(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.”

(PROVO, Utah) — Tyler Robinson, the man accused of killing conservative activist Charlie Kirk, allegedly told his boyfriend, “I had the opportunity to take out Charlie Kirk, and I took it,” according to newly unsealed court documents.
On Sept. 10, 2025, the day of the shooting, Robinson allegedly sent his boyfriend a message that said, “drop what you are doing, look under my keyboard,” according to the search warrant affidavit.
Robinson’s boyfriend told police that he found a handwritten letter under the keyboard, the documents said.
ABC News first reported on the existence of the letter in September.
Police said they reviewed the boyfriend’s photo of the letter. The note read, according to the documents, “If you are reading this per my text, then I am so sorry. I left the house this morning on a mission, and set an auto text.”
“I am likely dead, or facing a lengthy prison sentence,” the letter continued, according to the documents. “I had the opportunity to take out Charlie Kirk, and I took it. I don’t know if I will/have succeeded, but I had hoped to make it home to you. I wish we could have lived in a world where this did not feel necessary.”
Kirk was shot and killed in the middle of his outdoor event at Utah Valley University in Orem, Utah. The 31-year-old was the founder of the conservative youth activist organization Turning Point USA, and the Utah Valley event marked the first stop of his “The American Comeback Tour,” which invited students on college campuses to debate hot-button issues.
Robinson allegedly fled the scene of the shooting, prompting a massive manhunt. He surrendered to authorities on the night of Sept. 11.
He was charged with aggravated murder, felony discharge of a firearm causing serious bodily injury, obstruction of justice, two counts of witness tampering and commission of a violent offense in the presence of a child. He has not entered a plea.

(CHICAGO) — Last October, the Department of Homeland Security claimed that federal agents in Chicago were “forced to deploy their weapons and fire defensive shots at an armed US citizen” after their SUV was “rammed by vehicles and boxed in by 10 cars.”
But analysis of recently released body-camera footage of the shooting of Marimar Martinez and videos verified by nearby businesses and bystanders suggests that those claims were exaggerated — and that federal agents, knowing their actions were being recorded, appeared to coordinate with one another to explain their conduct that day.
Body camera footage and other evidence was released Tuesday after a federal judge last week granted a motion to permit the public release of the materials in the case.
The video shows that in the minute before the shooting, agents were being followed by two, not 10 vehicles. Agents stated they were “boxed in,” but at no time was their vehicle blocked from the front.
At no point in footage from an agent’s body-worn camera or from multiple surveillance cameras is a driver seen ramming the agents’ vehicle; instead, the video shows an agent appearing to steer toward the vehicle driven by Martinez, crashing into her, and then rapidly firing toward her.
Martinez, a U.S. citizen and teacher’s assistant, was shot five times during the incident. She’s now planning to sue DHS and the agent for allegedly making false claims about her following the shooting and labeling her a domestic terrorist.
While prosecutors originally alleged that Martinez “aggressively and erratically” pursued officers that day, a judge dismissed the criminal case against her with prejudice after a reversal by the Department of Justice, which sought to dismiss the case.
A U.S. Customs and Border Protection spokesperson said in a statement that the officer who shot Martinez was placed on administrative leave following the incident. The statement did not indicate the length of the administrative leave or when it began.
“CBP is committed to the highest standards of conduct, transparency, and accountability. All significant use-of-force incidents are thoroughly investigated, reviewed, and presented to the National Use of Force Review Board (NUFRB), an independent body comprised of senior CBP officials and representatives from DHS and DOJ, including the DOJ Civil Rights Division,” the statement said.
Below is a timeline of the incident based on the body camera footage and bystander video leading up to and after the shooting.
The lead-up 10:27:02 a.m.
Three federal agents are riding in an SUV in the first moments of video from an agent’s body-worn camera. Later, the video will reveal an Uber placard on the front of their SUV. One agent is seen speaking into the voice chat app on a nearby phone.
At the time, the Trump administration had surged federal resources for immigration enforcement in Chicago as part of “Operation Midway Blitz.”
According to a court filing, the agents were part of a protective detail assisting a nearby operation in Oaklawn. An FBI agent originally attested that the officers were being followed by multiple civilian vehicles.
10:28:17 a.m.
The agent’s body camera begins recording audio.
“Camera’s on,” the agent says.
The agent readies an assault rifle. With his finger on the trigger, one of the agents can be heard saying what sounds like either “do something, b—-,” or “hit something, b—-.”
10:28:35 a.m.
Another agent is seen pointing his handgun toward the right of the SUV.
A nearby driver repeatedly honks their horn, prompting one of the officers to remark, “Honk all you want.”
The agents’ vehicle is captured on a security camera on Kedzie Avenue. The SUV is flanked by Martinez, in a gray Nissan Rogue, to the agents’ left.
To their right is a GMC SUV, adorned with a Mexican flag on its hood, driven by Anthony Ruiz. Ahead of them are two cars: a sedan and a red pickup truck.
10:28:47 a.m.
Seconds later, the agent with the active body-worn camera says, “Alright, it’s time to get aggressive, get the f—- out. Because they’re trying to box us in.”
“If she hits us, it’s … ,” another agent can be heard saying.
10:28:57 a.m.
Charles Exum, the driver, appears to be the agent who says, “We’re going to make contact, we’re boxed in … we have got to get [inaudible] out of here. “
“We are boxed in,” the agent with the active body-worn camera repeats.
10:28:58 a.m.
The three vehicles briefly enter the frame of a security camera looking over a gas station parking lot.
Martinez, in the Nissan Rogue, is parallel with the agents to their left. Ruiz is behind them and to their right.
The pickup truck and the sedan, previously observed ahead of the agents’ vehicle, are also observed traveling several car lengths ahead of the agents.
10:29:01 a.m.
Exum appears to turn the car’s wheel to the left. A loud crash is heard, and the agents visibly react.
By this time, the two cars ahead of the agents have driven into the path of another security camera. The cars do not stop and drive out of view.
The shooting 10:29:04 a.m.
The agents’ vehicle comes to a stop. Their vehicle and Ruiz’s are seen stopped at the rightmost edge of the gas station security footage. The view of Martinez’s vehicle is blocked, and we do not see the agents’ vehicle make contact with hers.
Exum is seen holding a handgun in his right hand.
10:29:06 a.m.
“Out of the car,” the driver says, as he exits the car with his handgun drawn.
“Be advised, we’ve been struck, we’ve been struck,” the agent with the body-worn camera says.
A second later, five gunshots can be heard in rapid succession.
The agents’ SUV enters the field of view of another security camera. A drawing of the scene — made by one of the agents during their interview with the FBI, according to Martinez’s lawyers — indicated three vehicles were ahead of the agents’ SUV, but the footage shows that at the moment of the shooting, the agents’ vehicle has an unobstructed path forward.
10:29:09 a.m.
Martinez’s vehicle enters the frame of the security camera. She drives north, away from the scene.
10:29:11 a.m.
The agent with the body-worn camera points his rifle toward Ruiz’s vehicle, as it reverses and crashes into a parked car before turning to the left to drive away. Ruiz is later arrested at a gas station a half block away.
“Don’t you f—— move,” the officer says.
10:29:18 a.m.
As the agent turns around, his body camera shows that the SUV is not being blocked in front of it.
The aftermath 10:32:49 a.m.
Exum’s body-worn camera turns on about three minutes after firing his weapon.
10:39:19 a.m.
Exum tells a responding officer that he fired “five to seven shots” at Martinez.
“I don’t know if I hit her or not,” he says. “I [was] angled at the driver, I got five to seven rounds off at her.”
“It was a woman shooting?” the officer asked.
“No, I was shooting,” Exum said.
10:39:38 a.m.
Exum tells a responding officer that he “did the shooting” after Martinez hit his SUV.
“She already hit my vehicle, we got out to defend, she came forward, and that’s when I opened up on her,” he said. “We did not get shot at; we did the shooting.”
10:45:04 a.m.
As more officers arrive at the scene, Exum and the other agents begin to recount the incident and to ask whether his camera was on.
“We were getting out to defend because they already tried to box us in,” he said. “She was moving forward into me.”
“Camera on or no?” an officer said.
“No, I didn’t have it because we were [inaudible],” he said.
“That’s good, as long as you can justify it, bro,” the officer responds.
10:48:14 a.m.
As Exum prepares to light a cigarette, another officer acknowledges that their conversation is being recorded and advises him to “keep everything out.”
“So she hit you guys … You got boxed in?” an officer asked.
“We [were] getting boxed in, and I had to push left. She came in, she pulled over, stopped. I got out so we could defend,” Exum said.
“Hey, hey, just real quick though, since we’re recording, keep it [inaudible],” another officer says. “Keep everything out, you’re good man.”
10:50:30 a.m.
Another officer tells Exum to “keep [his] mouth shut” about the incident.
“Just so you know, you don’t give statements to anybody,” the officer says. “Absolutely no statements at all … You keep your mouth shut.”

(WASHINGTON) — Venezuelan opposition leader Maria Corina Machado said Friday she was “absolutely grateful” to President Donald Trump after meeting with him Thursday and presenting him with her Nobel Peace Prize medal. The president called it a “wonderful gesture of mutual respect.”
“María presented me with her Nobel Peace Prize for the work I have done,” Trump wrote on his social media platform. He also said that Machado was a “wonderful woman who has been through so much” and that it was a great honor to meet her.
Machado, in turn, said Friday it “took a lot of courage” for Trump to take action against Venezuelan dictator Nicolas Maduro.
Following the Thursday meeting, a White House official confirmed to ABC News that Trump did accept the medal.
Further details about the closed-door meeting were not immediately revealed by the White House. Asked about the meeting by ABC News’ Mary Bruce, Trump said it went “great.”
Machado told reporters as she was exiting the White House that she presented Trump with her prize and reflected on the history between the two countries.
“I told him this … Listen to this — 200 years ago, General Lafayette gave Simon Bolivar a medal with George Washington’s face on it. Bolivar, since then, kept that medal for the rest of his life,” she told reporters.
“Actually, when you see his portraits, you can see the medal there. And it was given by General Lafayette as a sign of the brotherhood between the United States, people of United States, and the people of Venezuela in their fight for freedom against tyranny. And 200 years in history, the people of Bolivar are giving back to the heir of Washington, a medal, in this case a medal of a Nobel Peace Prize, and a recognition for his unique commitment with our freedom,” she added.
Simon Bolivar liberated Venezuela and several other Latin American countries from Spanish rule in the 1800s. The Marquis de Lafayette was a French national who volunteered to fight with American colonists during the Revolutionary War and eventually rose to be one of George Washington’s most trusted generals.
Machado didn’t offer any more details about her meeting with Trump.
She won the Nobel Peace Prize last year for her work “promoting democratic rights for the people of Venezuela” and her push to move the country from dictatorship to democracy.
Machado dedicated the prize to Trump, along with the people of Venezuela, shortly after it was announced in October 2025.
She said last week that she would like to give or share the prize with Trump, who oversaw the successful U.S. operation to capture Maduro. Maduro faces drug trafficking charges in New York, to which he has pleaded not guilty.
“I certainly would love to be able to personally tell him that we believe — the Venezuelan people, because this is a prize of the Venezuelan people — certainly want to, to give it to him and share it with him,” Machado told Fox News host Sean Hannity on Monday. “What he has done is historic. It’s a huge step towards a democratic transition.”
The Norwegian Nobel Institute issued a statement last week saying that once the Nobel Peace Prize is announced, it “can neither be revoked, shared, nor transferred to others. Once the announcement has been made, the decision stands for all time.”
When asked earlier this month whether Machado could become the next leader of Venezuela, Trump said it would be “very tough for her” because she “doesn’t have the support or the respect within the country.”
Trump said Wednesday he had a “great conversation” with Venezuela’s acting President Delcy Rodríguez, their first since authoritarian Venezuelan leader Nicolas Maduro was seized by the U.S. on Jan. 3.
“We had a call, a long call. We discussed a lot of things,” Trump said during a bill signing in the Oval Office. “And I think we’re getting along very well with Venezuela.”
The president said last week on his social media platform that he had “cancelled the previously expected second Wave of Attacks” on Venezuela after the government released several political prisoners, but he added that “all ships will stay in place for safety and security purposes.”
Trump has coveted and openly campaigned for winning the Nobel Prize himself since his return to office. White House Director of Communications Steven Cheung slammed the Nobel Committee for its decision after Machado was announced as the most recent winner.
“[Trump] has the heart of a humanitarian, and there will never be anyone like him who can move mountains with the sheer force of his will,” Cheung said in an X post. “The Nobel Committee proved they place politics over peace.”
Jorgen Watne Frydens, the Nobel Committee chair, was asked about Trump’s “campaign” for the prize last year but denied it had any impact on the decision-making process.
“We receive thousands and thousands of letters every year of people wanting to say what, for them, leads to peace,” Frydens said. “This committee sits in a room filled with the portraits of all laureates and that room is filled with both courage and integrity. We base only our decision on the work and the will of Alfred Nobel.”
