Idaho In-N-Out Shooting: Chad Williams Left Behind a Trail of Social Media Posts — Including One That Now Reads Differently

The investigation into the tragic shooting at an In-N-Out in Idaho has taken a disturbing direction as social media users analyze the online presence of the alleged gunman.

Among the resurfaced posts are two that now bear a haunting new interpretation, although they don’t explicitly explain the reasons behind the violence. On August 1, 2026, a shooter opened fire at the In-N-Out Burger in Twin Falls, resulting in three fatalities and seven injuries, with the chaos spilling into the parking area.

This particular Twin Falls restaurant had only just opened its doors on July 24, serving customers for just over a week before the tragic incident, according to a Facebook post from KMVT News announcing its grand opening.

A Routine Day Turned to Terror

Officials reported that the perpetrator was armed with an AR-style rifle. Footage captured from a nearby vehicle appeared to show him shooting towards a blue Tesla while traversing the parking lot.

Twin Falls Police Chief Matthew Hicks later confirmed that authorities believe the gunman acted independently. He also commended an off-duty state trooper and a civilian who confronted the shooter during the incident.

"We believe their actions helped drive the suspect away from the scene, which likely prevented further casualties," Hicks stated, characterizing the response as highly chaotic.

According to police reports, one employee at In-N-Out even pulled an injured colleague to safety across the parking lot while other workers and bystanders rushed to assist the wounded until paramedics arrived.

Eyewitnesses Describe the Aftermath

Lane Koehn, a witness, recounted to NBC News that he was waiting at a traffic signal outside the restaurant when he spotted a man brandishing an AR-style rifle exiting the drive-thru. He reported that bullets hit the car ahead of him while the gunman moved through the parking area.

"I could see he was trying to decide where to go, and a person in the drive-thru line was firing at him with a handgun," Koehn described.

He noted that the suspect appeared "panicked," looking around and moving in a disorganized manner. Koehn felt that the gunfire exchange provided a critical window for others to escape.

"The shooter was solely focused on him, allowing us to get away," he explained. "The car directly in front of me was being fired upon, which gave them time to leave."

Haley Dodaro, another witness, told the Associated Press that she and her mother initially mistook the frantic scene for a fire as people hurried out of the restaurant.

"That’s when we realized there was a shooting. People were running out, crying and screaming. It was terrifying," she recounted.

Police later confirmed that the shooter was identified as 24-year-old Chad Williams, who died from a self-inflicted gunshot wound following the incident. Authorities have yet to disclose a motive, although Hicks mentioned that Williams’ family has been fully cooperative as detectives continue their investigation into the events leading up to the shooting.

"Their hearts are broken as well," Hicks expressed. Additionally, officials reported that two victims have already been discharged from the hospital, three are in stable condition, while two remain critically injured.

Investigators Explore Williams’ Online Presence

As authorities worked to understand Williams’ background, they began focusing on his online history. Reports indicate that Williams’ biography on X described him as a "former foster care youth" who took part in the Boys State leadership program for high school students in 2019.

Additionally, it was reported that he attended the College of Southern Idaho from August 2022 to December 2023, though he did not complete his degree. During his time there, he was involved in student government, but was impeached by his peers in February 2023 after missing several meetings.

According to previous student government member Elijah Moseley, the impeachment was a "procedural" matter, though he declined to provide details.

Williams’ online activity primarily revolved around political discourse and current events. He consistently weighed in on topics like crime, immigration, and public safety, sharing posts that advocated for stricter immigration control and defended the First and Second Amendments.

Among the content he shared was a post criticizing Manhattan District Attorney Alvin Bragg for reducing felony charges. The post claimed, "Bragg downgraded 60% of felony cases last year, including violent crimes…New Yorkers don’t feel safe in their own city."

He also thanked Florida Representative Anna Paulina Luna for her support of the National Constitutional Carry Act and shared another message asserting, "Free Speech is the bedrock of Democracy and must be protected at all costs."

His Last Post Was Over a Year Prior

While Williams had numerous posts about politics and crime, his last public activity occurred on July 3, 2025, which was more than a year before the shooting.

This final post seemed to be part of a discussion regarding gun laws and firearm registration. Reports suggest that Williams stated, "Many crimes have been solved because of a traceable firearm. Obviously many haven’t."

"This is an argument for the government to register firearms beyond simply ‘it’s only for disarming populations,’ as you asserted. Is it a valid justification to surveil the general population? Not really, and it constitutes another infringement." This marked the conclusion of his online activity, as he did not post again afterward.

An Older Post Gains New Attention

Despite the knowledge of Williams’ last post, another message from months before gained renewed interest. This resurfaced post, dated November 14, 2024, recounted an armed incident near his childhood home in Waddell, Arizona.

In it, he wrote, "Last month a man aimed an AK-47 at the door of a house only streets away from my childhood home. He could have killed you or me simply for stepping outside at the wrong moment over a truck he was trying to sell for just $8,000."

Williams concluded the post by emphasizing, "Waddell, ARIZONA, a border state." Years later, after he was named as the suspect in the Twin Falls shooting, this post re-emerged online, rapidly spreading due to its comments on random violence occurring near his roots.

In-N-Out Expresses Condolences

In the wake of the shooting, In-N-Out’s owner and president, Lynsi Snyder, issued a statement expressing her sorrow over the incident and its repercussions for employees, customers, and their families. The Twin Falls restaurant was the 441st branch of the company.

Snyder confirmed on Instagram that one of the staff members was among the victims of the shooting:

"She was caring for our most valuable asset—our customers—when her life was taken by a despicable individual who does not value the lives of others or his own. He shot both on our property and off, ending his own life shortly after taking the innocent lives of our associate and customers, who never expected this tragedy," Snyder stated.

She pledged that the company would grieve alongside the families of the victims while also supporting employees and customers who witnessed the harrowing event.

Snyder described the loss as heart-wrenching, urging people to seek solace and strength instead of responding with hostility, affirming that In-N-Out would stand united with those impacted and strive to learn from this situation.

Authorities Warn Against Misinformation

As the investigation progressed, police cautioned the public about the dangers of spreading false information online. During a press conference on Sunday, Hicks addressed another name that had been circulating on social media, emphasizing the individual had no connection to the shooting.

"This information is completely incorrect. This person has no involvement in this incident whatsoever," Hicks clarified.

Police noted that an active-duty service member sharing the suspect’s name has been subjected to online harassment and unfounded accusations despite having no ties to the case.

Community Support for Victims

In the meantime, as investigators continue their work, the Twin Falls community has united to support those injured in the attack at the In-N-Out restaurant. North Star Taxi announced that one of its drivers, Terry Dudley, was shot twice in the back while charging his Tesla during the incident.

"Our driver Terry Dudley was a victim of a mass shooting on Saturday," the company stated. "He survived but faces a long recovery ahead."

A GoFundMe campaign created by Dudley’s friend, James Palmer, indicates that the widowed father of four will require multiple surgeries, rehabilitation, and faces mounting medical expenses and lost income during his recovery.

The fundraiser also mentions that any excess funds raised will be shared with other victims and their families.

"Tragedy reveals both the darkest and the most beautiful aspects of humanity. Yesterday, we witnessed unimaginable evil. Today, we have the chance to respond with compassion, generosity, and love," the campaign states.

At the time of publication, the campaign had garnered roughly $21,800 towards its $40,000 target, following 413 contributions.
