BUFFALO, N.Y. — The body of a Buffalo Sewer Authority contractor has been recovered on Bird Island.

Officials say the man fell 15-feet down a well which is part of a system that connects to the Niagara River.

Police say he was not anchored to anything when he fell on Thursday.

The search eventually turned into a recovery mission, which was suspended Thursday night.

So far, authorities are not sure exactly what the man was doing when he fell.

An OSHA spokesperson tells Spectrum News they have opened an investigation and an inspection is ongoing.

The man's name has yet to be released.
