There's a new wrinkle in the case of a man trying to use DNA evidence to reverse his 1994 Vermont murder conviction.
Lawyers for 50-year-old John Grega of Lake Grove, N.Y., say DNA evidence taken from the body of his dead wife Christine did not come from Grega, but from another, unknown male who was likely the real killer.
A prosecutor, however, says it may have come from skin particles left by someone else on an object Grega allegedly used in the attack at the condo they were renting in West Dover.
Windham County State's Attorney Tracy Kelly Shriver says she'd like to test the DNA of previous renters at the condo.
But she says those rental office records appear to have been destroyed by flooding from storm Irene.
