John Wayne Gacy`s blood may solve old murders

CHICAGO (FOX 32 News) -

John Wayne Gacy is one of the nation's most notorious serial killers and now his name continues to haunt families and investigators looking for answers to unsolved murders.

Investigators have long suspected Gacy may have murdered more than the 33 young men he was convicted of killing. Now, these developments with Gacy's blood may make it possible to solve other murder mysteries.

"We found vials of his blood in the boxes that we were going through," says Cook County Sheriff Tom Dart.

Now that blood, and the DNA profile of John Wayne Gacy is part of a national DNA database that any police agency can tap into.

"If a jurisdiction had long ago submitted DNA from a crime scene, it would have had nothing to match against if in fact Gacy was the one who killed him," Dart explains. "So, by putting the DNA in there, anybody who's already submitted DNA from a crime scene might get a match as of today."

During Gacy's killing spree in the 1970's, he murdered and buried the bodies of 26 young men under his house. Seven others were disposed of elsewhere.

Sheriff's investigators say they have records that show during that time frame Gacy also traveled to 12 other states, and Ontario Canada, fueling speculation there may be more victims.

Karen Conti was on Gacy's death row defense team. She says he never told her he killed anyone, but, "he was killing young men in his house, burying them under the property, and here he had full reign, he was in the rural areas, he was in areas where no one knew who he was, and it's certainly possible that there are other victims," says Conti.

In fact, while police were trying to track down leads and identify the eight unidentified bodies found at Gacy's house, they traced one ID to a man alive in Florida who offered a chilling Gacy story.

"He then informed us that back in the 70's Gacy was down in that state, and Gacy tried killing him," says Dart.

The irony is that under state law Gacy's blood could not be sent to the lab for DNA profiling, but a cold case detective discovered a loophole.

Only since the year 2000 have convicted killers been required in Illinois to submit DNA samples. So, one of the cold case detectives had to find a work-around to get Gacy's blood into the national database.

"Homicide victims' blood gets sent to the State Police Crime Lab, they develop a DNA profile and it gets uploaded to be compared against crime scene database," says Cook County Sheriff's Police Det. Jason Moran. "I also recognized, immediately that Gacy was a victim of a homicide cause he was executed."

Gacy's trial attorney Sam Amirante does not think there are other victims out there, because while Gacy admitted to 34 murders, he never told Amirante of any others even when asked.

Because of the Gacy developments, other killers convicted before the law--which was changed in 2000 to require DNA samples--will have their DNA added to the national database, raising the possibility that additional cold cases could be solved.
