Quoting myself to provide a link as a visual to show the park and address from the article are in Manhattan. Bronx is across the river. The article is wrong.

Fort George Ave is the one that curves like a half-circle. Amsterdam Ave is a straight street. Highbridge Park is along the east side of upper Manhattan. The neighborhood across the river in the Bronx is also called Highbridge.
Both areas are named after the High Bridge that connects the Bronx to Manhattan. The body was found on the Manhattan side.
Sorry to be a stickler....but I know this neighborhood a bit!
