ANNAPOLIS, Md. (AP) — A private school in Maryland confirmed Monday that 10 adults in positions of authority engaged in sexual misconduct or inappropriate relationships with students from the 1970s through the early 1990s, and that the school failed to protect students from them. The Key School said at least 16 former students were subjected to the abuse. Officials there released the report on the school's website after an investigation that began in April, initiated by the school.
