(CNN) — Zamil Limon was last seen on the morning of April 16 at his home about three blocks from the University of South Florida campus in Tampa.

Nahida Bristy was last seen later that same morning at the Natural and Environmental Sciences building on campus.

They were both 27 and promising Bangladeshi doctoral students who started out as friends and over time developed feelings for each other — to the point they had thought about marriage, according to Limon’s brother, Zubaer Ahmed.

Limon and Bristy were reported missing by a family friend on April 17, and as days went by, their friends in Florida and relatives abroad became increasingly desperate for answers.

On Friday, Limon was found dead on the Howard Frankland Bridge in Tampa in what Hillsborough County Sheriff Chad Chronister called “a deeply disturbing case that has shaken our community.”

His roommate has been charged with killing Limon and Bristy, whose body has not been found, the sheriff’s office said.

Their loss is being felt far from the Tampa Bay area. Both students had planned to travel to Bangladesh over their summer break.

Investigators called Bristy’s family in Bangladesh to say they believed she may be dead, based on the amount of blood found in Limon and the suspect’s shared apartment, Bristy’s brother told CNN affiliate WTSP. CNN has reached out to her brother and the sheriff’s office for details.

Limon’s family told CNN they were anxiously waiting to learn what happened to the joyful, young researcher.

“It’s devastating for us,” Ahmed told CNN before his brother’s body was found Friday. “We are in deep pain.”

Limon and Bristy were among the more than 17,000 Bangladeshi students — an all-time high — enrolled in US institutions, according to the US Embassy in Bangladesh, citing the 2024 Open Doors Report on International Education Exchange.

“Please keep my beloved brother in your prayers,” Ahmed told CNN Saturday via text message.

Limon was dedicated to his environmental studies

Limon had been working on his thesis for the past two years, studying the uses of generative AI to monitor shrinking wetlands in South Florida, his brother said.

“My brother is very decent and a very simple person,” Ahmed said from Bangladesh. “He always put a smile on his face.”

He had been pursuing a degree in geography, environmental science and policy since the fall of 2024.

After completing his PhD, Limon hoped to return to Bangladesh and get a job as a university professor, Ahmed said.

“I study how natural features evolve across landscapes, with a focus on wetlands, water resources, and vegetation in both agricultural and urban environments,” Limon wrote in his student profile. His goal was “to create practical tools that enhance environmental planning, support sustainable land use, and improve long-term ecosystem management.”

His LinkedIn page said he worked as a graduate student assistant since August 2024, and his experience included stints with the Center for Natural Resource Studies, the Center for Environment and Geographic Information Services and as a junior urban planner in Dhaka. He also studied urban and rural planning at Khulna University, a public research institution in Bangladesh.

Omer Hossain, Limon’s friend and fellow student at USF, remembers him as a “chill guy”

El presidente Donald Trump y la primera dama Melania Trump estaban sentados en el escenario del enorme salón de baile del Washington Hilton poco después de las 8:30 p.m. (hora de Miami) del sábado por la noche, interactuando de manera juguetona con el artista de la velada, el mentalista Oz Pearlman.

Justo afuera, un hombre corrió a través de un punto de control de seguridad con una escopeta en la mano, intercambiando disparos con agentes del Servicio Secreto que lo perseguían, según imágenes de seguridad del incidente que fueron difundidas.

En cuestión de segundos, el hombre armado fue reducido por el Servicio Secreto, antes de que pudiera llegar al salón de baile donde el presidente, funcionarios de la administración Trump, miembros del Congreso y algunos de los reporteros y editores más destacados del país asistían a la Cena anual de la Asociación de Corresponsales de la Casa Blanca.

Dentro del abarrotado salón de baile, los invitados ya estaban sentados y picoteaban ensaladas de burrata y pepino cuando quedó claro que la noche había dado un giro aterrador. Sonidos secos, uno tras otro, provenientes del exterior de las puertas del salón hicieron que el fuerte murmullo de conversación se apagara rápidamente.

Para quienes estaban dentro de la sala —ubicada un nivel por debajo de donde ocurrió el incidente— no era evidente qué eran esos sonidos. Incluso el propio presidente no estuvo seguro de inmediato de lo que había pasado. El primer pensamiento de Trump fue que se trataba de una bandeja llena de platos de la cena que se había estrellado contra el suelo: “He escuchado eso muchas veces”, diría más tarde desde la Casa Blanca, aún con el esmoquin del evento.

Pero cuando agentes de las fuerzas del orden, muchos armados, se desplegaron por la sala desde todas las entradas, quedó claro que había ocurrido un incidente grave. Gritos de “al suelo” se extendieron por el salón mientras los invitados y el personal del hotel se lanzaban debajo de sillas y mesas para cubrirse.

La mesa principal se despejó casi de inmediato. El vicepresidente J. D. Vance fue apartado de la mesa y llevado hacia la izquierda del escenario. Mientras agentes con rifles corrían hacia el frente del escenario, el equipo del Servicio Secreto del presidente lo rodeó, según un video grabado desde un costado del escenario. Mientras era evacuado, el presidente pareció caer brevemente al suelo antes de que él y la primera dama fueran llevados rápidamente a una sala segura del hotel. Quienes estaban sentados a su lado fueron trasladados a una sala distinta al final del pasillo.

Los asistentes a la cena que eligieron ese momento para salir del salón de baile antes de que se sirviera el plato principal, incluido Wolf Blitzer de CNN, lamentablemente se pusieron en peligro. Blitzer acababa de salir de un baño fuera del salón cuando vio al hombre armado a solo unos pocos pies de distancia.

“Empecé a escuchar disparos en el pasillo, justo cerca de mí, y lo siguiente que supe fue que un agente de policía me tiró al suelo y se puso encima de mí”, dijo Blitzer. “Los disparos fueron tan fuertes, tan aterradores, que nos asustó a todos. No teníamos idea de qué estaba pasando”.

El presentador de CNN fue llevado de vuelta al baño de hombres, donde él y más de una decena de personas se refugiaron en el lugar, dijo.

Perdió un zapato en medio del alboroto.

Cuando el hombre armado arremetió contra el punto de control, llevaba una escopeta, una pistola y varios cuchillos, según funcionarios de las fuerzas del orden. Un agente del Servicio Secreto recibió un disparo en el pecho durante el intercambio de disparos y estaba bien después de ser trasladado a un hospital gracia

(CNN) — The soaring cost of jet fuel due to the war in Iran will lead to significantly higher airfares. But don’t expect ticket prices to drop once fuel prices start to decline.

Higher fares are being driven by strong demand for travel as much as the cost of fuel. Despite higher ticket prices, travelers are booking tickets in record numbers at many airlines. So, as long as passengers keep flying, higher fares are likely to stay in place, no matter the cost of fuel.

“The longer consumers pay these prices and airlines get used to this revenue stream, the more likely it is (to hold),” United CEO Scott Kirby said during its earnings call Wednesday. The airline’s passengers are now paying on average 20% more for every mile they fly compared to last year.

When asked about keeping higher fares when fuel prices normalize, American Airlines CEO Robert Isom said customers have already been willing to pay more for things like extra legroom or seats closer to the front.

“I’m bullish on what that means for our business,” Isom told analysts Thursday.

He said that summer bookings have stayed strong even as the airline raised fares.

“I think that what you’re seeing is recognition that travel is still a good deal,” Isom said.

The price of jet fuel, which has roughly doubled since the start of the year, is a major factor behind the widespread fare increases. Fuel is the second largest operating cost for airlines behind only labor.

The nation’s four largest carriers — United, American, Delta and Southwest — spent on average a combined $100 million a day on fuel last year. And that was during a time of relatively cheap oil and fuel costs.

Today, they’re paying billions more. Delta said it faced $2 billion in increased fuel costs in the current quarter alone.

Airlines are passing some of the cost to consumers. Recent results show they’re already charging passengers 20% more for every mile they fly compared to a year ago, and fares are projected to go higher still.

Southwest Airlines Chief Operating Officer Andrew Watterson told investors Thursday there have already been five industrywide fare hikes so far this year, with more on the way. And all the airlines say they’ve only recovered a portion of their increased costs.

Fares about far more than costs

But fares are not based on the cost of operating a flight, said Zach Griff, author of an airline newsletter, From the Tray Table.

Instead, price is primarily determined by demand — for a certain route, time of day or week and the amount of competition.

For example, midweek or overnight redeye flights are typically cheaper than prime travel times on the same route, such as on Friday afternoon. And passengers often pay far less for every mile traveled on popular long-haul flights between major cities, such as New York and Los Angeles, than on shorter routes with less demand.

Airlines are cutting some of these less profitable flights, which have become money losers amid higher fuel prices. United, for example, has cut its previously planned schedule by about 5% through September. Removing these bargain fares is also lifting the average ticket price.

But with travelers still booking tickets, airlines know they can make higher fares stick on their remaining flights.

“The fare environment will ultimately play out based on market conditions,” Southwest’s Watterson said.

There is also the possibility that Spirit Airlines, a trendsetter in ultra-low fares, could fold under the weight of higher fuel costs.

The budget carrier, which has filed for bankruptcy twice in the last two years, warned in March it could go out of business. The Trump administration has said it’s looking at possibly bailing it out or even buyi

(CNN) — President Donald Trump and first lady Melania Trump were seated on the stage of the cavernous Washington Hilton ballroom just after 8:30 p.m. ET Saturday evening, playfully engaging with the evening’s entertainer, mentalist Oz Pearlman.

Just outside, a man sprinted through a security checkpoint with a shotgun in hand, exchanging fire with Secret Service agents who chased behind him, according to security footage released of the incident.

Within seconds, the gunman was subdued by Secret Service — before he could reach the ballroom where the president, Trump administration officials, members of Congress and some of the nation’s most prominent reporters and editors were all in attendance for the annual White House Correspondents’ Association Dinner.

Inside the jammed ballroom, guests had taken their seats and were picking away at burrata and cucumber salads when it became clear the evening had taken a frightening turn. Cracking sounds in quick succession from outside the ballroom doors caused the loud hum of conversation to quickly turn silent.

It wasn’t obvious to those inside the room — situated a level below where the incident occurred — what the sounds were. Even the president himself wasn’t immediately sure what had happened. Trump’s first thought was a tray full of dinner plates crashing to the floor: “I’ve heard that many times,” he would say later from the White House, still wearing his tuxedo from the event.

But as law enforcement agents, many armed, fanned into the room from all the entrances, it became obvious a serious incident had occurred. Shouts of “get down” swept across the ballroom as guests and hotel servers dived underneath chairs and tables to take cover.

The head table was cleared almost immediately. Vice President JD Vance was pulled back from the table and taken off to the left of the stage. As agents with rifles ran to the front of the stage, the president’s Secret Service detail surrounded him, according to video from the side of the stage. As he was being evacuated, the president appeared to briefly fall to the floor before he and the first lady were whisked to a secure room in the hotel. Those sitting alongside him were taken to a separate room down the hall.

‘It scared all of us’

Dinner attendees who had chosen that moment to leave the ballroom before the main course was served, including CNN’s Wolf Blitzer, had unfortunately put themselves in harm’s way. Blitzer had just left a restroom outside the ballroom when he saw the gunman just feet away from him.

“I start hearing gunshots in the hall right near me, and the next thing I knew, a police officer threw me to the ground and was on top of me,” Blitzer said. “The gunshots were so loud, so frightening that it scared all of us. We had no idea what was going on.”

The CNN anchor was taken back into the men’s restroom, where he and more than a dozen others sheltered in place, he said.

He lost a shoe in the commotion.

As the gunman charged the checkpoint, he was armed with a shotgun, a handgun and multiple knives, according to law enforcement officials. A Secret Service agent was shot in the chest during the exchange of gunfire and was OK after being taken to a hospital thanks to the bulletproof vest he was wearing, Trump later told reporters.

The suspected gunman was identified by law enforcement officials as Cole Tomas Allen, a 31-year-old from a Los Angeles suburb who

(CNN) — The hashtag ‘alpine divorce’ has exploded on social media platforms like TikTok and Instagram in recent months, with many women sharing traumatic, sometimes life-threatening experiences.

The term is used to describe an event during a hike or other outdoor adventure, when one partner, usually male, abandons the other, who is typically less experienced and more vulnerable, in a remote and potentially dangerous setting.

Conversation has in part been driven by a high-profile case in Austria earlier this year, which saw a climber convicted of manslaughter and handed a suspended sentence after he left his girlfriend alone on Grossglockner mountain, the country’s tallest, as he claimed he went to seek help. She froze to death.

Prosecutors accused the man, named as Thomas P., of not answering calls from rescue services despite having phone signal and failing to send distress signals in time. During his trial, an ex-girlfriend testified that he had abandoned her on the same mountain in 2023 because he considered her too slow, Germany’s Bild newspaper reported. He tended to get “grumpy” if she was struggling during a hike, she told the court during her testimony.

Amid the trial, women were sharing their personal stories online. “POV: you go on a hike with him in the mountains but he leaves you alone by yourself and you realise he never liked you to begin with,” one woman wrote in a clip on TikTok which shows her alone on an isolated mountain path and has amassed nearly 5 million views.

In a post on X, another woman shared a video of walking in wilderness by herself, writing, “This is a video of me hiking in the Scottish Highlands trying to make the best out of my trip while the guy I was in a situationship with was miles ahead of me.” The clip has 1.9 million views.

Coined in an 1893 short story by Scottish Canadian writer Robert Barr about a husband plotting to kill his wife in the Swiss Alps, ‘alpine divorce’ is not a legally or officially recognized term. However, behavioral psychologist and relationship coach Jo Hemmings told CNN the relationship dynamics behind it were identifiable.

According to Hemmings, perpetrators are commonly those with an avoidant attachment style, who emotionally and physically distance themselves from others when under stress rather than addressing the cause.

“They are likely to lack empathy and compassion and avoid conflict – preferring to remove themselves,” she said. “I see this kind of behavior frequently in my counselling rooms – a partner, most often a man with a female partner, who withdraws under questioning, or may even leave the room or give up on the counselling altogether.”

While ‘alpine divorce’ may not be a common experience, Hemmings believes the underlying concept will be familiar to many women. “Not because of the mountainous setting, but because emotional withdrawal or even abandonment within a relationship is relatively common.”

A mountainous setting adds another dimension to this pattern of behavior, however, rendering it potentially dangerous. Such outdoor activities create an instant hierarchy; who leads, who navigates and who sets the pace.

“Walking ahead and refusing to adapt can be a subtle way of asserting authority or control,” Hemmings said.

‘I needed to get help’

Although most often describing romantic partners, the term can apply where typically women are deserted by other male figures they thought they could trust, such as fathers, brothers, other family members and friends.

Keen hiker Laurie Singer, from California, felt betrayed by a long-term male friend when she became ill on a weeks-long hike in a situation which left her fearing for her life.

In 2016, at the age of 56, Singer said she set out on the Read more
