Police in Davidson’s town of Floral Park, L.I., stood watch Saturday outside the home where the firefighter lived with his wife, Eileen, and their children — a 6-year-old son and three girls, ages 7, 3 and 1.

A neighbor dropped off a package and an envelope in the doorway of the otherwise quiet suburban home.

Davidson disappeared in the dense smoke and heavy flames as he and his colleagues pulled back from the basement, where his body was later discovered by distraught fellow firefighters.

His face mask was disconnected from its air regulator — the first step typically taken by a firefighter no longer getting air into his mask, the FDNY source said.

The other theory under consideration was that falling debris had dislodged the regulator during the chaotic response in the basement.

The firefighters union president, Gerard Fitzgerald, paid homage in advance of Tuesday’s funeral in St. Patrick’s Cathedral for the heroic first responder.

“Firefighter Davidson is a hero, and in his death embodies the title of ‘Bravest,’” said Fitzgerald. “His death is a reminder of the dangerous work New York City firefighters do every day in our city.

“Firefighter Michael R. Davidson’s sacrifice will never be forgotten,” he added.

Davidson was the son of a firefighter who worked in the same Harlem firehouse and the brother of Bronx Firefighter Eric Davidson — an 11-year FDNY veteran.

“Both of them worked at busy houses,” the source said. “They didn’t want to be on a quiet house in Staten Island. You go to these houses because you want to respond to fires.”

Davidson, who joined the FDNY in May 2003, was cited on four different occasions for bravery and life-saving actions on the job.

Before going to work Thursday, the firefighter spent his morning making a snowman with his kids outside their suburban Long Island home.
