MASS TRAGEDY IN Midtown Manhattan (10022) : Gunman Kills 4, Then Himself in NYC Office Rampage – ID RELEASED

Midtown Manhattan (10022) – In a shocking act of workplace violence that has gripped New York City, police have identified the man who killed four people before fatally shooting himself inside a Midtown Manhattan office building. The gunman, 42-year-old Marcus DeWitt of Queens, was a former IT contractor reportedly disgruntled over a recent termination. Authorities say he entered the building at 515 Madison Avenue around 9:15 AM Monday with a legally purchased handgun and began shooting on the 12th floor.

The victims—two men and two women—were colleagues of DeWitt and included one department manager. NYPD officials confirmed that DeWitt had no prior violent criminal history, though a former coworker stated he’d become increasingly paranoid in recent weeks. The building was placed on lockdown for nearly three hours as police cleared each floor. DeWitt’s body was discovered inside a supply closet, dead from a self-inflicted gunshot wound.

Mayor Eric Adams called the shooting “a tragedy of unimaginable scale” and urged city businesses to revisit their security protocols. The NYPD is continuing to review surveillance footage, interview witnesses, and process the crime scene for further evidence. Family members of the victims are being notified, while grief counselors have been dispatched to the scene.
