Auction House, basement.
Because the bandits had blown open the basement wall and then used it as an escape route from the auction venue, this place was thoroughly blocked off by the investigative department.
However, since this wasn't a homicide scene and the bandits had already been captured, the forensic investigators from the department finished up rather quickly.
Since there were no innocent civilians injured during the incident and the only deaths were either bandits or international criminals, the investigative department was somewhat casual in their evidence collection.
They basically wrapped up as soon as they finished taking pictures, and after inspecting the location once or twice, the investigation concluded, even the quarantine tape was taken down.
The staff of the First Auction House were also back on site, beginning to tally the number of collections.
But as they counted, they were suddenly stunned.
Because "Heart of the Ocean" was missing.
