PROVIDENCE, R.I. (AP) — Three men have been sent to prison for their roles in a so-called grandparent scam that cheated more than a dozen Rhode Island residents between the ages of 79 and 94 out of more than $300,000 combined, federal prosecutors said.

The defendants contacted the victims and pretended to be a relative or an attorney who needed cash to make bail payments for a family member, often a grandchild, who had been arrested, U. S. Attorney for Rhode Island Zachary Cunha said in a statement Monday.

The victims were told to provide the cash to a courier who would be sent to their home. At least 14 Rhode Island residents were victimized.

Diego Alarcon, 22, of Union City, New Jersey, was sentenced Friday to 2-1/2 years in prison. Bryan Valdez-Espinosa, 22, of Union City, New Jersey, was sentenced to the same term earlier this month.

Jason Hatcher, 40, of New York, was sentenced in November to 2 years and 9 months in prison.

All three pleaded guilty to wire fraud charges. In addition, Hatcher pleaded guilty to aggravated identity theft.

The men were also ordered to pay restitution.

Prosecutors previously said the defendants were caught only after a family member intervened in one of the scams.
