NEW YORK (AP) — A disgraced dean of St. John’s University accused of using students as personal servants was found hanging in her apartment Tuesday, dead of an apparent suicide one day after she testified in her own defense at her criminal trial, a law enforcement official said.

Cecilia Chang’s body was discovered hanging from a folding ladder that leads to her attic in her Queens home Tuesday morning, said the official, who was not authorized to speak publicly because Chang’s family had not been notified and thus spoke to the AP on condition of anonymity.
