iPhone 12 Theft
The group accomplished this by secretly putting iPhones into various packages and removing them at the last minute. After the weight differences were detected, Amazon installed hidden cameras to investigate the issue.
That is, someone, probably an accomplice, bought something relatively cheap on Amazon, and before it was sent they exchanged the contents of the package for an iPhone.
Three were arrested upon leaving their job, one was arrested during work, and the fifth voluntarily surrendered. They are currently awaiting trial.
