The Sterling Heights police department say that they are treating the case as a homicide until proved otherwise, according to M Live. There is a possibility that these body parts are discarded medical waste that somehow made it into the sewer.
Three pieces of human body parts that measured 2-by-2 inches were what the workman discovered. The parts are undergoing DNA testing to try and identify who the person was that these parts came from.
USA Today is reporting the body parts as being "fatty tissue and skin." The latest discovered body parts had no markings on them, making them even harder to identify. In the previous two incidents the body parts came from white woman.
The body parts found in Sterling Heights last year had tattoos, authorities say the parts were from a large woman and that the tattoos looked to be 15-20 years old. The picture of the tattoos is above. Police released the picture in hopes someone might identify the tattoo.
No appendages or organs were ever found in all three incidents. Lt. Kevin Reese from the Sterling Heights Police Department expressed that these cases are so frustrating because the pieces are small enough to be flushed down a toilet.
In August of 2012, partial remains were found in a sewer in the same area, Sterling Heights. Testing on the August 2012 discovery of body parts showed the remains came from a woman, but not the same woman whose body parts were found in December of 2012.
The unidentified woman’s partial remains in December were found in the sewer lines of nearby town of Warren. This appears to be an on-going problem. It could be that the culprit is someone who is improperly disposing of medical waste, or someone trying to hide pieces of people that were victims of a crime.
So far the newest body parts were not identified as male or female as of yet. These small pieces are undergoing DNA testing in hopes of putting some light on who they belong to.
