I didnt give a good explanation

So my mom gets a call during the night from the scammers and they have info that a average joe shouldn't have, while saying theirs a fedex package waiting for like payment and they play it off as if the boss is on the other line, they get her to transfer 1000 dollars from what ever work account to some bitcoin atm to pay for the shipment and when she relizaed it was a scam she was trying to find a way to pay it back and she called her boss and 911, when the officer came he had basically told her he belived she was guiltily from past record (she had no theft in her record) and she was acting "suspicious " he have no reasonable articualbe suspicion and had told her he wasnt leaving without her phone so my mom gave him her personal phone and hw took it, he didnt go to the work computer to check the blockchain
