The veteran actress, born in New York and raised in Brooklyn before moving to L.A., moved seamlessly from the big and small screens throughout her decades long career.

Police officers, responding to a 911 call, found her unresponsive in a Manhattan apartment on Wednesday morning, the authorities said.

Michelle Trachtenberg, the actress who rose to fame as a child star with films like “Harriet the Spy” and went on to have memorable roles on TV shows including “Gossip Girl,” has died, according to an NYPD source.
