Tracy was dropped off at Bensalem High School on the morning of March 7, 1983 by her mom’s boyfriend, Paul Greenwald. But Tracy never attended school that day and this was the last reported account of Tracy’s location. Tracy's mother, Jean Byrd, disappeared in early October of 1983. Her body was discovered in Blackbird State Forrest in Delaware. Her boyfriend, Paul Greenwald, was arrested for the homicide and committed suicide shortly afterwards in prison. He denied any involvement in Tracy's disappearance. Police have another suspect, a Bucks County, Pennsylvania man, but he has not been publicly named. She was 14 years old at the time.
