The sheriff has just released a photo of a fraudulent lottery certificate that's been sent to some victims.
Others are targeted through phone calls, emails, faxes and letters telling them about their jackpot winnings.
To collect the jackpot, victims are asked to send money through Western Union or a cashier's check to a foreign address.
An 80-year-old victim lost $90,000, and a 74-year-old victim lost $82,000.
The sheriff's department reminds residents that you cannot win a lottery without having entered one. Also, there are no fees to collect winnings from legitimate lotteries.
