Prosecutors in Detroit have dropped charges against a man accused of moving the bodies of four women found in cars last December.

But James Brown is not off the hook. Macomb County assistant prosecutor Bill Cataldo says his office is taking over the case because it has connections to that county. He appeared in court Wednesday and said fresh charges are in the works.

Brown remains in custody.

The bodies of Demesha Hunt and Renisha Landers were found Dec. 19 in a car trunk in Detroit. Six days later, the bodies of Natasha Curtis and Vernithea McCrary were found in a burning car. Three of the women had placed ads for escorts online.

Detroit police have identified Brown as the "main culprit." He was arrested May 1.
