Officials hope DNA samples from tattooed chunks of human flesh discovered in a suburban Detroit sewer last month will help them determine the identity of the person they came from.
The Macomb Daily of Mount Clemens reports officials recently sent the samples to the University of North Texas, which has a DNA database of unidentified remains.
The 10 body parts were found Aug. 15 by contractors clearing debris from a pipe in Sterling Heights. Authorities believe they belonged to a Caucasian.
The parts didn't include bones or internal organs.
Police don't know if the person was male or female. Investigators have said the tattoo on the flesh appears to have been inked at least 15 to 20 years ago.
Authorities also have been going over missing persons reports.
