DETROIT — Detroit police fear that a killer may be targeting escorts after finding that three of four women found dead in car trunks over the past week had placed sex-related ads on the same website.

Police Chief Ralph Godbee says authorities find the link "disconcerting."

At least 45 attorneys general raised concerns earlier this year about how the site,, polices ads for adult services.

Email and phone messages seeking comment were left for a lawyer Tuesday.

The latest victims were found Christmas morning, when Detroit firefighters discovered two badly burned bodies in the trunk of a car that had been set ablaze in a garage.

A joint funeral is planned for Thursday for the other two women, found dead Dec. 19. Police were withholding the names of latest victims.
