Volunteers searching Tuesday for a missing Juilliard (search) student discovered the decomposed body of a woman in a park in upper Manhattan, police said.

The body had not been officially identified as that of 21-year-old Sarah Fox (search). But police said it partly matched the description of the missing woman, who lived near the park.

A civilian search party found the body in a wooded area below the Henry Hudson Parkway in Inwood Hill Park (search), police said.

Fox, who grew up in Pennsauken, N.J., was last seen May 19 leaving her apartment in workout clothes. Friends said she may have been going for a run in the park, or to a gym on 181st Street.
