Detective Amber Shirley with the Natchitoches Parish Sheriff’s Office High Tech Crime Unit spoke to the Natchitoches Lions Club about scams the public should be on the lookout for. Financial crimes are the number one crime in the nation and Shirley recommends citizens be on their toes for any suspicious phone calls they may receive regarding lotteries, IRS, people posing as a grandchild and asking for money to stay out of jail, sweetheart scams involving online dating, reshipping scams and credit card scams.
