"I will testify under oath," she said. "I am not asking anyone to treat my rank as proof. I am asking that the records be examined and that the witnesses be heard without interference. Our department has a duty to cooperate with that process, whether the outcome is comfortable or not."
A reporter asked whether she feared retaliation. Hang answered that she understood the professional risk but would not comment further about internal personnel matters while the investigation remained active. She looked briefly toward Kesha and Zara before stepping away. The movement was small; to Kesha it meant that someone inside the system had finally decided to attach her name to what she knew.
Castellano had remained inside the building despite the growing attention. He was watching the press feed on a monitor near the ceremony offices, the medal still hanging from his uniform. His first impulse had been to call the department's communications director and demand that the speakers be described as hostile to police. Then he heard Hang identify the missing phone and realized that whatever she had found might be beyond the reach of departmental messaging.
A staff member approached and asked him to remain available for a conversation with federal investigators. Castellano demanded to know why. The staff member said he had been instructed to pass along the request and could not answer questions about the investigation. Castellano pushed past him toward a side corridor, moving faster than he intended.
At the end of the corridor stood two federal agents. They were not there because the crowd had demanded an arrest. Their team had been executing a coordinated series of warrants that morning after prosecutors obtained judicial authorization based on evidence gathered over the preceding weeks. One agent displayed identification and addressed him by name.
"Lieutenant Owen Castellano, we have a federal arrest warrant for you," the agent said. "You are being taken into custody in connection with an ongoing investigation. You will have an opportunity to speak with counsel."
For a moment Castellano stared at them as if the words belonged to somebody else. Then he glanced back toward the auditorium where his photograph had been projected above a list of career commendations not an hour earlier. He looked at the medal, the neat line of his uniform, and the corridor that had suddenly become the last place he would walk as a free officer.
The agents secured him without violence. Farther across the city, other teams were taking steps to preserve records and detain additional suspects under separate warrants. Marcus Trent and several associates would face questions about the bombing, evidence access, and the Brooks incident. The allegations were serious, but investigators understood that arrests began a legal process; they did not replace trials or prove every charge by themselves.
