"The case header makes it look like one continuous recording," Lena said. "But the underlying file history doesn't support that. This second clip was brought in later and attached to the original incident."
"Could the camera have restarted?" Mercer asked.
"A restart would leave its own sequence and source history. There isn't a matching record for that here."
"Could a technician have converted the video to a different format?"
"A conversion could explain some file changes," Elise answered from the adjacent workstation. "But it wouldn't explain why the supposedly original segment entered the system after the detention report had already been created. We'd expect a processing record, and we haven't found one."
Rebecca stood behind them. "None of this proves that the access card wasn't found."
"Agreed," Maya said. "We're not deciding that yet. We're identifying which portion of the evidence can be tied to the source recording and which portion can't."
Maya asked for Nathan's original statement. It described the afternoon of his detention in uncomfortable detail. He had arrived at a municipal service building to service environmental controls. His temporary work pass allowed him into a maintenance corridor, but not the rooms holding confidential city records. While waiting for access, he noticed a terminal in an adjacent workspace displaying vehicle histories unrelated to his assignment.
He had made a casual remark to a supervisor about why those records were open. Several days later, he was stopped at the service entrance, searched, and accused of carrying a restricted card he insisted he had never seen.
Nathan had not written like someone trying to impress a court. His complaint included ordinary details: the plastic handle of his tool case digging into his palm, the officer asking him to take off his work gloves, the small group of other contractors watching from the parking lot. He wrote that he had tried to tell the officer the card was not among his belongings before the search, but the officer kept returning to the alleged discovery. The complaint ended with a line Maya read twice: I asked them to check the whole recording, because I thought the video would show exactly what I had done.
Lena's handwritten notes began the day after that complaint. She had checked the system and observed an original continuous-source entry. She did not claim she had watched the entire video. Instead, she had recorded the existence of a file with a particular identifier, along with the time it appeared in the archive. Later, when she returned to look for the uninterrupted source, the entry had disappeared from ordinary search results. An official export remained, but it was not the same file she remembered.
"Why did this matter enough for you to keep coming back?" Maya asked.
Lena removed her glasses. "My father worked as a clerk at a county courthouse. He used to tell me that paperwork might look boring until someone needed it to prove they had been telling the truth. Nathan came in with an argument that depended on a recording. When the recording changed, he became the unreliable part of the story. It bothered me."
"Did you tell Nathan?"
