The Montgomery County State's Attorney's Office yesterday dismissed charges against three persons who were accused of kidnapping a 23-year-old member of the Rev. Sun Myung Moon's Unification Church in an alleged to effort to deprogram the Moon follower.

Charges were dropped against deprogramming experts Mark Conley, a county resident; Michael Dennis Mc Avoy, of New York City, and Paige Goulding Stetson, of Rye, N.Y., according to Deputy State's Attorney Timothy Clarke.

Deputy State's Attorney Timothy E Clarke said the state dismissed the charges because the original indictment failed to cite the proper date on which the alleged crime was to have taken place. When a Circuit Court judge last year denied the state's request to amend the indictment, Clarke said, "It was impossible to go forward with prosecution."

The case involved efforts to get Karen Mischke of North Carolina to renounce the religious beliefs she had developed in three years of membership in Moon's Unification Church. Mischke's mother, Anne Metsger, was also charged with kidnapping her daugther while Mischke was visiting relatives in Montgomery County. But in a highly unusual move, a grand jury last August withdrew its indictment against the mother and five other persons charged in the case.
