A church deacon charged with killing his young neighbor and burying her partially clad body in his basement was ordered Thursday to undergo psychiatric testing, while police began excavating his yard in a search for more bodies.

A crowd of as many as 300 jeering Kingston residents gathered outside the courthouse as Henry Meinholz, 52, was brought in for his arraignment. Some shouted, "Hang him! Hang him!" as several police officers led the suspect inside, where he pleaded innocent.Meinholz, a bookkeeper for a lumber company, was arrested Wednesday shortly after authorities investigating the disappearance of 13-year-old Melissa Benoit discovered a body in the cellar of his Main Street home, almost directly across the street from the town police station.

The girl's disappearance sparked a massive search by several hundred volunteers and a nationally televised plea for her safe return by her mother, who appeared on the program, "America's Most Wanted."
