An NYPD spokeswoman initially told Fox News that upon arrival, officers observed an unconscious and unresponsive male at the location with "severe body trauma." An NYPD source later confirmed reports by local outlets that said the remains included "body parts" on the highway. 

EMS responded and pronounced the victim deceased at the scene. No arrests had been made as of Sunday early afternoon. 

The deceased individual is unidentified at this time, the spokeswoman said when contacted Sunday. The investigation is ongoing by the NYPD Collision Investigation Squad. Few details have been confirmed about the incident – including how long the remains were believed to be in the roadway, as police were called to the scene in broad daylight.
