A recently opened In-N-Out Burger in Twin Falls became the center of a deadly burst of violence on Saturday, leaving customers and employees caught in a scene that ended with three people dead and seven others wounded.

Police have identified the suspected gunman as 24-year-old Chad Williams.

Investigators believe Williams acted alone before dying from what authorities described as a self-inflicted gunshot wound. He was found dead near the restaurant after allegedly killing an employee and a customer during the attack.

The shooting brought a sudden and devastating end to what should have been an ordinary weekend at the Idaho restaurant. By Sunday, police were working to reconstruct the sequence of events while families, employees and the wider community faced the consequences.

Gunfire Erupts at a Recently Opened Restaurant

The attack occurred on Saturday, Aug. 1, at an In-N-Out Burger location in Twin Falls.

The restaurant had opened only recently, making the violence especially jarring for a business that was still new to the community.

Details about what happened immediately before the shooting remained limited. Authorities had not publicly described a confrontation, disclosed a possible motive or explained why Williams allegedly targeted the restaurant.

What police did make clear was the scale of the damage.

Three people died in the incident, including the suspected shooter. Seven others suffered injuries.

The two victims allegedly killed by Williams included an In-N-Out employee and a customer, police said. Their identities were not immediately released in the initial update.

The condition of those who were wounded was also not detailed.

With so little known about what caused the attack, the absence of a motive left one of the case’s most urgent questions unanswered.

Suspect Found Dead Near the Scene

Police reportedly discovered Williams dead near the restaurant following the shooting.

Authorities later determined that he had suffered a self-inflicted gunshot wound.

The finding meant officers would not have the opportunity to arrest and question him about the attack. Instead, investigators must rely on physical evidence, witness accounts and other available information to determine what led to the violence.

Twin Falls Police Chief Matthew Hicks identified Williams during a Sunday news conference.

Hicks said investigators believed the 24-year-old had acted alone.

That conclusion reduced immediate fears that another gunman might still be at large. However, it did not explain why the restaurant, its employee or its customers became targets.

As the investigation continued, police had not announced any suspected connection between Williams and the victims.

Three Lives Lost

The reported death toll included Williams and the two people he allegedly shot: one employee and one customer.

For the restaurant’s workers, the attack meant losing a colleague inside or near a workplace where they should have been safe.

For the customer’s loved ones, a routine visit to a fast-food restaurant ended in unimaginable loss.

Their names and personal stories had not yet been made public in the early stages of the investigation.

That left the first official account centered largely on numbers: three dead and seven wounded.

Behind those figures, however, were families receiving devastating news, injured survivors facing uncertain recoveries and witnesses attempting to process what they had seen.

The shooting also affected employees who escaped physical injury but were suddenly confronted with violence in a familiar work environment.

Seven People Wounded

City spokesperson Josh Palmer said seven other people were wounded during the incident.

Authorities had not explained whether all seven were struck by gunfire or whether some suffered injuries while attempting to escape the chaos.

Their medical conditions were not immediately disclosed.

The number of people hurt demonstrated how quickly the attack expanded beyond the two fatal victims. A restaurant filled with employees and customers offered little emotional preparation for the sound of gunfire or the urgent need to find safety.

For those present, the shooting likely unfolded in moments.

For investigators, understanding those moments may require a much longer process.

Police will need to determine where Williams entered, how the attack began, what weapon or weapons were involved and whether his movements suggest that specific people were targeted.

Witness testimony may also help establish how the shooting progressed and how the suspect left the immediate restaurant area before being found dead nearby.

Police Believe Williams Acted Alone

The determination that Williams acted alone became one of the most important pieces of information released Sunday.

In the immediate aftermath of a public shooting, authorities must establish whether additional attackers may be involved and whether the danger extends beyond the original scene.

Police Chief Hicks said investigators did not believe that was the case in Twin Falls.

The announcement offered some reassurance to a community shaken by the attack, but many questions remained.

Authorities had not publicly identified a motive. They had not explained whether Williams had any previous relationship with the restaurant, its employee or the customer who was killed.

It also remained unclear how much planning, if any, preceded the shooting.

Without the suspect alive to provide answers, investigators must build that history through evidence left behind.

A Community Confronts Sudden Violence

Twin Falls entered the weekend without warning that one of its newest restaurants would become the site of a deadly shooting.

The violence left a business connected with casual meals and family outings surrounded by police activity and an active investigation.

For residents, the location’s familiarity may make the tragedy especially difficult to absorb.

Public shootings often transform ordinary spaces in an instant. A dining area, parking lot or entrance that once seemed unremarkable becomes permanently associated with fear and loss.

The people inside the In-N-Out Burger on Saturday were not gathered for a major event. They were working, ordering food or spending part of their day at a restaurant.

That everyday setting made the attack no less deadly.

By the time it ended, two victims had been fatally shot, seven people had been wounded and the suspected gunman was dead nearby.

The Investigation Is Still Developing

Police continued investigating the shooting after identifying Williams.

The early findings established several central facts: the suspect was 24 years old, authorities believed he acted alone, and he died from a self-inflicted gunshot wound after allegedly killing an employee and a customer.

Much of the deeper story remained unknown.

Officials had not announced what drove Williams to open fire. The victims had not been publicly identified, and the extent of the survivors’ injuries had not been released.

Those unanswered questions are likely to shape the next stage of the investigation.

Detectives will seek to understand not only what happened inside the restaurant, but what brought Williams there and whether anyone recognized signs of danger beforehand.

For the families affected, those answers may eventually provide context. They cannot undo the violence or restore the lives lost.

The shooting ended with no suspected attacker left to pursue and no indication that another person participated.

But the absence of an ongoing manhunt does not mean the crisis is over.

Seven injured people must recover. Two families must mourn loved ones who entered a restaurant and never returned home. Employees must confront the loss of a colleague and the memory of violence inside their workplace.

And Twin Falls must reckon with how an ordinary Saturday at a newly opened restaurant became the scene of one of the community’s darkest moments.
