A Vermont judge has ordered a new trial for a man convicted of murdering his wife in 1994, after newly analyzed DNA evidence raised questions about the case.

Fifty-year-old John Grega, formerly of Lake Grove, N.Y., on Long Island, was serving life without parole in the rape and murder of his then-31-year-old wife Christine while they were vacationing at a West Dover condominium.

Last month, his lawyers filed a motion to have his conviction thrown out, which potentially could have set him free. A hearing had been set for Friday.
