A member of a Roman Catholic religious order has been indicted by a D.C. Superior Court grand jury on five counts of taking indecent liberties with a minor child and seven counts of sodomy.

Brother Matthew L. Miles, a member of the Fathers and Brothers of the Sacred Heart headquartered in Hales Corner, Wis., was living at the St. Francis De Sales parish rectory at 2021 Rhode Island Ave. NE when the alleged incidents occurred, according to a source familiar with the case.

The source said Miles, 43, had once been assigned to work in the parish, but had been living at the rectory recently while studying at the University of Maryland.

The incidents listed in the indictment allegedly involved three boys, all aged 10 or 11, and spanned the period from late November 1981 until March of this year.

An affidavit filed in court said the alleged incidents became known after one of the boys told family members that Miles had molested him "and other children attending the learning classes and basketball activities at the rectory." The boy's father then called police.

Neither Miles nor the head of his order could be reached yesterday, and an official of the Archdiocese of Washington declined comment.
