Bunnyhop, it was said on News12 last night, reporter said "a huge police presence" and the entrance to the park and Wantagh State Parkway was closed. I know the area somewhat. Just from other things that happen on LI, anytime a cop is involved, for example a fatal car accident, there are hours of investigation at the scene. Of course this is only a thought,nothing to base it on. But I got a really bad feeling when I saw the report. Also body was found near a bike path in a heavily wooded area.
Mill Pond Park is a bit more SW. Merrick Rd.
let's see if this works:
