Christy Luna went missing in 1984 at the age of 8 in Greenacres, Florida. Authorities have now identified a new person of interest in the cold case - Warren Gilbert Williams Jr., a convicted child sex offender who died in 2016. Investigators say they received an anonymous tip that Williams was remodeling a home near the general store where Christy was last seen before her disappearance.
Why it matters
Christy Luna's disappearance has remained unsolved for over 40 years, leaving her family and the community without closure. The identification of a new person of interest, even decades later, offers a potential breakthrough in the long-running investigation and raises hope that her fate may finally be uncovered.
The details
According to the Palm Beach County Sheriff's Office, Christy went missing on May 27, 1984, while going to a general store less than two blocks from her home to buy cat food. Authorities have followed multiple leads over the years and named several persons of interest, but no one has been charged. The new person of interest, Warren Gilbert Williams Jr., was a convicted child sex offender who died in 2016. Investigators say they received an anonymous tip that Williams was remodeling a home near the general store the day Christy went missing and left to buy cigarettes, but never returned. Williams had a history of sexual crimes against children, though there is currently no physical or testimonial evidence linking him to Christy's disappearance.
