An autopsy was conducted Tuesday on the remains of a woman found on the side of Highway 16, east of Prince George, B.C. on Friday.

While no cause of death has been released yet, police say they are treating the case as a suspicious death.

Prince George RCMP have said they will not release the identity of the woman until the next of kin is identified.

At least six women, mainly Aboriginal teens, have gone missing over the last decade on the stretch of highway known as the so-called Highway of Tears.

"This is just ringing that bell a little bit louder," said Clairie Johnson, of the Prince George Sexual Assault Centre told CTV Vancouver. "I think we're all … just kind of waiting and dreading what we're going to hear."

One of the most high-profile cases involved 25-year-old tree planter Nicole Hoar, who went missing while hitchhiking on the stretch of highway in 2002.

Police have said they still don't know whether the cases of the missing women are linked.

"To my understanding, they haven't been connected yet. They are all single investigations," said Const. Gary Godwin of the Prince George RCMP.

Meanwhile, it was a day of remembrance for dozens of women who were murdered and went missing from Vancouver's gritty downtown Eastside.

About 800 people marched through the streets of one of Canada's poorest neighbourhoods for the memorial march that is held every year on Valentine's Day.

Robert Pickton has been charged with first-degree murder in the deaths of 27 of the women. He pleaded not guilty to 27 counts of first-degree murder at the end of January.

Some elders and family members attired in traditional First Nations garments beat drums and sang native hymns as they marched. Others stopped along the route at sites where some of the victims are known to have died, to lay roses and conduct a cleansing ceremony.

Lori-Ann Ellis of Calgary told The Canadian Press she was marching in the procession to honour her slain sister-in-law Cara Ellis.

"We want people to remember that these are human beings and they cannot just pass away or be murdered and go missing and not be remembered," Ellis said, of her third consecutive year marching in the procession.

"As long as there is breath in my lungs we will come every year," said Ellis.

Pickton has been charged in the death of Ellis, who was last seen in 1997 when she was 25.
