Police have identified the body of a 21-year-old Edmonton woman found slain east of the city in a case that is being probed by the joint task force known as Project Kare.

The body of Brianna Danielle Torvalson was discovered Thursday morning in a rural area of Strathcona County. The medical examiner confirmed Friday she was slain, but police have not released the cause of death.

Police said Torvalson was known to them and led a high-risk lifestyle, but they stopped short of calling her a prostitute.

Investigators are appealing to anyone who may have seen anything suspicious in the area between Wednesday night and Thursday morning or those who may have been in recent contact with her to come forward.

Project Kare, a joint team of investigators from the RCMP and city police forces, has been probing more than 20 cases of dead or missing women since 1980.

Many of the women worked as prostitutes or were involved with drugs and other high-risk activities, and were found dumped in rural areas outside Edmonton.
