Call Oklahoma City PD, preferably the detectives division and ask if he is employed there, but make sure you explain the situation, you may not get very far without them knowing the whole reason of your inquiry. If he is or was employed there somebody should know him. He may be retired based on his commission date. Offer to send them the picture of the ID, credentials, and badge. He’s either unknowingly being used as a face to scam people or he’s got no ethics as a police officer, but more than likely judging by the Zelle name, it’s a scammer.
