Residents of Blue Earth County have been scammed out of thousands of dollars over the phone in recent days. In the first case, a woman received a call from someone claiming to be Canadian law enforcement. The caller identified the woman’s grandson by name and told her to wire money to secure his release. She ended up sending over $3,100 to California. Two additional fraud cases then occurred over the weekend. These calls were made to Blue Earth County businesses. In each case the caller used the name of an actual Blue Earth County Sheriff’s Deputy. They then claimed that an employee of the business was under arrest and they would need to wire money. In the first case a person at the business wired $700. In the second case, the woman in question walked into the business before the potential victim could wire the money. Authorities say that in all three cases, the callers had done their research and had actual names connected with victims. Anyone who receives such a call is encouraged to take the time to verify the information.
