Is there a link between CTE brain disease and violent crime?

When Noah Green, a 25-year-old with no known history of violence, crashed his car into a barricade at the Capitol building in Washington DC, killing one police officer, before lunging at others with a knife, his own family were grappling for answers.

“My heart just sank,” his mother, Mazie Green, tells me. It was a murder, which, on the face of it, had nothing to do with American football.

But three years on and speaking publicly for the first time since that day, Mazie says she now believes it has everything to do with American football.

Green was shot dead by responding police, and in the days after the killing the FBI recommended that Mazie submit Noah’s brain to be analysed.

The diagnosis came back months later, indicating Green had stage one Chronic Traumatic Encephalopathy, more commonly known as CTE.

It’s a brain disease caused by repetitive blows to the head and it afflicts participants of contact sport, including American football. Symptoms include aggression, paranoia and problems controlling impulses.

“Noah took big hits,” Mazie says. At Alleghany High School in rural Virginia, Green had played in defence and was voted most valuable player and he later played for Christopher Newport University.

Teammates recall him being dependable and good-natured but Mazie says she noticed changes after he suffered several head injuries.

“He wanted to be tough, to prove himself,” Mazie says, “But there were changes. He would start wearing blankets around his head and I thought it was a teenage thing, but it was because he was so sensitive to the light. Then he would lose his keys and he forgot how to cook, prepare his meals.

“After that, he started with these really bad headaches. One day he said ‘I don’t know what’s wrong with me, mum, I’ve lost 20 pounds…. I feel like I need to leave. I’ve got to get out of the country. They’re going to kill me, the FBI, they’re going to kill me.’

“He was paranoid.”

Officer William Evans, the police officer who Noah Green killed, left behind two young children. I ask Mazie if she has any message for his family.

“Officer Evans should not have died that day,” she says, “Noah should not have died that day. Someone has to take the responsibility for telling parents what to do if something’s just not quite right with those kids that are out there playing football for entertainment.”

Shannon Terranova, the former spouse of Officer Evans and mother of his two young children, said: “I want to be mindful of all who are impacted by this real-life horror; but it is difficult for me to comprehend any rationalisation of what happened to Billy and the events that led up to his death. I appreciate the efforts in bringing awareness to the long-term implications of bodily trauma caused by sports injuries. However, nothing can justify what Billy’s co-workers and family experienced, saw, and felt on April 2 2021, and every day since.”

Christopher Newport University declined to comment on Noah Green’s case. Alleghany High School did not respond to Sky News’s request for comment.

The question over whether CTE is linked to violent crime has come to the fore after numerous incidents of violent ex-football players.

Former San Francisco 49ers star Phillip Adams shot dead six people in an explosion of violence in 2021.

He murdered doctor Robert Lesslie, his wife, Barbara Lesslie, and two of their grandchildren, Adah, 9, and Noah, 5 at their home in South Carolina.

He also killed James Lewis and Robert Shook, who were working on an air conditioning unit at the house. Analysis of Adams’ brain showed he had severe CTE.

Kellen Winslow, another former NFL player, was convicted of multiple rapes in 2021.

His lawyer argued for his sentence to be reduced because of what he says was head trauma suffered on the football field. That potential mitigating factor was rejected by a judge.

Most experts say it is hard to say definitively what motivates someone to commit a crime, but the symptoms CTE causes could all contribute. More research into the causes of CTE and what factors might make some people more susceptible is under way.

Sky News was given access to the national sports brain bank in Pittsburgh, Pennsylvania where former professional and amateur American footballers are being urged to donate their brains for study.

Inside the histology laboratory, Dr Julia Kofler slices open a brain with a knife to show me the cross-section.

It is impossible to diagnose CTE with the naked eye so she takes a tiny sample of the brain tissue and loads it onto a slide so it can be analysed under the microscope.

I ask if she thinks there is a link between CTE and violent crime. “It’s really difficult to draw any conclusions about what motivates someone to commit a crime based just on their pathology,” she says, “but we certainly know that neurodegenerative diseases can cause all sorts of different behavioural changes and changes in executive function and judgement, so it certainly could have contributed.”

‘We watched him lose himself’

Karen Kinzle Zegel is one of those fighting for more research. Her son, Patrick Risha, had CTE and died by suicide aged 32. He had played American football throughout his childhood and at university.

“We watched him over 10 years, sadly lose himself, lose his dignity,” she says, “He was paranoid, he was argumentative.

“One time there was an incident with him and he said a homeless guy attacked him in Pittsburgh and he broke his hand punching this person. The rage he had was definitely scary.”

Through her organisation Stop CTE, Karen is campaigning for the brains of those who commit mass violence to be analysed for traumatic injury.

“Every time we’re looking at the symptoms like ‘they lost a job, they, broke up with their girlfriend’.

“Everybody wants to know why, why would someone take another person’s life? But if you’ve dealt with somebody whose brain became unwired you see the lack of empathy. They don’t care about other people, sadly.

“We’re not going back to the root cause, which could be a damaged brain.”

Concerns about brain injuries have contributed to the growth of flag football, a lesser contact sport which means fewer big hits and not an obvious danger.

But the popularity of the NFL as a spectator sport is enduring. Last week’s Super Bowl final was the most-watched TV event in American history.

But for its stars, the damage may already been done. The human cost of the richest sport league in the world is far too difficult to count.

Sky News contacted the NFL for comment about our report. In response, the NFL provided details of the funding they are giving into CTE-related research, mental health support and the physical safety measures they say they are taking in the sport.

Donald Trump praises Liberian president's English - the country's official language

Donald Trump has praised the Liberian president’s command of English – the West African country’s official language.

The US president reacted with visible surprise to Joseph Boakai’s English-speaking skills during a White House meeting with leaders from the region on Wednesday.

After the Liberian president finished his brief remarks, Mr Trump told him he speaks “such good English” and asked: “Where did you learn to speak so beautifully?”

Mr Trump seemed surprised when Mr Boakai laughed and responded he learned in Liberia.

The US president said: “It’s beautiful English.

“I have people at this table who can’t speak nearly as well.”

Mr Boakai did not tell Mr Trump that English is the official language of Liberia.

The country was founded in 1822 with the aim of relocating freed African slaves and freeborn black citizens from the US.

Mr Trump promised the leaders of Liberia, Senegal, Gabon, Mauritania and Guinea-Bissau a pivot from aid to trade at the surprise meeting.

He described the countries as “all very vibrant places with very valuable land, great minerals, and great oil deposits, and wonderful people”.

Later asked by a reporter if he’ll visit the continent, Mr Trump said, “At some point, I would like to go to Africa.”

But he added that he’d “have to see what the schedule looks like”.

Trump’s predecessor, President Joe Biden, promised to go to Africa in 2023, but only fulfilled the commitment by visiting Angola in December 2024, just weeks before he left office.

Gaza permanent ceasefire ‘questionable’, says Israeli government

Gaza permanent ceasefire 'questionable', says Israeli government

The Israeli government believes the chances of achieving a permanent ceasefire in Gaza are “questionable”.

The pessimistic assessment, in a top-level Israeli government briefing given to Sky News, comes as the Israeli Prime Minister prepares to leave Washington DC after a four-day visit which had begun with the expectation of a ceasefire announcement.

Benjamin Netanyahu will leave the US later today with the prospect of even a temporary 60-day ceasefire looking extremely unlikely this week.

Within “a week, two weeks – not a day” is how it was framed in the background briefing late on Wednesday.

Crucially, though, on the chances of the ceasefire lasting beyond 60 days, the framing from the briefing was even less optimistic: “We will begin negotiations on a permanent settlement. But we achieve it? It’s questionable, but Hamas will not be there.”

Sky News has spoken to several Israeli officials at the top level of the government. None will be drawn on any of the details of the negotiations over concerns that public disclosure could jeopardise their chances of success.

But I have been given a very clear understanding of Mr Netanyahu’s thinking.

The Israeli position is that a permanent ceasefire (beyond the initial 60 days, which itself is yet to be agreed) is only possible if Hamas lays down its arms. “If they don’t, we’ll proceed [with the war],” said a source.

The major sticking point in the talks between Hamas and Israel is the status of the Israel Defence Forces (IDF) inside Gaza during the 60-day ceasefire and beyond, should it last longer.

The latest Israeli proposal, passed to Hamas last week, included a map showing the proposed IDF presence inside Gaza during the ceasefire.

This was rejected by Hamas and by Trump’s Middle East envoy, Steve Witkoff, who reportedly told the Israelis that the redeployment map “looks like a Smotrich plan”, a reference to the extreme-right Israeli finance minister, Bezalel Smotrich.

My briefing of Mr Netanyahu’s position is that he has not shifted in terms of Israel’s central stated war aims. The return of the hostages and eliminating Hamas are the key objectives.

But in a hint of how hard it will be to reconcile the differences, it was clear from my briefing that no permanent ceasefire is possible in the Israeli government’s view without the complete removal of Hamas as a political and military entity.

Hamas is not likely to negotiate its way to oblivion.

On the status of the Israeli military inside Gaza, a senior Israeli official told Sky News: “We would want IDF in every square metre of Gaza, and then hand it over to someone.”

It was clear to me that Mr Netanyahu wants his stated position to be that his government has no territorial ambition for Gaza.

One quote to come from my briefing, which I am only able to attribute to a senior Israeli official, says: “[We] don’t want to govern Gaza… don’t want to govern, but the first thing is, you have to defeat Hamas.”

Another clear indication of Mr Netanyahu’s position – a quote from the briefing, attributable only to a senior Israeli official: “You cannot have victory if you don’t clear out all the fighting forces.

“You have to go into every square inch unless you are not serious about victory. I am. We are going to defeat them. Those who do not disarm will die. Those who disarm will have a life.”

On the future of Gaza, it’s clear from my briefings that Mr Netanyahu continues to rule out the possibility of a two-state solution “for the foreseeable future”.

The Israeli government assessment is that the Palestinians are not going to have a state “as long as they cling to that idea of destroying our state”.

On the most controversial aspect of the Gaza conflict – the movement of the population – the briefing revealed that Mr Netanyahu’s view is that 60% of Palestinians would “choose to leave” but that Israel would allow them to return once Hamas had been eliminated.

“It’s not forcible eviction, it’s not permanent eviction,” a senior Israeli official said.

Critics of Israel’s war in Gaza say that any removal of Palestinians from Gaza, even if given the appearance of being “voluntary”, is in fact anything but, because the strip has been so comprehensively flattened.

Reacting to Israeli Defence Minister Katz’s recent statement revealing a plan to move Palestinians into a “humanitarian city” in southern Gaza, and not let them out of that area, the official wouldn’t be drawn, except to say: “As a permanent arrangement? Of course not.”

A senior Israeli official has issued a less-than-optimistic assessment of the permanency of any ceasefire in Gaza.

Speaking in Washington on condition of anonymity, the senior official said that a 60-day ceasefire “might” be possible within “a week, two weeks – not a day”.

But on the chances of the ceasefire lasting beyond 60 days, the official said: “We will begin negotiations on a permanent settlement.

“But we achieve it? It’s questionable, but Hamas will not be there.”

Israeli Prime Minister Benjamin Netanyahu is due to conclude a four-day visit to Washington later today.

There had been hope that a ceasefire could be announced during the trip. US President Donald Trump has repeatedly stated that it’s close.

Speaking at a briefing for a number of reporters, the Israeli official would not be drawn on any of the details of the negotiations over concerns that public disclosure could jeopardise their chances of success.

The major sticking point in the talks between Hamas and Israel is the status of the Israel Defence Forces (IDF) inside Gaza during the 60-day ceasefire and beyond, should it last longer.

The latest Israeli proposal, passed to Hamas last week, included a map showing the proposed IDF presence inside Gaza during the ceasefire.

The official repeated Israel’s central stated war aims of getting the hostages back and eliminating Hamas. But in a hint of how hard it will be to reconcile the differences, the official was clear that no permanent ceasefire would be possible without the complete removal of Hamas.

“We will offer them a permanent ceasefire,” he told Sky News. “If they agree. Fine. It’s over.

“They lay down their arms, and we proceed [with the ceasefire]. If they don’t, we’ll proceed [with the war].”

On the status of the Israeli military inside Gaza, the official said: “We would want IDF in every square meter of Gaza, and then hand it over to someone…”

He added: “[We] don’t want to govern Gaza… don’t want to govern, but the first thing is, you have to defeat Hamas…”

The official said the Israeli government had “no territorial designs for Gaza”.

“But [we] don’t want Hamas there,” he continued. “You have to finish the job… victory over Hamas. You cannot have victory if you don’t clear out all the fighting forces.

“You have to go into every square inch unless you are not serious about victory. I am. We are going to defeat them. Those who do not disarm will die. Those who disarm will have a life.”

On the future of Gaza, the official ruled out the possibility of a two-state solution “for the foreseeable future”.

“They are not going to have a state in the foreseeable future as long as they cling to that idea of destroying our state. It doesn’t make a difference if they are the Palestinian Authority or Hamas, it’s just a difference of tactics.”

On the most controversial aspect of the Gaza conflict – the movement of the population – the official predicted that 60% of Palestinians would “choose to leave”.

But he claimed that Israel would allow them to return once Hamas had been eliminated, adding: “It’s not forcible eviction, it’s not permanent eviction.”
