Police say Dr. Matt Lambert, 55, fatally shot James Stuart, his condo building manager, at a Washington gym on Thursday, and four others were wounded. Reports say Lambert died by suicide. The New York Post reports he vented online about the state of his condominium for 14 months, including posts about mold, and published a manifesto before the attack. The Independent reports he gave a reporter an ominous quote about mold months earlier. The Daily Caller, citing that reporter, reports he also referenced Luigi Mangione.
