New Orleans police said first responders swiftly converged on the area and the department tweeted out calls for crowds to avoid the site. The float, with its gaudy lights still twinkling, was halted with police cordoning off the area on horseback and on foot. All around, streets were lined with tossed beats, trinkets and the debris of the street party, and TV stations reported a somber mood had taken hold of members of the parade krewe upon learning of the fatality.

The fatality comes as New Orleans had already been mourning the death of a 58-year-old woman who — witnesses said — was run over by a parade float Wednesday night in the runup to Mardi Gras.

That death occurred during the parade of the Mystic Krewe of Nyx, an all-female Carnival group. Witnesses said the woman, later identified by authorities as New Orleans native Geraldine Carmouche, had apparently tried to cross between two parts of a tandem float and tripped over a hitch connecting the sections.

Mardi Gras concludes with the Fat Tuesday celebration in coming days that marks the raucous climax of a week or more of parades and parties each year.

The 2020 Carnival season deaths come just a year after a car sped into a bicycle lane near a parade route, hitting nine people and killing two bicyclists not far from where the Krewe of Endymion formation had just passed. A man identified as the driver was subsequently charged with two counts of vehicular homicide.
