DETROIT (WWJ)– Detroit’s Police Chief Ralph Godbee said Monday three of four women found dead in trunks of cars over the past week had profiles on a website.

“Where three of the four females have a connection to the website deals specifically with pre-arranged adult dating services or escort services,” Godbee said at a news conference at Detroit Police headquarters.

Godbee said it’s too early to say if the murders are the work of a serial killer, but he said meeting someone over the Internet can be “extremely dangerous.”

“We implore people to be careful and always let someone know exactly where they are going and who they are with, if you are arranging something, do it in public place.”

WWJ Newsradio 950’s Ron Dewey reported the area was quiet Tuesday morning, but police said they will be out patrolling the area throughout the day.
