NEW YORK — More than two decades after the body of a young girl was found inside a cooler, the New York Police Department is seeking help identifying the victim dubbed "Baby Hope."

On Tuesday, the 22nd anniversary of the discovery, police offered a $12,000 reward for any information leading to an arrest and conviction in the unsolved crime.

Officers put up posters and handed out fliers with sketches of how the victim might have looked.

The cooler was found in Washington Heights, on an embankment off the Henry Hudson Parkway.

The girl was believed to be between 3 and 5 years old. Tests showed she was malnourished and had been sexually abused.

DNA testing has yielded no matches with databases of convicted felons or active missing person cases.
