Three people have pleaded guilty in connection to the death of a New York City girl whose remains were found in a Monmouth County park more than eight years ago.

The case came to be known as the "Baby Bones" case after the girl's skeletal remains were discovered in Upper Freehold Township in 2005.

She was later identified as Jon-Niece Jones, a 9-year-old who died in New York in 2002.

On Thursday, the girl's 39-year-old aunt, Likisha Jones, and her husband, Godfrey Gibson, of Manhattan, pleaded guilty along with the girl's 36-year-old uncle, James Jones, of Brooklyn, to hindering apprehension of another and conspiracy to hinder apprehension of another.

The cause of the girl's death is still being investigated.

Prosecutors are expected to ask that the defendants receive probation.
