The command center immediately began examining the messages on Whitmore's phone.
The unknown number had been used only twice.
Both messages were sent within minutes of the presidential motorcade operation.
The photograph appeared to have been taken from a camera positioned across the street from the eastern checkpoint.
The security team requested assistance from digital investigators to preserve the original data and determine what could reliably be established about the sender.
Marcus stood beside the main monitor.
Haynes approached.
"Do you think Carter was responsible?"
Marcus shook his head.
"Not enough evidence."
"But he gave Whitmore the instruction."
"That doesn't establish that he sent the messages."
Sergeant Miller entered carrying a folder.
"I've got the original briefing records."
He placed the folder on the table.
Marcus opened it.
The document contained the names of officers assigned to various checkpoints, emergency contact numbers, vehicle descriptions, and instructions for handling unauthorized individuals.
At the bottom was the name of Lieutenant Richard Carter.
Marcus examined the signature.
"Who approved this briefing?"
Miller answered.
"Carter's commanding officer."
"Was the briefing distributed electronically?"
"Yes."
"Who had access?"
Miller hesitated.
"Several supervisors."
Haynes looked toward the monitor.
"Then we need the access history."
The communications officer brought up a report.
"Agent Reed, we found an unusual login."
Marcus turned.
"What kind?"
"The original briefing was modified at 8:42 p.m."
"By whom?"
The officer enlarged the information.
The account belonged to Lieutenant Carter.
Miller frowned.
"That doesn't make sense."
"Why?" Haynes asked.
"Because Carter reported that he was at headquarters during that period."
Marcus looked at the timestamp.
"Can we verify his location?"
"We're checking."
The officer continued.
"The modification changed one paragraph concerning federal personnel at the eastern checkpoint."
Marcus leaned closer.
"What did it say before?"
The officer displayed the original version.
The instruction was straightforward:
All federal agents assigned to the presidential protective detail must be granted immediate access after standard credential verification.
The modified version was different:
Any unidentified individual claiming federal authority must be detained pending approval from local command personnel.
Haynes stared at the screen.
"That's not the same instruction."
"No," Marcus replied.
"Someone deliberately changed the language."
Sergeant Miller shook his head.
"I need to speak with Carter."
Marcus stopped him.
"Not yet."
Miller frowned.
"Why?"
"Because if he is involved, we don't want to alert him before the investigation team preserves the evidence."
The supervisor approached.
"Reed, we've received preliminary information about the suspicious vehicle."
Marcus turned.
"What have you found?"
"The Northbridge access card belongs to a former contractor named Victor Hale."
Haynes looked at the supervisor.
"Former?"
"He worked for the company for four years before leaving six months ago."
"Why did he leave?"
"His contract was terminated following an internal investigation involving unauthorized access to restricted facilities."
Marcus's expression tightened.
"Was he prosecuted?"
"No. The investigation did not produce enough evidence for criminal charges."
The supervisor displayed a photograph.
A man in his early forties appeared on the screen.
Short dark hair.
A narrow face.
A small scar near his left eyebrow.
Marcus recognized the silhouette from the surveillance footage.
"Is this the man near the sedan?"
The officer nodded.
"Preliminary facial comparison suggests a possible match, but it is not conclusive."
Haynes looked at the photograph.
"Do we know his connection to Carter?"
The supervisor opened another file.
"That's where things become interesting."
A list of financial transactions appeared on the screen.
Several payments had been made to a consulting company associated with Victor Hale.
The payments originated from a business account connected to a private security subcontractor.
One of the authorized signatories was listed as Richard Carter.
Miller stared at the screen.
"Lieutenant Carter?"
The supervisor nodded.
"That's correct."
Nobody spoke.
Marcus examined the dates.
The payments had begun several weeks before the presidential visit.
They had continued after Hale's contract was terminated.
The connection was significant, but it did not yet establish exactly what the men had planned.
Haynes looked at Marcus.
"Someone may have been preparing this operation for weeks."
Marcus nodded.
"And tonight, they used a local police officer to create a distraction."
He turned toward Whitmore, who was still sitting quietly near the door.
"Officer, I need you to understand something."
Whitmore looked up.
"Yes, sir?"
"You may have been manipulated. But you still made decisions without verifying information that could have been checked."
Whitmore lowered his head.
"I understand."
"Your mistake could have compromised the operation."
"I know."
Marcus paused.
"Make sure you tell investigators everything. Do not leave anything out, even if you think it makes you look bad."
Whitmore nodded.
"I will."
At that moment, the communications officer received another alert.
He looked at the screen.
Then his expression changed.
"Sir, Lieutenant Carter has just entered the police department's operations building."
Miller stood immediately.
"He's there?"
"Yes."
Marcus looked at the supervisor.
"Keep him under observation. Preserve the access logs."
Haynes reached for her jacket.
"Then I think it's time we had a conversation with Lieutenant Carter."
