This year ushered in stories that ignited national conversations surrounding race, bail reform, political power and domestic terrorism – with many headlines quickly going viral online as Americans grappled with tragedy, mystery and often outrage. 

As 2025 comes to a close, take a look at some of the most viral and controversial stories that made headlines and got Americans talking. 

The assassination of Charlie Kirk 

On Sept. 10, conservative activist Charlie Kirk stepped in front of the microphone for the fall kickoff event of Turning Point USA’s "American Comeback Tour" at Utah Valley University in Orem, Utah.

But while speaking in front of over 3,000 students, Kirk was gunned down by a lone assassin positioned on the roof of a nearby campus building approximately 200 feet from the event. Kirk was rushed to the hospital, where he was pronounced dead. 

Video of Kirk’s killing quickly went viral, as countless spectators realized their cameras were rolling as the fatal gunshot was fired – with many capturing the frantic aftermath as students ran for their lives.

Less than two days later, 22-year-old Tyler Robinson walked into a police station in St. George – roughly 265 miles from Orem – to turn himself in as the alleged killer. According to authorities, Robinson was confronted by family members after they noticed he resembled the suspect in photos released by police. 

The case largely continues to play out online, with various angles of Kirk’s assassination captured on social media. Clips of a suspect donned in black on the roof of a campus building just moments before the shooting offered some of the first looks at Kirk’s alleged assassin.

"There’s clearly really no concern about whether anybody was going to see him leaving the scene, as he just jumped off the roof," Peter Valentin, chair of the Forensic Science Department at the University of New Haven and a former Connecticut State Police detective, told Fox News Digital.

"If you take a look at what’s going on at the time of the video being captured, everyone is running from the amphitheater area. So you can imagine people’s ability to take note of things like this is probably somewhat diminished." 

Robinson has been charged with aggravated murder, with prosecutors vowing to seek the death penalty in his case. 

Karen Read acquitted on murder charge

Karen Read’s Massachusetts murder trial captivated the nation, with a jury ultimately finding her not guilty in the 2022 death of her boyfriend, Boston police officer John O’Keefe.

Read was accused of fatally striking O’Keefe with her vehicle, leaving him to freeze to death face-down in the front yard of fellow officer Brian Albert’s home in the early-morning hours of Jan. 29, 2022. 

Prosecutors ultimately charged Read, 45, with second-degree murder, manslaughter while driving under the influence and leaving the scene of an accident causing death. 

For several years, Read maintained her innocence by asserting she dropped O’Keefe off at the home after a night of drinking with friends. 

However, her initial case ended in a mistrial in 2024 after a jury was unable to reach a unanimous verdict.

On June 18, 2025, a jury found Read not guilty of second-degree murder, drunken driving manslaughter and leaving the scene of an accident – clearing her name after three years of legal battles. She was found guilty of the lesser offense of driving under the influence, with a Norfolk County judge sentencing her to a year of probation. 

Despite her acquittal, Read still faces a wrongful death lawsuit brought by O’Keefe’s family, which is expected to play out well into 2026. 

Bourbon Street terror attack rocks New Orleans  

New Orleans’ famous Bourbon Street was marred by tragedy within hours of ringing in the new year, marking the first major mass casualty event of 2025. 

Terrorist Shamsud-Din Jabbar of Texas killed 14 civilians and injured 57 others as he plowed through crowds of New Year’s Eve revelers shortly after midnight on Jan. 1. Jabbar was subsequently killed in a shootout with police.

In the immediate aftermath, the FBI released haunting surveillance images showing Jabbar calmly walking throughout the area within an hour of the horrific attack. 

The images captured Jabbar wearing a light brown coat, dark button-down shirt, blue jeans and dress shoes as he strolled along Dauphine Street near Governor Nicholls Street at 2:03 a.m. CST – about an hour before the attack. 

Additionally, investigators said Jabbar planted a pair of improvised explosive devices inside coolers that he placed in separate areas throughout Bourbon Street. Authorities also uncovered an ISIS flag in the bed of the pickup truck used in the attack. 

According to the FBI, Jabbar, a U.S. citizen, posted five videos to his Facebook account proclaiming his allegiance to ISIS just hours before the attack, while also laying out his plans to carry out mass murder within the famed French Quarter.

Jabbar was "hell-bent on creating the carnage and damage that he did," New Orleans Police Superintendent Anne Kirkpatrick said.

"It was very intentional behavior," she added. "This man was trying to run over as many people as he possibly could."

Bryan Kohberger pleads guilty

In a stunning about-face, Bryan Kohberger, 28, pleaded guilty on July 2 in the brutal 2022 murders of four University of Idaho college students. 

Kohberger, a criminology Ph.D. student at Washington State University, was taken into custody on Dec. 30, 2022, following a monthlong manhunt after Madison Mogen, Kaylee Goncalves, Xana Kernodle and Ethan Chapin were found stabbed to death inside their home in Moscow, Idaho.

In a case that both captivated and horrified the nation, details surrounding the brutality of Kohberger’s crimes quickly spread throughout social media as the Idaho community braced for a headline-grabbing trial, set for the fall of 2025. At the time, authorities alleged Kohberger drove from his apartment in Pullman, Washington, to Moscow, Idaho, in the early morning hours of Nov. 13, 2022, and entered the students’ home through an unlocked door to carry out the murders of Mogen, Goncalves, Kernodle and Chapin as they slept.  

However, in an effort to escape the death penalty, Kohberger pleaded guilty to the murder charges and was sentenced to four consecutive life sentences without the possibility of parole, plus additional time for a burglary charge.

Under the terms of the plea agreement, Kohberger was not required to provide a motive for the killings – a controversial move that led some of the victims’ families to publicly denounce the prosecution’s decision. 

During Kohberger’s sentencing, several family members and friends of the slain students took the stand to offer emotional statements in the presence of their loved ones’ killer – with Goncalves' older sister, Alivea Stevenson, offering fiery remarks to the now-convicted murderer.

"The truth is you're as dumb as they come," Stevenson said as she faced Kohberger. 

"Stupid, clumsy, slow, sloppy, weak, dirty. Let me be very clear. Don't ever try to convince yourself you mattered just because someone finally said your name out loud. I see through you. You want the truth? Here's the one you'll hate the most. If you hadn't attacked them in their sleep in the middle of the night, like a pedophile, Kaylee would have kicked your f---ing a--."

Kohberger remains behind bars in the Idaho Maximum Security Institution in Kuna, Idaho.

The confrontation broke out just after 3 a.m. on July 26 outside the LoVe nightclub, located on the corner of Fourth and Elm Street in the city's downtown business district, with bystander video capturing the moment the group of suspects violently slammed two individuals to the ground. 

In a video obtained by Fox News Digital, an unidentified man can be heard yelling racial slurs while being beaten in the street, with some claiming the male victim slapped the perpetrator prior to the fight breaking out. 

Another angle shows a woman, later identified as "Holly," attempting to break up the fight before she is also slammed to the ground and knocked unconscious.
