The New York Police Department is seeking help identifying the body of a young girl dubbed Baby Hope, whose naked and malnourished body was found inside a cooler 22 years ago.

Police are offering a $12,000 reward for any information leading to an arrest and a conviction.

This week, officers put up posters and handed out fliers with sketches of how the girl looked in 1991 and might look now. Cold-case detective Robert Dewhurst says he hopes someone who knew her will come forward.

The cooler was found in Washington Heights on July 23, 1991, on an embankment off the Henry Hudson Parkway.

The girl was believed to be 3 to 5 years old. DNA testing has yielded no matches with databases of convicted felons or active missing-person cases.
