The Museum of Modern Art has an odd mystery on its hands. First, somebody stole two photos of performance artist Carolee Schneemann worth $105,000 from a museum annex in Queens. Then somebody mailed them back, good as new. Now the NYPD has released surveillance video of the young woman believed to have done the mailing and is trying to track her down, reports People. Police traced the package with the photos back to a shipping store in Brooklyn, and the video shows a woman with a dark cap and glasses carrying the package into the store.
