He thought it was a doll. Or maybe a mannequin. But the last thing a man walking his dog in a Brooklyn Park expected was a dismembered woman’s body. Police say after the man saw the body he called them from home,perhaps really realizing what he’d seen. She was found face down, no arms or legs. Today New York is a surprisingly safe city, so a dead body alone would have been a shock, but dismemberment is rare. The New York Times had few other details as of early Tuesday morning.
