A femur and a couple of smaller bones were found just after midnight Wednesday near the carousel.
The discovery comes after patrol officers found a skull and bones on Monday morning in the park.
The remains appear to be from the same person, detectives have been told.
The Medical Examiner's Office says a full forensic anthropological examination is underway.
On Wednesday morning, parkgoers seemed surprised by what had been found.
"You don't usually see that nowadays honestly, it feels like something from the 1970s or so, but you live and learn every day," one parkgoer said.
The victim's identity has not yet been released.
