Immunity offered in case of missing woman

JOLIET, Ill., March 6 (UPI) -- Illinois prosecutors offered immunity 17 months ago to a man whose testimony they sought in the case of a missing suburban Chicago woman, a document reveals.

A copy of an agreement drawn up in the disappearance of Stacy Peterson of Bolingbrook, Ill., indicates Thomas Morphey was offered immunity in exchange for his testimony against Peterson's husband, Drew, the Joliet (Ill.) Herald-News reported Friday.

Will County State's Attorney James Glasgow signed the accord but sources told the newspaper Morphey has never appeared before the grand jury investigating Peterson's disappearance.

Morphey had helped Drew Peterson carry a blue barrel out of the Peterson home before Stacy Peterson was reported missing, says the Herald-News.

Drew Peterson is the sole suspect in the investigation of his wife's disappearance.

Authorities are also investigating the 2004 homicide of Peterson's third wife, Kathleen Savio.
