It was a Tuesday afternoon in July. The fog hadn't quite burned off the Embarcadero. High up in the 101 California Street building—one of those polished, tiered skyscrapers that defines the San Francisco skyline—people were just finishing lunch or wrapping up meetings. Then, the elevator doors opened on the 48th floor.
Gian Luigi Ferri stepped out. He wasn't some random drifter. He was a 55-year-old mortgage broker who felt the world had cheated him. He carried a briefcase, but it wasn't full of papers. It was filled with hundreds of rounds of ammunition and two TEC-9 semi-automatic pistols.
The San Francisco shooting 1993 isn’t just a footnote in California history. It’s the reason your office probably has a security badge scanner. It’s the reason the "assault weapons ban" became a national shouting match in the nineties.
Honestly, looking back at the 101 California Street shooting today, it feels eerily modern. We’re so used to these headlines now. But in 1993? This shattered the city’s sense of safety in a way that’s hard to describe if you weren't there.
The Motive: A Grudge Against the Law
Ferri didn't pick the building at random. He was looking for the law firm Pettit & Martin. Why? Because they had represented him in some real estate deals years prior, and he blamed them for his financial ruin. He had a "hit list."
He started on the 48th floor. He moved down to the 47th.
It was a slaughter.
Ferri used "Hell-fire" triggers—little spring-loaded devices that allowed him to fire his semi-automatics almost as fast as a machine gun. He was methodical. He walked through glass-walled offices and conference rooms, firing at anyone who moved.

Eight people died. Six others were wounded.
The victims weren't just names on a police report. They were people like Jody Sposato, a young mother who was there for a deposition. They were lawyers like Jack Berman and Deborah Fogel. When the police finally cornered Ferri in a stairwell, he didn't surrender. He put a pistol to his own head.
He left behind a rambling, semi-coherent letter. It railed against the legal profession, the FDA, and even the "unfair" advantages of certain ethnic groups. It was the manifesto of a man who had completely detached from reality, yet had the chilling focus required to stockpile high-capacity magazines and plan a tactical assault.
How the 101 California Street Shooting Changed American Law
You can't talk about the San Francisco shooting 1993 without talking about the politics that followed. It was a lightning rod. At the time, Senator Dianne Feinstein—who had been the Mayor of San Francisco during the Milk/Moscone assassinations—was already pushing for stricter gun control.
This tragedy gave her the leverage she needed.
The TEC-9 used by Ferri became the "poster child" for the 1994 Federal Assault Weapons Ban. People were horrified that a civilian could walk into a store and buy a weapon designed for high-volume fire. It felt like a loophole that had finally caught up with society.
The 101 California Street shooting also birthed the "Legal Community Against Violence," which eventually became the Giffords Law Center to Prevent Gun Violence. It turned a bunch of corporate lawyers into activists. They realized that their high-rise offices weren't fortresses.

Security Changes You See Every Day
Before this event, most office buildings in downtown SF were open. You could just walk in, wave at a receptionist, and take the elevator to the 50th floor. That ended in July 1993.
- Turnstiles and Badges: The transition to "closed" lobbies started here.
- Panic Buttons: Law firms began installing silent alarms under reception desks.
- Active Shooter Drills: While common now, the concept of "Run, Hide, Fight" started to permeate corporate HR manuals after this massacre.
It changed the architecture of work. We stopped building "open" public spaces in high-rises and started building checkpoints.
The Legacy of the Victims
We often remember the killer’s name and forget the people whose lives were cut short. It’s a weird quirk of true crime history. But in San Francisco, the names of the "101 California Eight" still carry weight.
There was John Scully, who died while shielding his wife, Michelle. He was only 28.
There was Allen Berk, a partner at the firm who was widely respected in labor law.
When you look at the fallout, the 101 California Street shooting didn't just kill eight people; it effectively killed the law firm of Pettit & Martin. The trauma was too much. The firm, which had been a powerhouse in the city, never really recovered its spirit. They disbanded just a few years later in 1995. Partners left. Associates couldn't stand being in the building. The "energy" was gone.
It's a reminder that workplace violence has a "half-life." It lingers in the carpets and the walls long after the police tape is taken down.

What Most People Get Wrong About the 1993 Shooting
A lot of people think this was the first mass shooting in a "gun-free" zone. It wasn't. But it was one of the first times we saw "high-capacity" magazines used so effectively in a confined urban space.
Another misconception? That the police were too slow.
The SFPD actually arrived incredibly fast. But the way high-rises are built—the maze of hallways, the fire stairs—made it a nightmare for the tactical teams. They had to clear the building floor by floor while not knowing where the shooter was. It was a tactical disaster waiting to happen.
Today, police departments use floor plans and digital "blueprints" of major skyscrapers. In 1993, they were flying blind.
Actionable Insights for Modern Safety
While the San Francisco shooting 1993 feels like a different era, the lessons are unfortunately timeless. If you work in a high-rise or a corporate environment, there are things you should actually know.
- Know the Stairwells: Most people in 101 California didn't know which stairs led to the street and which led to a mechanical dead end. Look at your floor plan tomorrow.
- The "Badge-In" Culture: Don't let people "piggyback" through security doors. It feels rude to shut the door on someone, but Ferri got into that building because he looked like he belonged there.
- Mental Health Intervention: Ferri had been spiraling for years. He had sent threatening letters. In the modern era, "Threat Assessment Teams" in workplaces are designed to catch these red flags before the elevator doors open.
The 101 California Street shooting remains a dark pillar of San Francisco's history. It changed the way we work, the way we vote, and the way we view the safety of the "white-collar" world. It proved that no matter how high up you are in a skyscraper, you aren't untouchable.
To honor the history of this event, the best thing anyone can do is stay aware of their surroundings and support workplace safety initiatives that prioritize people over optics. The tragedy of 1993 wasn't just that it happened, but how much it changed the DNA of the American office forever.
