It wasn’t immediately clear how he fell or whether he was a resident or worker. 

The fatal window washing incident was the second serious fall from a building Monday.

ABC7 reported that a 7-year-old autistic girl climbed out of the fourth-story window of her Bronx apartment, tumbling from the fire escape.

That fall took place on Andrews Avenue in University Heights just after 2 a.m., ABC7 added. 

Despite landing on “hard pavement,” according to the news station, the girl survived, and was taken to the hospital in stable condition. 

Police are not certain whether she fell from the window or climbed down the fire escape before falling.
