A judge has granted a Washington City woman guardianship over a 15-year-old girl from the polygamist border community of Colorado City, Ariz.

Fifth District Judge J. Philip Eves made the ruling after Deanna Johnson's father, Lavar Johnson, agreed to the arrangement in exchange for an affidavit filed by the girl's attorney being pulled from the court record.The affidavit was not made public.

The guardianship, granted Monday to Delsa Neilson, a relative, will allow Johnson to attend school in Utah. Neilson's relationship to the girl was not detailed.

The affidavit, filed by attorney Tim Anderson in support of the guardianship motion, purportedly contained allegations against Johnson and his family - allegations Johnson denies.
