Cold Case Files

Name : Homicide of Rhona Margaret DUNCAN (Age 16)

Location : North Vancouver, British Columbia (BC)

Details : On the evening of July 16th 1976, 16 yr. old Rhona DUNCAN and some friends attended a house party on East Queens Ave. in North Vancouver, BC.

There were about 60 teenagers from school at the party. At about 1:00 A.M. Rhona and her girlfriend, Marion Bogues decided to walk home. They left with Bogues boyfriend, Owen Parry, and DUNCAN’s boyfriend, Shawn Mapoles. The boys went there separate ways as they got close to their homes and Bogues and DUNCAN continued on by themselves. DUNCAN and Bogues parted company near Bogues residence. Rhona DUNCAN was five blocks from her house. It was about 2:45 A.M. at this time.

At about 3:00 A.M. a neighbor of DUNCAN’s heard the sound of a male and female arguing outside of her residence. She woke her husband and he went out to investigate. The husband went to the back of his residence and heard the male and female arguing. He yelled, “What’s going on here?” and the noises stopped. He did not hear anything else so he went back to bed. The neighbor lived three houses away from the DUNCAN residence.

DUNCAN’s partially clad body was located the next morning at about 09:00 a.m. in some long grass behind the neighbors garage. She had been raped and strangled. Cause of death was determined to be from manual strangulation.

Investigators interviewed all of DUNCAN’s friends and acquaintances. Numerous polygraph examinations were conducted but the case remained unsolved. In 1998 with the advances in DNA technology a DNA profile was obtained of Rhona DUNCAN’s attacker.

A list of 172 males consisting of all of DUNCAN’s acquaintances and all of the suspects on the file was compiled. Investigators have obtained DNA samples from the vast majority of the subjects on the list and compared them with the suspect DNA with negative results. All of the higher priority subjects on the list have been eliminated. Many of the remaining subjects are either deceased or have not been located.

Contact : Anyone having information is asked to contact Sgt. Gerry Webb of the North Vancouver Detachment Serious Crime Section at 604-983-7417 or call Crimestoppers at 1-800-222-8477.
