The process, called Phenotyping, uses a victim’s DNA to approximate his or her face — even if their body is found without a head.

The department is using the new technology for the first time in an effort to identify the victims in two unsolved homicides from 2005 and 2015.

“Still requires a lot of old fashioned gum shoe detective work,” Assistant Chief Patrick Conroy said Wednesday. “These are just leads that help us go in the direction we need to go.”

In the 2005 case, a human torso was found on July 26 at Cooper Transfer Facility on Maspeth Avenue in Brooklyn. Days later, a human skull was found in a garden on Stuyvesant Avenue in Brooklyn. It’s believed the body was placed in a dumpster on Gates Avenue, then moved to the transfer facility, police said.
