The gunman in the Washington, DC, gym shooting is a wealthy doctor who had been locked in a battle over black mold in his $1.1 million penthouse — and cited a report about it as his chilling “manifesto.”
Dr. Matt Lambert, an emergency room doctor, had sued his homeowners association in March 2025, claiming that scaffolding from repairs on his trendy Logan Circle building led the dangerous fungus to spread.
“My manifesto is an engineering report,” an X account linked to Lambert tweeted at 8 a.m. Thursday— minutes before he opened fire inside his building’s ground-floor gym, killing at least one person.
He attached a report that cited “suspected microbial growth,” along with water intrusion and a hefty bill to “rehabilitate” the wall of his swank home.
“Two years of living in luxury (and the start of 6 months with no shower, dryer, HVAC, and cooking),” he posted Wednesday, along with pictures of renovations in the unit.
Lambert allegedly killed one person and left four others injured in Vida gym, where he is believed to have been a member, according to police.
He then ran back up to his penthouse and barricaded himself before taking his own life, police said.
Lambert lived on the seventh floor of 1515 15th St. NW, dubbed “one of DC’s most desired buildings” with “chic, open living spaces” by the real estate firm Redfin.
DC police said they were investigating a conflict with the homeowner’s association as the reason behind the shooting.
Lambert — who had been fighting with the Metropole Condominium Association over mold problem since August 2024 —developed an apparent obsession with alleged “leaks, mold and rodent infestation” in the building, ranting about it dozens of times on X in recent months.

Mold Rage!
I have heard worse excuses. Maybe he can claim mold insanity.

What happened to the “do no harm” in the Hippocratic Oath?
Lol.
Uh...the insane was strong with this one.
Why shoot up the local gym if his beef was with the hated HOA? Very odd. Perhaps a few relevant details have been omitted.
Homo derangement syndrome.
GREAT! Dead demented Dr.
One too many 15s and *snap*.
It would be ironic if the company that comes in to clean up the penthouse apartment filled with blood and brain matter ends up also solving the mold problem.
I’m definitely getting that vibe
Racist.
I really shouldn't joke about it; I spent 10K on a three-day tenting for black mold from the fourfold hurricanes in 2004. I hope his soul is at rest.
I wondered about that too. Some of those shot may have been tenants, trying to stay healthy, in spite of Big Mold.
For some folks, living alone (with no one around to tell him how crazy he had become) brings out the worst in them.
I get it. All that money spent on a home so you can relax in some stylish comfort after putting in the long, stressful hours as an emergency room doctor. Only to be put off like some flake in digs that are low-rent or rent-controlled. You just want professionals (like yourself) to do a professional job clearing up an easily identifiable and remedied problem. And then months go by and you’re paying on your place and paying the HOA and playing by the rules and still no resolution.
A guy like that I would have guessed to be engaging legal specialists to resolve it. Maybe he was and he reached his limit over what should have been a manageable problem. But his own option of last resort is not the way…
Everybody is a victim these days. And far too many of them go looking for revenge of some sort.
Living as a hermit in the woods is starting to look better and better.
Wow, good call.
“The shooting took place at the VIDA Fitness in the 1500 block of 15th Street, N.W., in Logan Circle, a neighborhood with a prominent LGBTQ community. The gym is also colloquially known as one of Washington’s “gay gyms.” Washington Blade
15-7+15⁄15=....oh no...9
And as we all know...there are 9 letters in Black Mold...
From another article, he hoped to catch the HOA President (or whatever they are) at the gym.
Abortion and Assisted Murder being legal.
Tell me that involved abuse of SSRIs and alcohol without telling me.
