Port Authority is investigating the area surrounding LaGuardia Airport, where skeletal remains were found on Tuesday evening.   Skeletal remains were last found near LaGuardia in 2012. The circumstances of that investigation were very similar to those of this week's. They were both found near the gate that separates the airport from the Flushing Bay.   It is possible that the remains were exposed by harsh rain and winds, according to authorities.   #nyc #queens #laguardia
