Surveillance footage released by Idaho authorities shows the moment a gunman walked up to an In-N-Out Burger drive-thru in Boise and opened fire, killing two people and injuring at least four others before law enforcement shot him dead. The video, published by CBS News, captures what police have described as a random attack that unfolded across multiple locations on a busy Saturday afternoon.
The shooter, identified by the Boise Police Department as 32-year-old Joseph A. Prior, began his rampage at the In-N-Out drive-thru on North Milwaukee Street around 2:30 p.m. on Saturday, June 21, 2025. He had no apparent connection to any of his victims.
Two people are dead and a community is searching for answers in a case that Boise Police Chief Ron Winegar called "prior to anything I've seen in Boise." The attack stretched across at least three locations, lasted roughly 15 minutes, and ended only when officers confronted Prior and fatally shot him.
The footage, captured by In-N-Out's exterior security cameras, shows Pur approaching the drive-thru lane on foot. He walks past vehicles waiting in line, raises a handgun, and fires into at least one car at close range. Customers and employees scramble. The video shows bystanders ducking behind vehicles and running from the parking lot.
Boise police released the video as part of a preliminary briefing on the shooting. Chief Winegar told reporters the footage represents only the opening moments of the attack.
After firing at the In-N-Out, Pur moved to at least two additional locations nearby. Police said he shot at people along West Fairview Avenue and in the parking lot of a neighboring business. The full sequence of locations has not been publicly detailed by investigators.
The two people killed were identified as 51-year-old Mary Stephens of Boise and 24-year-old Hunter Brokaw of Meridian, Idaho. Stephens was shot at the In-N-Out. Brokaw was shot at a separate location along the gunman's path, according to the Ada County Coroner's Office.
Four other victims were transported to area hospitals with gunshot wounds. As of Monday, police said one remained in critical condition. The names of the surviving victims have not been released. Authorities have not confirmed whether any of the injured were In-N-Out employees or exclusively customers and bystanders.
The attack unfolded in a commercial corridor packed with Saturday afternoon traffic. The stretch of North Milwaukee and West Fairview includes several chain restaurants and retail stores, and witnesses described a chaotic scene as people fled on foot and in vehicles. The pattern of violence across the country, including nine separate mass shootings in a single recent weekend, has left communities on edge about random public attacks.
Boise patrol officers reached the scene within minutes of the first 911 calls. Chief Winegar said officers encountered Pur near West Fairview Avenue, where he was still armed. Police ordered him to drop his weapon. When he did not comply, officers fired, striking and killing him.
The Ada County Critical Incident Task Force is handling the officer-involved shooting review, which is standard procedure in Idaho when law enforcement uses deadly force. Winegar said the officers involved have been placed on administrative leave pending the review's outcome.
"This is prior to anything I've seen in my career in Boise. A prior stranger attack of this nature is extraordinarily rare in our community."
Winegar made the statement at a Sunday press conference, flanked by Ada County Sheriff Matt Clifford and Boise Mayor Lauren McLean. McLean called the shooting "a tragedy that strikes at the heart of our sense of safety."
Joseph A. Pur, 32, lived in Boise. Police said he had no prior felony convictions in Idaho. Investigators have not publicly confirmed a motive. Chief Winegar said detectives are examining Pur's digital footprint, interviewing people who knew him, and tracing the firearm used in the attack.
The Bureau of Alcohol, Tobacco, Firearms and Explosives is assisting with the gun trace. Investigators have not said whether the weapon was purchased legally or how long Pur had possessed it. They have also not confirmed whether he had any history of mental health treatment or prior contacts with law enforcement that fell short of arrest.
Questions surrounding how shooters obtain firearms have driven legal battles at every level of the judiciary. A federal court recently heard arguments in what some observers consider the first major lower court test of Justice Thomas's constitutional framework for evaluating federal gun laws.
Hundreds of Boise residents gathered Sunday evening at Julia Davis Park for a candlelight vigil honoring Stephens and Brokaw. Friends described Stephens as a longtime Boise resident and mother of two. Brokaw had recently graduated from Boise State University with a degree in criminal justice, his family said in a statement shared through the Meridian Police Department.
"Hunter wanted to be in law enforcement. He wanted to protect people. The cruelty of how he died is something our family will carry forever."
The statement was released by Brokaw's parents, Jeff and Lisa Brokaw, on Sunday afternoon.
In-N-Out Burger issued a brief statement expressing condolences and confirming the Boise location would remain closed "until further notice." The company said it is cooperating fully with law enforcement. A spokesperson declined to say whether any employees were among the injured, citing the ongoing investigation.
Because the shooter is dead, no criminal prosecution will follow. The primary investigative tracks now are the critical incident review of the officers' use of force and the broader motive investigation led by Boise Police detectives.
Winegar said his department expects to release additional details, including a more complete timeline and information about the firearm, within the coming weeks. He asked anyone with cellphone video or information about Pur's movements before the shooting to contact the Boise Police tip line.
The case has drawn comparisons to other recent mass shootings where accountability questions extended beyond the gunman. In Georgia, a 16-year-old pleaded guilty to all 55 counts in the Apalachee High School massacre, and his father was later sentenced to 15 years for providing the weapon. Whether anyone besides Pur bears responsibility in the Boise shooting remains an open question investigators have not addressed.
Ada County Prosecutor Jan Bennetts said her office is monitoring the investigation but noted there are no pending charges related to the case. Idaho law does not require a grand jury review of officer-involved shootings, though the task force investigation will produce a public report.
Boise, a city of roughly 240,000 that regularly ranks among the safest mid-size cities in the country, has seen very few mass-casualty shootings in its modern history. The Boise Towne Square Mall shooting in October 2021, which killed two and injured four, was the last comparable event. That gunman was later found incompetent to stand trial.
The In-N-Out location opened in 2022 to significant fanfare, drawing long lines for weeks. It sits in one of the busiest retail corridors in the Treasure Valley. Saturday's attack turned a place associated with weekend normalcy into a crime scene visible on national news.
Gun policy debates will inevitably follow, as they do after every high-profile shooting. In Virginia, the NRA recently won a federal injunction blocking that state's ban on semi-automatic firearms and standard magazines, a ruling that underscored the unsettled legal terrain around firearms regulation nationwide.
For now, though, Boise is focused on two people who will not come home and on the survivors still fighting for their lives in hospital beds.
When a gunman can walk up to a drive-thru on a Saturday afternoon and start killing strangers, the questions that matter most are not abstract. They are concrete, local, and urgent, and they demand answers that hold up in court.
