LESTER HOLT, anchor: We're back now with new developments in a story we first told you about a few weeks ago, the new effort to identify victims of infamous serial killer John Wayne Gacy . Tonight there's resolution for a family left wondering for decades what happened to their son and brother after he walked out the door one night and never returned. More now from NBC 's Kevin Tibbles .
KEVIN TIBBLES reporting: After more than 30 long years, a break in the case involving one of America 's most notorious mass murderers.
Mr. TOM DART (Cook County, Illinois, Sheriff): Victim number 19 is never going to be known by a number anymore.
TIBBLES: When Chicago police uncovered the horrors hidden in the crawl space of John Wayne Gacy , eight of the brutal killer's 33 victims remained unidentified, until now. Thanks to advancements in DNA technology, investigators have determined one of them, victim number 19 , was a 19-year-old young man who disappeared in the fall of 1976 by the name of William Bundy .
Ms. LAURA O'LEARY: All my girlfriends wanted to date him. They didn't ever come over for me, only for him.
TIBBLES: Laura O'Leary is Bundy 's sister.
Ms. O'LEARY: I remember him leaving that one night saying he was going to go to a party and that was the last time I saw him .
TIBBLES: Gacy lured his victims, young men between the ages of 14 and 22, to his home where they were sexually assaulted and murdered. Authorities in Chicago sent the remains of those still unidentified to this lab in Texas in hopes that they could be named.
Mr. DART: Back in the 80s, everything was dental. That was about it. With DNA now, we have so much more that we can do.
TIBBLES: There is also a hotline families of the missing can call. They are being asked to give samples of their DNA to assist in the investigation. For the sister of William Bundy , who heard of the investigation and gave her DNA , the discovery has brought closure.
Ms. O'LEARY: I know that the sorrow will eventually go away and I'll have a place to visit him.
TIBBLES: Ironically, other family members are buried in the same cemetery as Bundy . The family has visited several times over the years, not knowing their brother was just a short distance away. Kevin Tibbles, NBC News, Chicago .
