From the McMinnville Police Department Facebook Page:
Scam alert!!! Someone has been calling people claiming to be one of our Detectives and telling people there is warrant on them and to take care of the fines, they must purchase green dot cards and for them to call a number and provide he information of the card to pay off the fines. Please contact our department if this happens. This is a scam. We would never contact anyone and ask them to do this. Thank you!
