EDMONTON — Police aren't saying if another body found near Edmonton might be linked to a possible serial killer working in the area.

The bodies of three other women were recently discovered in the same area near Leduc, Alta., adding to the total of dozens of Edmonton-area prostitutes missing and killed over the past four decades.

Last week, RCMP said they might be dealing with a predator targeting at-risk women.

Leduc RCMP say the latest remains were found on Monday in the town of Calmar, about 50 kilometres southwest of Edmonton.

Police say foul play has not been ruled out.

Last week, RCMP identified human remains found on a property south of Edmonton as Corrie Ottenbreit, a sex worker, who was last seen in Edmonton in May 2004.

The bodies of at least 30 prostitutes have been turning up in rural areas surrounding the city since 1975. Dozens more are still listed as missing. The cases prompted RCMP to create Project KARE in 2003, which collects identifying information on sex workers.

More than 1,200 Alberta women in high-risk lifestyles have registered with the system, which contains their name, address, DNA sample and a photo.

RCMP were able to identify Ottenbreit's remains with a hair sample she provided.

RCMP Staff Sgt. Gerard MacNeil, with Project KARE, told the Edmonton Sun in 2012 that he's convinced a serial killer is still on the loose, despite convictions in some of the cases.

The cases bear an eerily similarity to the Highway of Tears murders in British Columbia. At least 18 at-risk women have disappeared along a section of highway in the province.

It also parallels the case of Robert Pickton, who was found guilty of killing dozens of prostitutes from Vancouver's Downtown Eastside at his pig farm.
