On May 26, 2021, a mass shooting took place at the Santa Clara Valley Transportation Authority (VTA) rail yard located in San Jose, California. Samuel James Cassidy, a 57-year-old employee of the VTA, fatally shot nine of his coworkers before turning the gun on himself. This tragic event marks the deadliest mass shooting ever recorded in the San Francisco Bay Area.

The attack led to an extended suspension and reduced operations throughout the VTA light rail network. In reaction, local authorities enacted new policies aimed at curbing gun violence, including pioneering legislation mandating liability insurance for gun owners and imposing fees on firearm possession.

Background

The VTA manages both bus and light rail transit services within Santa Clara County, employing approximately 2,000 individuals. The shooting unfolded at the Guadalupe Division facility situated in San Jose’s Civic Center district, adjacent to the headquarters of the Santa Clara County Sheriff’s Office and San Jose Police Department. This complex comprises five buildings that contain the control center as well as storage and maintenance areas for light rail vehicles. A workforce of 379 VTA employees was stationed at this site.

California enforces some of the most stringent gun regulations in the United States, including a red flag law that permits authorities to confiscate firearms based on court-issued restraining orders. In 2019 alone, Santa Clara County sought 122 such orders.

Shooting and house arson

On the morning of the incident, at 5:39 a.m. PDT (UTC−07), the shooter departed his residence after setting it ablaze. The home was unoccupied at that time. Investigators reported that he started the fire by placing ammunition inside a pot on his stove surrounded by flammable materials.

At 6:33 a.m., the San Jose Fire Department received a report concerning the VTA site; initial communications did not indicate an active shooter situation. One minute later, emergency responders were alerted to gunfire through multiple 9-1-1 calls. Deputies from the sheriff’s office and city police officers arrived swiftly from nearby headquarters. They reached the location by 6:35 a.m., discovering several individuals had been shot.

The attack took place across two buildings during a shift transition when more than 100 employees were present. It started inside a conference room in Building B amid a meeting involving a power crew and the local Amalgamated Transit Union president, who was not harmed. The assailant then proceeded to Building A and continued shooting. According to police reports and eyewitness accounts, he selectively targeted certain individuals while sparing others.

At 6:36 a.m., a passerby alerted authorities to the house fire in South San Jose, located approximately from the VTA facility. Firefighters discovered large quantities of ammunition and a gas can at the scene; significant damage was inflicted on the residence with partial collapse of its second floor.

Meanwhile, confirmation of an active shooter at the transit facility was received by fire officials. At 6:38 a.m., officers heard additional gunshots. Roughly ten minutes following initial emergency calls, all shooting ceased. By 6:43 a.m., law enforcement confronted Cassidy on the third floor of Building A near administrative sections and operations control; he had taken his own life by shooting himself twice. The sheriff’s office later verified that Cassidy died from self-inflicted gunshot wounds.

Immediate aftermath

At 7:12 a.m., authorities from the sheriff's office urged the public to steer clear of the facility. By 8:08 a.m., officials confirmed that the shooter had been neutralized after discharging 39 rounds from three semiautomatic pistols and carrying 32 high-capacity magazines, each holding between 12 and 15 rounds. Law enforcement successfully evacuated approximately 40 individuals. Due to reports indicating potential explosive devices, a bomb squad was dispatched for investigation; a locker registered to the shooter contained suspected bomb components, which were later determined to pose no threat. The FBI and ATF agents responded promptly, with the FBI assuming leadership of the investigation that concluded on May 31.

Sheriff’s deputies conducted a thorough three-day search of the shooter’s residence, uncovering a cache that included 12 firearms, 25,000 rounds of ammunition, and twelve Molotov cocktails. Bomb disposal experts safely detonated a suspicious device found on site, which was ultimately found to be inert.

Victims

The attack claimed the lives of ten male VTA employees ranging in age from 29 to 63 years, many of whom had long tenures with the agency. Among those killed were Paul Delacruz Megia, Taptejdeep Singh, Adrian Balleza, Jose Dejesus Hernandez, Timothy Michael Romo, Michael Joseph Rudometkin, Abdolvahab Alaghmandan, Lars Kepler Lane, and Alex Ward Fritch. Eight victims died at the scene while two others sustained critical injuries and later succumbed at Santa Clara Valley Medical Center. Six fatalities occurred in Building B and three in Building A. Several victims reportedly assisted colleagues in escaping prior to their deaths.

Autopsy results confirmed that all nine victims died due to multiple gunshot wounds. This tragedy marked the deadliest mass shooting in Bay Area history, surpassing the nine fatalities of the 1993 101 California Street incident. It is also recognized as one of the most lethal mass killings targeting men in the United States during the 21st century.

In August 2021, a railyard worker who witnessed the shooting died by suicide on his first day returning to work after the event.

Perpetrator

Law enforcement identified the shooter as 57-year-old VTA employee Samuel James Cassidy (August 29, 1963 – May 26, 2021), a resident of Cupertino, California. Cassidy had been employed by VTA since 2001, initially serving as an electro-mechanic before being promoted to substation maintainer in 2014.

Cassidy legally owned several registered firearms including shotguns and long rifles. The three semiautomatic handguns he used during the attack were all legally acquired. However, it remained unclear whether he legally possessed the high-capacity magazines utilized; such magazines are restricted in California unless obtained prior to 2000. His criminal history was minimal, including a misdemeanor obstruction charge from 1983.

Possible motives

According to Cassidy’s ex-wife, he struggled with anger issues and harbored resentment toward coworkers and VTA management over what he perceived as unfair work assignments. She revealed that he had mentioned plans to kill people at his workplace more than ten years earlier.

An initial review by VTA uncovered a pattern of insubordination and verbal conflicts involving Cassidy on at least four occasions with colleagues. Despite reports leading to some managerial awareness and disciplinary considerations, he was never formally reprimanded and was even commended by certain supervisors. Coworkers noted Cassidy’s dissatisfaction with a policy eliminating cash payouts for unused vacation days and recalled complaints he made over the light rail operators’ radio system in April 2021. Cassidy’s sister believed that an incident at work on May 25 may have influenced his actions on the following day.

Detainment in 2016

A memorandum issued by the United States Department of Homeland Security (DHS) in August 2016 outlined the circumstances under which Cassidy was held by U.S. Customs and Border Protection (CBP) following his return from the Philippines for secondary screening. During this process, officers discovered books related to terrorism and a notebook containing notes that expressed animosity toward the VTA. Cassidy refuted any claims of workplace disputes. Although DHS officials identified potential concerns linked to sex tourism, no evidence substantiated these suspicions, resulting in no arrest or further investigation.

A CBP document made public in July 2021 indicated that Cassidy harbored "dark thoughts about harming" two individuals; however, their association with the VTA or shooting victims remains uncertain. During interrogation, CBP agents concentrated on sex tourism issues, referencing mentions of "sex friendly" hotels in his writings and communications with women in the Philippines.

San Jose authorities reported they were not notified by federal agencies about Cassidy’s detainment. Former acting ICE director John Sandweg explained that there is no established procedure requiring customs officials to inform local law enforcement when detained U.S. citizens pose potential safety risks. Santa Clara County district attorney Jeffrey F. Rosen stated that, had his office been informed, it could have pursued a gun violence restraining order to confiscate Cassidy’s firearms.

Memorials and Support for Victims

A dedicated hotline was set up to provide information to VTA employees and families affected by the shooting incident. The VTA committed to offering assistance to survivors and relatives while collaborating on establishing a public memorial. Some staff members voiced criticism regarding the VTA’s response, attributing most support initiatives to the local chapter of the Amalgamated Transit Union.

San Jose Mayor Sam Liccardo described the event as a "horrific day" for both the city and VTA, extending sympathies and emphasizing the importance of VTA workers as essential personnel amid the COVID-19 pandemic in California. President Joe Biden and Vice President Kamala Harris called on Congress to advance gun control legislation; Biden also ordered flags to be flown at half-staff and labeled the shooting a "horrific tragedy." Governor Gavin Newsom echoed these sentiments during his visit to San Jose.

The following day, hundreds gathered at a vigil outside San Jose City Hall, including family members of victims and VTA employees wearing uniforms. On June 22, the San Jose City Council intended to pass a resolution honoring those who lost their lives.

On June 28, the California State Legislature approved a $20 million allocation within the state budget aimed at supporting VTA’s recovery initiatives. These funds are earmarked for mental health services for employees and their families, restoration of light rail operations, and safety enhancements at Guadalupe Rail Yard.

VTA service disruptions and restoration efforts

On the day of the shooting, VTA light rail operations were halted and substituted with a bus bridge. Due to limited personnel and the impacted facility being inaccessible, this bus bridge service concluded on June 1, leaving the light rail system suspended with no set date for resumption. In a show of solidarity, several transit agencies—including San Francisco Municipal Railway, Golden Gate Transit, SamTrans, AC Transit, and Santa Cruz Metropolitan Transit District—contributed between 20 and 30 buses daily to augment transit options while VTA staff participated in funeral services.

Passenger service gradually restarted during August and September. Beginning August 2, a complimentary bus bridge operated along segments of the Blue and Orange lines, connecting Paseo de San Antonio with Milpitas. By August 29, light rail service was restored on the Orange Line as well as portions of the Green Line. Further expansion into downtown San Jose occurred on September 2. The Blue Line resumed full operations on September 12, followed by the reopening of the Green Line south of downtown on September 18.

The incident inflicted extensive damage on light rail operational and control systems. Consequently, bus operations were relocated to a provisional facility while VTA undertook efforts to reinstate light rail service, including retraining operators and reacquainting drivers with the Guadalupe yard. The agency remains undecided on whether to renovate or reconstruct the impaired structures and anticipates functioning from temporary sites for three to five years.

Investigations and judicial actions

As of December 2021, investigations into the shooting are being conducted by the Santa Clara County Sheriff's Office alongside an external law firm engaged by VTA. A probate matter concerning Cassidy’s estate, which involves his residence fire, remains active. Additionally, families representing at least seven victims have expressed intentions to initiate legal action in 2022.

Revisions to San Jose’s firearm regulations

On June 8, 2021, Mayor Liccardo together with four city councilmembers introduced ten harm reduction strategies aimed at reducing gun violence. These included two groundbreaking proposals: compulsory liability insurance for gun owners and an annual fee designed to offset municipal emergency response expenses related to firearms incidents. A gun buyback initiative was also among the suggestions. Some of these policies had been initially proposed following the 2019 Gilroy Garlic Festival shooting but were postponed due to the COVID-19 crisis. The proposals for liability insurance and fees encountered opposition citing California’s preemption laws that restrict local governance in this domain.

On June 15, the City Council unanimously adopted an ordinance mandating that gun retailers capture video and audio recordings during firearm sales to deter straw purchases. By June 29, all ten ordinances were submitted for legal evaluation with intentions to revisit council approval in September. On January 25, 2022, the City Council enacted the Gun Harm Reduction Ordinance—the nation’s first law imposing both a gun fee and a liability insurance requirement—prompting immediate litigation from the National Association for Gun Rights (NAGR).

District Judge Beth Labson Freeman partially dismissed NAGR’s lawsuit in September 2022 but allowed amendments; a subsequent dismissal occurred in July 2023 under similar terms. These decisions represented important judicial milestones in San Jose’s pursuit of enforcing novel gun control initiatives.

As of September 2021, no timeline had been established for implementing the proposed gun buyback program.

Policy initiatives

San Jose city leaders encouraged other municipalities across California to participate in an amicus brief backing the state's appeal in Miller v. Bonta, a case that invalidated the 1989 assault weapons prohibition shortly after the June 4 incident. While Cassidy did not employ an assault weapon during the attack, Attorney General Rob Bonta referenced the San Jose event to argue against the court’s decision. Congresswoman Zoe Lofgren highlighted the importance of enacting the Enhanced Background Checks Act and the Bipartisan Background Checks Act, although both legislative efforts currently face a filibuster in the Senate.

Investigations disclosed that local law enforcement was not notified by the Department of Homeland Security regarding Cassidy’s detention in 2016. The department acknowledged ongoing enhancements to its information-sharing protocols, aiming to rectify shortcomings that have impacted responses to incidents such as the 2021 United States Capitol attack and the Stoneman Douglas High School shooting. On July 12, Mayor Liccardo held discussions with President Biden focusing on approaches to reduce gun violence nationwide.

In response to increased anti-Asian hostility following the shooting, a petition called on officials to address safety concerns raised by San Jose Public Library staff, who pointed out deficiencies in security measures and protocols.
