A California woman was sentenced to 21 months in prison for receiving disability payments from Hawaii for her father, even though he died in 1990.

Lynsie Williams, of Redlands, Calif., was sentenced Thursday in federal court in Honolulu.

Court documents say her father Edwin Callison qualified for Hawaii disability benefits when he was injured in 1976 at his job at the Kauai Humane Society.

He died in California in 1990 but Williams continued collecting his benefits.

According to a plea agreement, Williams deposited nearly $400,000 in a joint account and forged documents when Hawaii officials wanted to verify her father was still alive.

Assistant U.S. Attorney Larry Butrick says she’ll need to pay that back to the state and must also perform 300 hours of community service.
