Chapter 9: Every Thread at Once
The formal case opening changed the speed of everything.
Webb had the investigation designated as a Priority Public Corruption matter by end of day Thursday.
That designation unlocked resources — additional agents, subpoena authority, a direct line to the U.S.
Attorney's office — that had not been available when I was working it quietly from a desk.
By Friday morning, Callahan had a subpoena for Lyle Strategic Group's financial records for the past five years.
The prepaid phone had been traced to a convenience store in Cobb County.
The store had cameras.
The footage was being pulled.
Mercer had been placed on administrative suspension pending an internal Fulton County review and a parallel federal civil rights investigation.
His union attorney had called Webb's office twice on Thursday to discuss cooperation parameters.
Webb had been courteous and said nothing.
Cross was cooperating fully.
His recorded statement was forty-seven minutes long and covered not only the stop but three prior incidents he had witnessed involving Mercer — two of which had never been formally reported.
IA Liaison Huang sat in on the full recording.
When it ended, she closed her folder and was quiet for a long moment before she said, "We have a larger problem than one sergeant."
Marcus Tully, the reporter, had called me again on Thursday morning.
I answered this time.
"The story I filed is being updated," he said.
He sounded younger on the phone than he had seemed when he called the first time.
Uncertain.
"My editor pulled the anonymous source after the FBI contacted the paper yesterday.
The sourcing didn't hold up under internal review."
"What specifically didn't hold up?"
"The claim about foundation irregularities.
When we went back to verify, there wasn't anything there.
The source had—" He stopped.
"The source had given us a framing that the documents didn't actually support."
"What did the documents support?"
"A clean foundation with one large donor whose identity was obscured by the trust structure." A pause.
"That's not an irregularity.
That's standard practice."
"So you published a story built on a framing your source invented," I said, "without verifying whether the documents supported the framing."
A long pause.
"Yes."
"Who gave you my direct number?"
Silence.
"Mr.
Tully.
You've already told me your editor pulled the source because they didn't hold up.
You're updating the story.
You're on the phone with the FBI agent you wrote about without an attorney present." I kept my voice level.
"You are trying to do the right thing.
Help me understand the full picture."
Silence for another moment.
Then: "He said he was a Fulton County law enforcement liaison.
That was how he introduced himself.
He said he had documentation of a pattern of financial misconduct and that the story needed to be told before it was buried."
"What was his name?"
"He gave me a name.
I'm not sure now it was real." A pause.
"He said his name was Garrett Lyle."
I wrote it down even though I didn't need to.
Lyle had called the reporter himself.
He had sourced the story personally, using his own name.
Either he was supremely confident he was untouchable, or he had not anticipated that the story would fall apart within twenty-four hours and that the reporter would talk.
Both possibilities told me something.
The financial subpoena came back on the following Monday.
Callahan spread the highlighted sections across the conference table in Webb's office.
I stood across from her, Webb to my left, the Assistant U.S.
Attorney — a woman named Carla Fenn who wore her glasses on a beaded chain and had the focused patience of someone who had tried three hundred cases — to my right.
"Three client accounts," Callahan said.
"Same structure each time.
A public official, a private company, and Lyle Strategic Group in the middle.
The official steers a contract or a zoning decision or a regulatory approval.
The company pays Lyle's firm a consulting fee.
Lyle distributes portions of the fee through a series of LLCs." She turned a page.
"It's not complicated.
It's just hard to see unless you're looking at all three accounts at the same time."
Fenn tapped the page.
"What connects these three officials?"
"All three served on the same state infrastructure committee between 2019 and 2022," I said.
"All three received payments traceable back to Lyle's LLC structure during that period.
And all three are connected — directly or indirectly — to public safety contracts that were awarded without competitive bidding."
"Including contracts with Fulton County Sheriff's Department?" Fenn asked.
"Including those," I said.
"Mercer was not random.
He's been a Lyle asset for at least four years.
The body camera malfunction, the escalation, the call immediately after the swing — Mercer knew exactly what the play was.
He just didn't know he was using it against someone who was already investigating the man who sent him."
Webb looked at Fenn.
"How do you want to move?"
Fenn removed her glasses and let them hang on the chain.
"Carefully and completely.
I want Mercer first — his cooperation gives us Lyle's operational details.
Then we approach the officials.
Lyle last." She looked at me.
"The civil rights charge against Mercer — that stays separate from the corruption case?"
"Yes.
That's a standalone federal civil rights matter.
His actions against me don't need to be part of the corruption prosecution to be fully charged."
"Good." Fenn put her glasses back on.
"Let's build the indictment."
The next two weeks moved in a rhythm I recognized from other large investigations — fast internally, invisible from the outside.
Subpoenas.
Interviews.
Financial reconstruction.
A forensic accountant from Washington arrived on Wednesday of the second week and didn't leave until she had mapped every LLC layer in Lyle's structure on a whiteboard that covered an entire wall of the second conference room.
On the Thursday of the third week, we executed the first warrant.
It was not on Lyle.
It was on the smallest of the three officials — a former committee member named Raymond Ash who had retired from public service two years ago and was now running a landscaping business in Marietta.
The warrant was for financial records.
Ash opened the door himself, looked at the badge, and said, "I've been waiting for someone to come."
His attorney called Fenn's office the same afternoon.
The thread was pulling.
I was in my office at six that evening, working through the LLC documentation, when my desk phone rang.
Internal line.
"Reeves."
It was the front desk.
"There's someone here asking for you.
He doesn't have an appointment.
He says his name is Garrett Lyle and he'd like to speak with you directly."
I set down my pen.
"Tell him I'll be down in five minutes," I said.
I called Callahan first.
May you like
Then Webb.
Then I took the elevator down.
