DC doctor accused of killing condo manager in gym after years-long mold dispute

Key points

• Lambert is accused of shooting Stuart inside a VIDA Fitness gym after waiting over an hour for him to arrive.
• Lambert then fled to his seventh-floor condo, fired from a balcony, cut a gas line, and started a fire before killing himself.
• One victim remains in critical condition; three others have non-life-threatening injuries, and a fifth victim was grazed.
• Lambert had sued his homeowners' association in March 2025 over mold and water damage, alleging negligence.
• Lambert's attorney, Joel Braithwaite, stated Lambert spent over $300,000 on legal fees and maintenance since 2024.

Background

Lambert purchased his $1.1 million Logan Circle penthouse in 2016. Problems began in 2023 after the condo association performed façade repairs. Lambert alleged water intrusion and mold appeared by 2024, leading to a lawsuit. The dispute was ongoing when the shooting occurred.

How outlets are covering it

USA TODAY and ABC News emphasize the premeditated nature of the attack, citing Lambert's social media posts and the hour-long wait at the gym. NBC4 highlights the community impact, noting Stuart was a 15-year gym member and beloved by colleagues. The Washington Post focuses on the displacement of neighbors, who were barred from their homes after the building was deemed uninhabible. Lambert's attorney, Joel Braithwaite, expressed shock, stating Lambert was not a violent person and that the dispute should have been resolved in court.

Why it matters

The case highlights the potential for property disputes to escalate into violence, raising concerns about the handling of maintenance issues and the mental health impacts of prolonged litigation and environmental stressors like mold.

What to watch

The investigation is ongoing. Neighbors are seeking temporary housing as the building remains closed. The legal dispute over the mold and water damage may continue, though Lambert's death complicates the proceedings.
