In the three weeks since the Louvre museum heist, as investigators sought to find out who was behind it and why the French crown jewels had been so easy to steal, another mystery remained: who the “fedora man” was.

The dapper youth in a hat was photographed outside the museum that Sunday and went viral on social media, prompting theories about his identity.

The first two mysteries were swiftly settled. The thieves’ carelessness with DNA allowed police to work out their identities. The Louvre director admitted CCTV security was inadequate.

However, the fedora man remained an enigma – until now.

The dandy, it turns out, is a local teenage fan of Sherlock Holmes and Hercule Poirot who just happened to be at a real crime scene.

Pedro Elias Garzon Delvaux, a 15-year-old from Rambouillet, south-west of Paris told the Associated Press (AP) news agency that he had planned to visit the Louvre with his family but found the museum was closed.

“We didn’t know there was a heist,” he said.

As he asked officers about the closure, an AP photographer seeking to capture the security cordon took a picture and included Pedro in the frame.

Pedro only realised the photo had gone viral four days later, when a friend sent him a screenshot asking: “Is that you?”

When he replied that it was, the friend said he had five million views on TikTok. “I was a bit surprised,” Pedro told the AP.

He was even more shocked when his mother called to say the picture had appeared in The New York Times. It made a big impact on him, he said, because he reads that newspaper and “it’s not every day you’re in the New York Times”.

“People said, ‘You’ve become a star’. I was astonished that just with one photo you can become viral in a few days.”

Asked why he wore an old-fashioned waistcoat and a fedora to the museum, Pedro said he began dressing this way recently, inspired by 20th-century statesmen and fictional detectives.

“I like to be chic,” he told the AP. “I go to school like this.”

As wild speculation about the photo of him circulated online – some wondered whether he might be a real detective or an AI fake – Pedro remained silent for weeks.

“I didn’t want to say immediately it was me,” he said. “With this photo there is a mystery, so you have to make it last.”

The number of people known to have been killed in a deadly police raid in the Brazilian city of Rio de Janeiro on Tuesday has risen to 132, officials say.

This is more than double the figure cited after the police operation in the favelas (poor neighbourhoods) of Alemão and Penha, in the north of Rio de Janeiro, on Tuesday.

The public defender’s office, which provides legal assistance to the poor, made the new death toll public after grieving residents lay dozens of bodies in a square early on Wednesday.

The police raid was the deadliest in the city, where authorities have for decades tried to contain the gangs which control many of its poorer neighbourhoods.

Asked about the figure given by the public defender’s office, Rio state Governor Cláudio Castro said that forensic work was still under way and that until it had concluded, the official figure which he had been given was of 58 dead, although it was “certain to change”.

Among those expressing shock about the death toll was Brazil’s President, Luiz Inácio Lula da Silva.

According to Brazil’s justice minister, Lula was “astonished” and also expressed his surprise that the federal government had not been informed beforehand.

Even before the number of dead had more than doubled, the United Nations Human Rights office had said it was “horrified” by the police operation.

Early on Wednesday, residents took the bodies of those killed into a square in Penha, where they placed them next to each other in a long line to show the deadly nature of the raid.

According to Brazilian media, estimates varied between at least 50 and more than 70 bodies.

Many of the bodies had reportedly been retrieved from a nearby hillside, where police said most of the deadly clashes had unfolded.

Challenged by journalists about earlier remarks he had made describing those killed as “criminals”, Governor Castro replied: “To be quite honest with you, the conflict wasn’t in a built-up area, it was all in the woods. So I don’t believe anyone was just strolling in the woods on a day of conflict. And that’s why we can easily classify them.”

Residents described the scenes unfolding on Tuesday as “war-like”, with shoot-outs between officers and armed men – with buses set on fire to create barricades.

According to the police, gang members also used drones to drop explosives on the officers as they fanned out through the neighbourhoods, which are strongholds of the Red Command.

“This is how the Rio police are treated by criminals: with bombs dropped by drones. This is the scale of the challenge we face. This is not ordinary crime, but narco-terrorism,” Governor Castro, said.

Governor Castro said that the raid had been two months in the planning and was based on a thorough investigation.

Among those arrested is a man accused of being a leading drug dealer for the Red Command.

The governor also posted photos on social media of the four police officers who were killed in the operation.

He praised the officers killed on what he called “a historic day” in which he said they “confronted organised crime”.

Rafael Soares, a Brazilian journalist covering crime in Rio, told BBC News Brasil that the Red Command had been on the offensive in Rio in recent years, reclaiming territory it had lost to its rivals, First Capital Command (PCC).

Soares added that the police operation was part of Governor Castro’s efforts to leave his mark and deal a decisive blow to crime in the city ahead of elections next year.

The police raid also comes just days before the city is due to host the C40 World Mayors Summit – a meeting of nearly 100 mayors from the world’s leading cities – and the Earthshot Prize – the environmental award which will be handed out by Prince William on 5 November.

A former Illinois sheriff’s deputy has been found guilty of second-degree murder in the death last year of a householder who had reported a suspected intruder.

Mother-of-two Sonya Massey, 36, was fatally shot on 6 July 2024 at her home near Springfield, Illinois, after calling 911 about a possible prowler.

Ex-officer Sean Grayson, 31, said he opened fire because he thought Massey was about to throw a pot of boiling water on him after she said: “I rebuke you in the name of Jesus.”

He was charged with first-degree murder, but the jury was allowed to convict him of the lesser charge of second-degree murder. Grayson faces up to 20 years in prison.

Police bodycam footage of the incident showed the chaotic moments that led to the shooting.

Officers arrived at the home and followed Massey inside when she entered her property, and watched as she searched for her ID.

In the video, Grayson sees a pot sitting on a lit stove, gestures towards it and says: “We don’t need a fire while we’re here.”

Massey walks to the stove to remove the cooking utensil. She and Grayson appear to laugh over her pot of “steaming hot water”, before she twice says: “I rebuke you in the name of Jesus.”

“You better [expletive] not or I swear to God I’ll [expletive] shoot you in your [expletive] face,” Grayson says. He then draws his pistol as he shouts for her to drop the pot.

“OK, I’m sorry,” Massey is heard saying before she ducks.

After shooting her, the officer says: “What else do we do? I’m not taking hot [expletive] boiling water to the [expletive] face.”

The video also captures Grayson telling his police partner that Massey would not need medical help.

As the other deputy tries to get a medical kit, the officer says: “She’s done. You can go get it, but that’s a head shot.”

Sangamon County, where the shooting happened, awarded the Massey family a $10m (£7.6m) settlement in February.
