Autopsy inconclusive in death of 2nd B.C. escort

The autopsy results for New Westminster, B.C., escort Karen Nabors, who was found dead in her apartment on Sunday, are inconclusive, police say.

"As the cause of death is still unknown, further testing by the pathologist will be required and toxicology results are pending," said a statement issued by Integrated Homicide Investigation Team spokeswoman Sgt. Jennifer Pound on Wednesday.

Nabors, 48, was the second sex-trade worker found dead in the apartment building in the past two weeks, sparking concern and a public warning by police that someone may have targeted the two women.

Jill Lyons, 45, was found dead in her apartment two weeks ago. Police say evidence initially pointed to suicide so they did not issue a public warning at the time. The autopsy of Lyons was also inconclusive and police are still awaiting the toxicology results.

But after Nabors was found dead in her apartment on Sunday, police issued a warning on Monday afternoon, warning those who work in the sex trade to be vigilant.
