WOODBURY - The family of slain Nassau County Police Officer Michael Giglio is urging the state parole board to keep convicted killer John MacKenzie in prison.

MacKenzie got 25 years to life after he was found guilty of shooting Giglio during a West Hempstead burglary back in 1975.

MacKenzie has been denied parole six times since 2000, when he first became eligible. He told News 12 Long Island from prison in 2000 that he was remorseful and had changed.

"Every two years we do this and every two years it resurfaces all of our pain and anguish," says Giglio's daughter, Regina. "Every two years the wounds get reopened. The horror of what we lived with so many years ago."
