New DNA evidence has helped Cook County investigators identify another victim of serial killer John Wayne Gacy.

Cook County Sheriff Tom Dart announced Tuesday that William George Bundy has been positively identified as one of Gacy’s victims. Bundy was reported missing in 1976, and was possibly lured to Gacy with the promise of construction work.  He was 19 at the time of his murder.

Bundy had previously been identified as Victim #19 - the nineteenth body to be removed from the crawlspace beneath Gacy’s Northwest Side home, three days after Christmas in 1978.

Two of Bundy’s surving siblings submitted to DNA tests after Dart’s office launched a national campaign in October to put names to eight of Gacy’s unidentified victims. Investigators had exhumed remains from each of the victims, and were looking for family members who could help make a DNA match. DNA from the cheek of Bundy’s siblings helped positively identify him as a victim, Dart said.

“I know that the sorrow will eventually go away, and I’ll have a place to visit him,” said Laura O’Leary, Bundy’s sister.

Bundy was a talented gymnast with lots of friends and female admirers, O’Leary said. She last saw him in 1976, when he left home to go to a party but never returned.

Twenty-six of Gacy’s 33 victims have now been identified.

In October investigators discovered that 53-year-old Harold Wayne Lovell, thought to have been a Gacy victim, is alive and has been living in Florida.

Gacy was executed in 1994 for the murders.
