The National Parole Board has revoked day parole — for a second time — for a P.E.I. convicted killer after he was found intoxicated and harassing a woman.

Fred Sheppard has been returned to an Alberta prison after police found him harassing a woman in downtown Edmonton in May. Sheppard swore at police and tried to punch one of the officers.

He was released on day parole in February after completing eight years of his 10-year sentence for manslaughter. One of the conditions of his release was to abstain from alcohol.

Sheppard, from Cardigan, P.E.I., was convicted of killing his wife, Kimberley Anne Byrne, in December 2000. He beat her to death, using his hands and feet, while their young son was in the house.

The charge was reduced from murder to manslaughter because the courts decided Sheppard was too drunk to know what he was doing.

When Sheppard was first granted parole in 2004, he was returned to prison the next year after violating the conditions of parole by drinking.

Sheppard will be released from prison on May 20, 2010. He will be eligible for parole again in one year, but parole board officials say the this latest incident will make that unlikely.
