It happened on a Monday. Most people in the quiet, coastal town of Goleta, California, were winding down their evening when the news started trickling in about something horrific at the local mail plant. This wasn’t just another tragedy. The Goleta postal facility shootings remain one of the most chilling examples of workplace violence in American history, mostly because it broke every "profile" we thought we understood about these events.
Honestly, when we talk about "going postal," people usually picture a disgruntled man in a uniform. But in January 2006, the person behind the 9mm Smith & Wesson was 44-year-old Jennifer San Marco. She was a former employee who had been pushed out years prior due to mental health issues. Her return to the Santa Barbara Processing and Distribution Center wasn't a snap decision; it was a calculated, haunting final act that took the lives of seven innocent people before she turned the gun on herself.
The Night Everything Changed in Goleta
The timeline is actually pretty terrifying once you look at the details. Before she ever set foot on the postal grounds that night, San Marco stopped at her old condominium complex in Santa Barbara. Around 7:15 p.m., she shot her former neighbor, 54-year-old Beverly Graham. They’d had disputes in the past—Graham had apparently complained about San Marco’s loud singing years earlier—and this seems to have been the first stop on a revenge tour.
By 9:00 p.m., she was at the Goleta facility.
Security was supposed to be tight, but she knew the system. She tailgated another car through the electronic gate and then used a 9mm pistol to force an employee to hand over their ID badge. She let that person go. Then, she started walking.

The parking lot became a crime scene in seconds. Ze Fairchild, 37, and Maleka Higgins, 28, were the first to fall. Nicola Grant, 42, was shot next. Inside the building, the chaos was muffled by the roar of mail-sorting machinery. Most workers were wearing ear protection. They had no idea their colleagues were being executed just a few yards away.
Why the Goleta Postal Facility Shootings Defied the Profile
Criminologists like James Alan Fox have pointed out that this event was an anomaly. Most workplace shooters are men who tie their entire identity to their job. When they lose that job, they lose their "manhood" or sense of self. San Marco was different. She was a woman, and her descent into violence was steeped in a very specific, documented type of paranoia.
The Warning Signs Nobody Could Fix
San Marco didn't just "snap." Her history was a trail of red flags that the system simply wasn't equipped to handle in 2006.
- 2001: She was removed from the facility by police for "strange behavior" and placed on a 72-hour psychiatric hold.
- 2003: She was retired on psychological disability after being found crawling under a mail-sorting machine.
- The New Mexico Years: After leaving California, she moved to Milan, New Mexico. There, she became known as the "crazy lady" who talked to herself, shouted at nothing, and once even stripped naked at a gas station.
She even tried to start a publication called "The Racist Press." Her writings, later found by investigators, were a mess of conspiracy theories involving the U.S. government, the Ku Klux Klan, and David Berkowitz (the "Son of Sam"). She believed the postal facility was the center of a plot against her.

A Question of Motive: Racism or Paranoia?
There’s a lot of debate about why she chose those specific victims. Every single person she killed at the facility was a person of color. Ze Fairchild, Maleka Higgins, Nicola Grant, Dexter Shannon, Guadalupe Swartz, and Charlotte Colton.
Was it a hate crime? Or was it just that the night shift at a California mail plant happened to be diverse?
Authorities never officially labeled it a hate crime, but the writings she left behind were filled with vitriol. She had a list of over 100 "offenses" she felt people had committed against her. Some people think she was targeting the facility as an institution; others are convinced she was hunting based on race. Honestly, it was probably a toxic mix of both, fueled by a brain that had completely lost its grip on reality.
The Victims We Should Remember
While the media often focuses on the killer, the families in Goleta and Lompoc lost pillars of their community.

- Guadalupe Swartz: A 52-year-old mother who had recently lost her husband to cancer. She tried to run, but San Marco was too fast.
- Charlotte Colton: A 44-year-old supervisor and mother of three. She survived the initial shot but died two days later at the hospital.
The Security Failure That Still Stings
One of the biggest takeaways from the Goleta postal facility shootings was how easily she bypassed security. Tailgating a car into a "secured" lot is a trick as old as time, and yet it worked perfectly. In the aftermath, the USPS had to do a massive audit of its facilities.
They realized that having a badge-entry system doesn't matter if an armed person can just take a badge from a terrified employee in the parking lot. Today, you'll see more cameras, more physical barriers, and much more aggressive "active shooter" training for postal workers. But back then? It was a different world.
It's kinda wild to think that even with a history of being escorted out in handcuffs, San Marco was able to buy a 9mm pistol in New Mexico just months before the shooting. She passed the background check. Why? Because she had never been permanently committed to a mental institution. She had only been held for 72 hours. In the eyes of the law in 2005, she was a "qualified" buyer.
Practical Lessons for Workplace Safety Today
We can't change what happened at the Goleta plant, but the tragedy changed how HR departments and security teams look at "separated" employees. If you're looking for actionable ways to prevent this kind of thing in a modern workplace, it basically comes down to these three things:
- Formalize the Separation Process: When an employee is terminated or leaves on disability for mental health reasons, their access shouldn't just be "turned off." Security needs a photo, a profile, and a clear protocol for what to do if that person shows up in the parking lot.
- The "Tailgating" Culture: Most people are polite. We hold doors. We let cars follow us through gates. This "politeness" is a massive security hole. Training employees to never let someone follow them into a secure area is basic, but it saves lives.
- Behavioral Intervention Teams: Instead of just calling the cops when someone acts "weird," many large organizations now use threat assessment teams. These groups look at the "trail of breadcrumbs"—the ranting emails, the strange behavior—to intervene before the person ever reaches for a weapon.
The Goleta postal facility shootings serve as a grim reminder that workplace safety isn't just about fire drills. It's about recognizing the humanity—and the sometimes-fractured mental health—of the people we work beside every day.
To honor the memory of the victims, you can support organizations that focus on workplace violence prevention and mental health advocacy. Understanding the "path to violence" is the only way to ensure that a Monday night in a mail plant never turns into a national tragedy again. Be sure to check your own workplace's emergency action plan and ensure that local law enforcement has up-to-date floor plans of your facility to speed up response times in a crisis.
