BRISTOL, R.I. (AP) — The Rhode Island Veterans Home must pay back millions of dollars to dozens of residents who federal investigators say were improperly billed for care.

Veterans Home spokesperson Meghan Connelly says the state owes $5 million after the U.S. Department of Veterans Affairs found that the home had improperly billed some residents for years.

Connelly said 56 current and former residents were impacted and 30 of them have since died.

She says the state will refund the next-of-kin or estates of the veterans who have died.

The investigation was launched this year following an anonymous complaint.

Investigators found that some veterans were inappropriately charged certain fees.
