On April 24, 2024, an employee at Circle K gas station received a call from an individual named Sam. Sam identified himself as the regional manager for Circle K.  Sam advised the employee to remove most cash for both cash registers and the safe and deposit the funds at the Bitcoin KIOSK inside Circle K.

The employee followed directions and sent an initial payment of $400 of Bitcoin to the above address. The net transfer was approximately .0055 BTC valued at $367 USD. This transaction occurred on 2024-04-23 23:44:55.

The employee then became skeptical and decided to not engage in any additional transfers, but he did not report his concerns to his shift manager.
