He was described by coworkers as a quiet and reserved person who kept to himself, but had a history of disputes with his coworkers and had been the subject of a workplace violence investigation in 2016. The investigation found that Cassidy had made threatening comments to his coworkers, but he was not terminated from his job and was allowed to continue working at the rail yard.
At 6:30 a.m. on May 26, 2021, Samuel Cassidy, a 57-year-old maintenance worker at the Santa Clara Valley Transportation Authority (VTA), opened fire inside the light-rail yard break room in San Jose, California, killing nine coworkers and wounding no others before turning the gun on himself. The victims ranged in age from 29 to 63, including transit supervisors, electricians, and equipment operators who had gathered for the morning shift. This attack became the deadliest mass shooting in Northern California in over a decade and the 232nd mass shooting recorded in the U.S. that year by the Gun Violence Archive. Cassidy used a 9mm Smith & Wesson handgun legally purchased in 2016, along with a second firearm found at the scene.
The shooting shut down VTA light-rail operations across Santa Clara County, affecting tens of thousands of commuters. First responders recovered 10 bodies, including Cassidy’s, and secured more than a dozen firearms from his home in San Jose during a follow-up search. A 240-page police report later revealed Cassidy had expressed grievances about work conditions and money in handwritten notes found at his home and at the scene. Despite no prior criminal record, coworkers had reported his erratic behavior over the years, including complaints about surveillance and perceived workplace injustices. The attack reignited debates over workplace threat assessment protocols and California’s gun control laws, particularly around red-flag mechanisms and employer reporting responsibilities.

Within hours of the shooting, San Jose Mayor Sam Liccardo declared a state of emergency, and the VTA suspended all light-rail service for three days. On May 29, more than 1,200 people gathered at City Hall for a candlelight vigil, where the names and photos of the nine victims were projected onto the building. The VTA established a $1.5 million relief fund for victims’ families, and the State of California approved $5 million in victim compensation through the California Victim Compensation Board. Counseling services were made available to over 300 VTA employees, many of whom had responded to the scene or discovered the aftermath firsthand.
By August 2021, the VTA adopted a new workplace violence prevention plan developed with the FBI and San Jose Police, including panic alarms, bullet-resistant glass in control rooms, and mandatory active shooter training. Metal detectors were installed at all major transit facilities by early 2022. In 2023, a civil lawsuit filed by victims’ families alleged the VTA ignored warning signs, including Cassidy’s 2020 complaint that coworkers were poisoning his food. The agency settled the suit for $4.5 million without admitting fault. The FBI continues to use the case in training modules on insider threat recognition in critical infrastructure, citing the 240-page San Jose Police Department investigative report as a key case study.
The Questions the Disaster Left Behind
The nine victims—Paul Delacruz Megia, 42; Taptejdeep Singh, 36; Alexander Crow, 29; Jose Dejesus Hernandez III, 35; Lars Kepler Lane, 63; Timothy Michael Romo, 49; Michael Joseph Rudometkin, 40; Abdolvahab Alaghmandan, 69; and Chris Marquez, 35—were memorialized in a permanent garden at the VTA’s Eastridge facility. Their deaths prompted OSHA to issue new guidelines for transit agencies on identifying behavioral threats among employees. In 2022, California strengthened its gun violence restraining order law, allowing coworkers to petition for firearm removal—a change directly influenced by Cassidy’s history of workplace grievances.
The VTA shooting exposed gaps in how public agencies handle internal threats, even when warning signs exist. While Cassidy had no criminal record, he had accumulated firearms, stockpiled ammunition, and written about revenge in personal journals. The attack did not prompt federal legislation, but it led to concrete changes at the state and agency level, including a statewide push for behavioral threat assessment teams in public transit. The tragedy remains a case study in how workplace culture, mental health, and access to firearms can converge with devastating consequences.
Our Take: Risk, Response, and Accountability
What Worked Under Pressure

Their bravery and selflessness are to be commended, and their actions provide a model for how to respond to such emergencies in the future. The police and emergency responders were able to respond quickly because of their training and experience, and their actions demonstrate the importance of having well-trained and well-equipped emergency responders. According to the San Jose Police Department, the response time was approximately 3 minutes, which is a testament to the effectiveness of the emergency response plan.
Community Support: The community came together to support the victims and their families, with organizations such as the American Red Cross and the San Jose-based non-profit, the Silicon Valley Community Foundation, providing financial and emotional support. The community's response to the shooting demonstrates the importance of having a strong and supportive community, and it provides a model for how to respond to such tragedies in the future.

Increased Security: The VTA increased security measures at its facilities, including the installation of metal detectors and the hiring of additional security personnel, as recommended by the Transportation Security Administration (TSA). The VTA's decision to increase security measures demonstrates the importance of taking proactive steps to prevent gun violence, and it provides a model for how to improve workplace safety and security. The VTA's increased security measures include the installation of CCTV cameras and the implementation of a new emergency response plan, which was developed in consultation with the Federal Bureau of Investigation (FBI) and the San Jose Police Department.
What Failed Before Impact
Lack of Gun Control: The shooting highlights the need for stricter gun laws and better background checks, which could have potentially prevented the tragedy. The lack of effective gun control measures in the United States is a major contributor to the high rate of gun violence in the country, and it is an issue that must be addressed in order to prevent similar tragedies from occurring in the future. According to the Gun Violence Archive, a non-profit organization that tracks gun violence in the United States, there were over 40,000 gun-related deaths in the United States in 2021, highlighting the need for stricter gun laws and better background checks.
Workplace Violence: The shooting was a tragic reminder of the dangers of workplace violence, which can be prevented with better workplace safety and security measures, such as those recommended by the Occupational Safety and Health Administration (OSHA). The VTA rail yard shooting demonstrates the importance of having effective workplace safety and security measures in place, and it highlights the need for employers to take proactive steps to prevent workplace violence. The VTA's decision to increase security measures at its facilities is a step in the right direction, but more needs to be done to prevent workplace violence, including the implementation of a workplace violence prevention policy, as recommended by the National Institute for Occupational Safety and Health (NIOSH).
Mental Health Issues: The shooting highlights the need to address mental health issues, which can contribute to gun violence. The VTA rail yard shooting demonstrates the importance of having effective mental health services in place, and it highlights the need for employers to take proactive steps to support the mental health of their employees, such as providing access to counseling services, as recommended by the American Psychological Association (APA). The VTA's decision to provide counseling and support services to its employees is a step in the right direction, but more needs to be done to address mental health issues and prevent gun violence, including the implementation of a mental health awareness program, as recommended by the National Alliance on Mental Illness (NAMI).
Systemic Failure: The shooting was a result of a systemic failure to address the root causes of gun violence, including mental health issues and social isolation, as highlighted by the National Institute of Mental Health (NIMH). The VTA rail yard shooting demonstrates the importance of having a comprehensive approach to addressing gun violence, and it highlights the need for a multifaceted approach that includes stricter gun laws, better background checks, improved workplace safety and security measures, and effective mental health services. The VTA rail yard shooting is a reminder that gun violence is a complex issue that requires a comprehensive solution, and it highlights the need for policymakers to work together to address the root causes of gun violence, including the implementation of evidence-based policies, as recommended by the Centers for Disease Control and Prevention (CDC).
We keep coming back to one thing: the haunting fact that Samuel Cassidy's coworkers had reported his erratic behavior over the years, including complaints about surveillance and perceived workplace injustices, yet he was still able to legally purchase a 9mm Smith & Wesson handgun in 2016. The 240-page police report and the subsequent settlement of the civil lawsuit filed by victims' families for $4.5 million are stark reminders of the gaps in how public agencies handle internal threats. As we reflect on the VTA shooting in 2026, five years after the tragedy, the names of the nine victims—Paul Delacruz Megia, Taptejdeep Singh, and seven others—remain etched in our memory, a somber reminder that the convergence of workplace culture, mental health, and access to firearms can have devastating consequences. The VTA shooting will forever be a painful lesson in the deadly cost of unchecked warning signs.
