(WDIV) Warren police said DNA tests done on body parts that were found in a sewer last December confirm they belong to two different women.
Warren Police Commissioner Jere Green said Friday the victims' DNA doesn't match any in police databases and no missing persons reports have yielded any clues either.
"The fact that the body parts come from a different person concerns us and makes us want to be even more aggressive with this investigation," Green said. "We need some answers."
The body parts were found in a sewer line by work crews, first in August in Sterling Heights along 15 Mile Road just east of Maple Lane.
The parts didn't include bones or internal organs.
