It was not a cold case in the traditional sense. Gacy admitted to the slayings and was convicted by a jury. But Moran and others knew if they had the victims' bones, they could conduct genetic tests that would have seemed like science fiction in the 1970s, when forensic identification depended almost entirely on fingerprints and dental records. After autopsies on the unidentified victims, pathologists in the 1970s removed their upper and lower jaws and their teeth to preserve as evidence in case science progressed to the point they could be useful or if dental records surfaced. Detectives found out that those jaws had been stored for many years at the county's medical examiner's office. But when investigators arrived, they learned the remains had been buried in a paupers' grave in 2009. "They kept them for 30 years, and then they got rid of them," Moran said. After obtaining a court order, they dug up a wooden box containing eight smaller containers shaped like buckets, each holding a victim's jaw bones and teeth. Back in June, Moran flew with them to a lab in Texas. "They were my carry-on," he said. Weeks later, the lab called. The good news was that there was enough material in four of the containers to provide what is called a nuclear DNA profile, meaning that if a parent, sibling or even cousins came forward, scientists could determine whether the DNA matched. But with the other four containers, there was less usable material. That meant investigators had to dig up four of the victims. Detectives found them in four separate cemeteries and removed their femurs and vertebrae for analysis. At a meeting last week, the men who investigated and prosecuted Gacy reminded the sheriff that many victims were already lost when Gacy found them. "I can almost guarantee you that one or two of these kids were wards of the state," said retired Detective Phil Bettiker. "I don't think anybody cared about them." Most were 17 or 18 years old and had been "through God knows how many foster homes and were basically on their own." Dart doubts that all eight victims will be identified. But he is confident the office will be able to give some back their names. "I'd be shocked if we don't get a handful," he said. "The technology is so precise."
