The remains of an approximately 25- to 45-year-old woman were found in a wooded picnic and rest area located between Guelph and Rockwood in August 2005

The Wellington County Ontario Provincial Police says it continues to investigate a suspicious death in which a woman’s body was discovered 13 years ago near Rockwood, Ont.

The remains of an approximately 25- to 45-year-old woman were found in a wooded picnic and rest area located between Guelph and Rockwood on Aug. 28, 2005.

In a recent press release, OPP said it is believed the woman had been dragged a short distance into the wooded area approximately one month before the remains were discovered. A Woods brand sleeping bag was draped over the remains.

OPP Investigators believe the circumstances surrounding the death are suspicious and consider foul play was involved.

The OPP has never been able to identify the woman. She was approximately 5-feet, 6-inches tall, weighed about 130 pounds and had light brown hair. No personal identification was found and the clothing items she was wearing were purchased in the Montreal area.

An autopsy revealed no recent injuries, but the woman had past injuries to her face — including a broken left cheek, nose and left eye socket — that occurred some time in her past and had healed. Those injuries would have left her with a visible facial deformity, said the OPP.

As a result of the injuries, the woman lost two upper teeth on the left front and wore a two-tooth partial plate.

"In spite of numerous tips from the public and extensive media coverage over the years, the identity of this woman - and her killer - remains unknown," said Randy Gaynor, OPP detective inspector. "We are confident family members, friends, former colleagues or someone with knowledge of her past injuries can come forward to assist with this complex investigation."
