A man convicted 21 years ago of child abuse involving satanic rituals at a day care he ran with his wife has been freed amid questions about the case's evidence.

Dan Keller was released on bond Thursday, about a week after the release of his now ex-wife, Fran, who was imprisoned on similar charges.

The district attorney's office in Travis County, which includes Austin, has agreed that the physical evidence against the couple is faulty.

Both were convicted in 1992, after therapists testified that they helped three children recover memories of satanic rituals and sexual abuse at a preschool the Kellers operated out of their home.

A doctor originally testified that internal lacerations on one child were evidence of abuse. He now says they were actually normal physiology.
