Greenwich police have been working for months to learn more about human bones discovered in the area of Helen Binney Kitchell Natural Park, and News 12 spoke with a leading forensics expert about what sort of evidence detectives are looking for.

Skeletal remains were found in the woods near some wetlands in April. Police are hoping a dredging project in Binney Pond will reveal evidence that will help them identify the skeleton and determine how the person died. Detectives believe the body belongs to an adult who may have died as recently as this year.

Dr. Henry Lee, of the Henry C. Lee Institute of Forensic Science at the University of New Haven, explains that while some bodies are never identified, investigators still have many options, including DNA, facial reconstruction and even encouraging the public to help.

"The forensic anthropologist and the forensic artist working together may have the possibility to do facial reconstruction," Lee says. "Then from facial reconstruction, there's the public help -- the public may come forward and recognize this person."

Greenwich police are also waiting for a report from the medical examiner's office. They say that will help them determine their next step.

Police say crews have already begun preparing the area around the pond that will be dredged.
