LEE COUNTY, Fla. - A 79 year old grandmother is out her life savings after a scam, investigators say, thats targeted towards military grandparents.

Rosemary Maneri says she got a call Tuesday afternoon from a man claiming to be her grandson.

According to deputies, the suspect said he was her grandson, who is in the Army Reserve, and was injured in a car crash in the Dominican Republic. They demanded cash to help with medical and transportation needs.

Maneri says they told her to use MoneyGram to send the cash out of the country.

The 79 year old does not know how the suspects obtained her phone number or her grandson's personal infomration.

According to the FBI, this is a scam similar to one they have on record. The agency's website cites the crime as a common scenario for taking financial advantage of the elderly; "We’ve also seen military families victimized: after perusing a soldier’s social networking site, a con artist will contact the soldier’s grandparents, sometimes claiming that a problem came up during."
