Authorities discovered two different sets of human remains during a ghoulish 90-minute span Saturday morning in Brooklyn and Manhattan.
MTA Bridge and Tunnel Authority workers discovered the partially clothed skeletal remains around 8 a.m. near Fort Hill Place and Dahlgren Place in Bay Ridge, Brooklyn, cops said.

The maintenance crew came across the bones while they were cleaning up debris inside a grassy, wooded area near the Brooklyn-bound exit for the Verrazzano-Narrows Bridge, sources familiar with the case told the Post.
The victim appeared to be wearing a blue shirt, dark-colored pants and sneakers at the time of death, the sources said.
The city Medical Examiner’s office will confirm the remains are human and determine the cause of death.
About 90 minutes later, NYPD Harbor Unit cops discovered a second body floating in the East River underneath the Brooklyn Bridge near the Manhattan side, authorities said.
The fully-clothed body, which was moderately decomposed, showed no immediate signs of trauma, cops said.
Police are still working to identify the man, who was not carrying ID when he was found.
