FROM EMERGENCY ROOM DOCTOR TO diᩚadℓy śh́óóting SUSPECT: DR. MATT LAMBERT KILLS BUILDING MANAGER AND WOUNDS FOUR IN WASHINGTON, D.C.

He was a physician who had spent years working in medicine and healthcare technology. But on a Thursday morning in Washington, D.C., a long-running dispute over his luxury condominium became the backdrop to a diᩚadℓy śh́óóting that left one man dead, four others injured and the suspected ɠυɳɱαɳ dead.

A 𝘴h☉𝔠king śh́óóting in Washington, D.C.’s Logan Circle neighborhood has left a community searching for answers after a 55-year-old physician, identified as Dr. Matt Wade Lambert, opened fire inside and outside a fitness center on November 12, 2026.

Authorities say Lambert killed 46-year-old James Stuart, the building manager of the condominium complex where he lived, before śh́óóting four additional people from his apartment balcony.

The incident ended when Lambert barricaded himself inside his seventh-floor condominium and fatally shot himself as police attempted to resolve the standoff.

Investigators believe the violence may have been connected to an ongoing dispute between Lambert and the building’s homeowners association over alleged mold, moisture and water damage inside his apartment.

A MORNING THAT TURNED INTO CHAOS

The śh́óóting began shortly before 8 a.m. Thursday at VIDA Fitness, located in the Metropole residential building in the 1500 block of 15th Street NW.

According to Metropolitan Police Department officials, officers received an emergency call reporting gunfire inside the gym.

Police arrived within approximately 30 seconds.

Investigators say Lambert entered the fitness center and shot James Stuart, the building’s 46-year-old manager.

Stuart was pronounced dead at the scene.

The ɠυɳɱαɳ then left the gym and returned to his condominium in the same building.

From his seventh-floor apartment balcony, he allegedly opened fire on people below, striking four additional victims.

The injured included two men and two women. One person remained in ᑕriᩚtiᩚcal condition, while the other three suffered injuries that were not considered life-threatening.

The entire attack unfolded in approximately five minutes, according to police.

A POLICE STANDOFF ENDS IN THE SUSPECT’S dєatᩚh

After the śh́óóting, Lambert barricaded himself inside his apartment.

Police established a security perimeter and deployed emergency response teams while negotiators attempted to communicate with him.

The situation became even more dangerous when Lambert reportedly fired through his apartment door and cut a natural gas line, starting a fire inside the unit.

Fire sprinklers helped contain the flames.

Officers continued attempting to communicate with him for approximately an hour.

Then they heard a gunshot from inside the apartment.

When police entered, they discovered Lambert suffering from what appeared to be a self-inflicted gunshot wound.

He was pronounced dead at the scene.

Authorities recovered three firearms from the apartment: a shotgun, a rifle and a handgun.

The investigation into how he obtained the weapons remains ongoing.

WHO WAS DR. MATT LAMBERT?

The identity of the suspected ɠυɳɱαɳ shocked many people who knew him professionally.

Lambert was a physician with a background in emergency medicine who had also worked extensively in healthcare technology and medical consulting.

He had lived in the Metropole condominium building above the fitness center.

Public records and court documents revealed that he had been involved in a lengthy legal dispute with the building’s homeowners association and property management.

The disagreement centered on alleged water intrusion, moisture problems and black mold inside his seventh-floor condominium.

THE $1.1 MILLION CONDOMINIUM DISPUTE

Court records show that Lambert purchased his approximately 1,200-square-foot condominium in 2016 for roughly $1.095 million.

In March 2025, he filed a lawsuit alleging that construction and exterior repair work had contributed to water damage and mold problems inside his home.

He claimed that the conditions had made parts of the property difficult or impossible to use.

Lambert also alleged that the problems had affected his health and sought financial compensation.

According to reporting by The Washington Post, he had spent more than $300,000 pursuing the dispute.

The condominium association and property management companies disputed responsibility for the alleged damage.

The legal case had not been fully resolved when the śh́óóting occurred.

Police Chief Jeffrey Carroll said investigators believed the conflict between Lambert and the building’s management was connected to the violence.

However, authorities emphasized that the investigation was still in its early stages.

THE VICTIM: JAMES STUART, 46

While much of the attention initially focused on the suspected ɠυɳɱαɳ, the tᩚraɢedy also claimed the life of a man whose family and colleagues are now grieving.

James Stuart, 46, worked as the building manager at the Metropole.

He was reportedly employed by EJF Real Estate Services for approximately 13 years.

The company released a statement expressing devastation over his dєatᩚh and remembering him as more than just a colleague.

His 𝘬iᩚlling has left his loved ones and coworkers mourning a life taken in an act of violence.

Authorities believe Stuart may have been specifically targeted because of the ongoing dispute between Lambert and the building’s management.

The four other victims were also left facing the physical and emotional consequences of the attack.

A COMMUNITY LEFT SEARCHING FOR ANSWERS

The śh́óóting triggered a massive police response throughout Logan Circle.

Nearby residents were instructed to shelter in place, and several schools temporarily placed students and staff on alert.

Businesses in the surrounding area were affected as officers secured the scene.

By late Thursday morning, authorities announced that the immediate threat had ended and the shelter-in-place order was lifted.

Investigators are continuing to examine the circumstances surrounding the śh́óóting, including Lambert’s legal dispute, his access to firearms and the events leading up to the attack.

FIVE VICTIMS, TWO FAMILIES FOREVER CHANGED

What happened in Logan Circle was more than a dispute between a condominium owner and building management.

One man lost his life. Four others were injured. The suspected ɠυɳɱαɳ also died.

For James Stuart’s family, the loss is permanent.

For the injured victims, the road to recovery continues.

And for the residents and witnesses who experienced the terrifying morning, the memories of what happened may remain for years.

A physician’s professional background, a costly property dispute and a diᩚadℓy act of violence have now become part of an investigation that has left Washington, D.C., with difficult questions.

No disagreement over a property can justify taking another person’s life. Our thoughts are with James Stuart’s loved ones and everyone injured or affected by this tᩚraɢedy.
