(PALM BEACH COUNTY, Fla.) — Christy Luna disappeared without a trace over 40 years ago at the age of 8. Now, authorities in Florida say they have identified a new person of interest in the cold case.

Christy went missing on May 27, 1984, while going to a general store less than two blocks from her home in Greenacres to buy cat food, according to the Palm Beach County Sheriff’s Office. No one knows what happened to her after she bought the food for her two cats, and a massive search at the time didn’t turn up anything. 

The sheriff’s office has followed multiple leads over the decades since and has named several persons of interest in the case, but no one has been charged in connection with her disappearance.

On Wednesday, authorities announced they are looking for information on a new person of interest — Warren Gilbert Williams Jr., a convicted child sex offender who died in 2016.

Sgt. Chris Karpinski, with the Palm Beach County Sheriff’s Office’s cold case unit, said they received an anonymous tip last year that Williams was remodeling a home near the general store the day Christy went missing.

“He left that home and his remodeling efforts to go buy cigarettes at Belks General Store and he never returned,” Karpinski said during a press briefing on Wednesday.

“That alone, interesting information, but we have a lot of that information through the years where somebody was seen in the area, and this and that,” he continued. 

But Williams, he said, has a “peculiar past of sexual activity with children.” He was convicted of sexual battery on a child under 12 and lewd and lascivious molestation and was imprisoned in Florida from 2007 to 2013, according to Karpinski. After finishing that sentence, he went to prison in Alabama, where he was wanted for sexual abuse of a child, Karpinski said.

“The suspicion existed through this circle of people that Mr. Williams knew through the years, and they had discussed the possibility of him being involved with Christy’s disappearance,” Karpinski said.

Detectives also learned through the anonymous tip that Williams, who lived in what is now known as Lake Worth Beach at the time, installed a concrete pad in his backyard a week after Christy went missing.

Authorities got permission from the current homeowners to search the property and last month excavated the yard, Karpinski said.

“Unfortunately, we found nothing,” Karpinski said, saying there were “mixed emotions” on the development.

“We wanted to find something, but yet, finding something meant that, you know, we had bad news, at least it was for me,” he said. “So there is still hope that Christy either is out there or somebody is out there that knows where she is, whether she is still with us on Earth or has passed.”

Karpinski said there currently is no physical or testimonial evidence that links Williams to Christy’s disappearance.

“We want to learn more about him,” Karpinski said. “I know it’s a long time ago. People, friends, neighbors, witnesses that day who think maybe they saw him, please come forward.”

Williams, who was 46 years old at the time Christy disappeared, died in prison in 2016, according to Karpinski.

Authorities haven’t ruled out any other persons of interest named in the case, according to investigator Bill Springer, who has been investigating Christy’s disappearance since the sheriff’s office assumed the case in 1984.

Springer also urged anyone with information to come forward, even after all this time.

“I want people to come forward. I’m not going to question why you didn’t come forward, because I don’t care,” he said. “My job is to find Christy, not to judge people because they didn’t come forward.”

“So if you’ve got information and you’ve been sitting on it for 30 years, 40 years, I don’t care,” he said. “Bring it out and we’ll look at it, see what we can do with it.”
