NEW YORK (AP) — Their job was one of routine peril — washing windows on Manhattan skyscrapers.

The danger proved deadly for Edgar Moreno and nearly so for his brother. Their work platform gave way as they stepped onto it Friday from the roof of a 47-story Upper East Side apartment building, sending them on a horrifying plunge to a plaza below.

"They apparently fell all the way from the top," Fire Department spokesman John Mulligan said.

Moreno, 30, of Linden, N.J., was pronounced dead at the scene. His 37-year-old brother, Alcides Moreno, remained hospitalized Saturday at New York Weill Cornell Medical Center. A spokeswoman declined to release details on his condition at the family's request.

Authorities were investigating the accident, but a buildings official said the workers apparently were not wearing safety harnesses.
