Investigators from Durham Regional Police are reexamining the case of Noreen Anne Greenley, who disappeared 60 years ago at the age of 13. A new theory has emerged suggesting that Greenley may have left voluntarily instead of being abducted. On September 14, 1963, Greenley was with her friends after a bowling outing in Bowmanville, Ontario. They had dinner and tried to catch the bus home, but Greenley never boarded the bus. In 1968, Greenley’s father came forward with information suggesting that she had left home on her own. However, her father passed away shortly after providing this information, limiting the investigation into that theory. Recently, notebooks written by a former Bowmanville police constable have been discovered, shedding new light on the case. The notebooks mention a call for service in Oshawa, where two girls were reported to be staying—one of them pregnant and afraid to go home. However, these girls were never located. The notebooks also mention the name Bert Quinney and suggest that Greenley traveled to Oshawa and Whitby after her disappearance. Investigators are looking for a couple named Mary and Gary Benson who may have helped Greenley during this time. It is also believed that Greenley and a friend may have traveled to Rochester, New York, on a 40-foot cabin cruiser named the Mary Bell, captained by a man named Franco. After staying in Syracuse, New York, Greenley is believed to have settled in the United States, possibly giving birth to a baby boy. As part of the investigation, police have obtained five phone numbers listed on an old long-distance card and are asking for anyone who recognizes the numbers to come forward. This new information has led investigators to consider the possibility that Greenley left voluntarily and did not intend to return to Bowmanville. Greenley’s family, who attended a recent press conference, are hopeful that this new avenue of investigation will bring forth new information about her disappearance. Anyone with information is urged to contact the Durham Regional Police.
