure and movement completed rupture.
He said he panicked after crash.
At tow yard, he told Salvatore it looked cut before realizing that admission could expose him.
Then his company’s report changed to age failure.
Who changed?
Douglas.
Did Derek ask?
Yes.
Did Douglas know Derek had cut it by then?
Derek said:
he told him after crash.
Douglas denied.
Records and texts would decide.
Then charges.
Prosecutors charged Derek with felony offenses related to vehicle tampering and reckless conduct causing serious injury, along with evidence-related charges.
They did not charge attempted murder immediately.
Intent to kill was not established.
Douglas faced separate charges tied to obstruction, false records, and alleged direction to disable the vehicle, plus billing fraud review.
The final charging decisions were not Luca’s.
Good.
Then Salvatore.
No criminal charge for the sabotage.
But police documented:
he concealed passenger status.
he failed to disclose the apparent cut after visiting the tow yard.
he had warned the vendor about Lucia’s planned outside review.
Could he be charged for false statement?
His initial lie had been to family and later police? He first denied to police too.
Detectives referred.
Prosecutors evaluated.
His attorney negotiated a formal correction of statement while obstruction analysis continued.
No immediate arrest.
Then Lucia.
Denise interpreted the update.
Police asked whether she wanted full detail.
YES.
They explained:
Derek admitted damaging hose.
Douglas allegedly asked to disable vehicle, but evidence of his exact instruction remains disputed.
Salvatore is not accused of cutting brakes.
Lucia sat very still.
Then signed:
SALVATORE WARNED THEM.
Yes.
He had.
Then:
NOT SAME AS CUT.
There.
Even she separated.
Then she asked:
WHY DID HE LIE?
Nobody could answer except Salvatore.
Lucia requested meeting.
Rachel asked:
“Now?”
Lucia signed:
AFTER POLICE.
Good.
Then Luca.
He had spent forty-eight hours wanting Salvatore to be the saboteur because the story would have been clean.
Uncle lies.
uncle cuts brakes.
fiancée hides mother.
everyone adjacent is enemy.
Reality refused.
Derek cut the hose.
Douglas may have directed a disablement without specifying means.
Salvatore compromised an investigation by protecting a longtime vendor and family reputation.
Vanessa pushed an unauthorized care placement.
Different failures.
Different consequences.
Luca sat in his study and stared at the old instinct to make them one conspiracy.
Then Rachel said:
“You do not need one villain for the house to have failed her.”
That was the sentence he wrote down.
May you like
Not because he liked it.
Because he knew he would forget.
