Environmental officials from New Jersey and New York have given up on finding the source of the mysterious smell that closed offices in Manhattan and sent a woman to the hospital in Jersey City. A search of more than 140 suspected site in the Garden State have yielded no clues to the source of the smell, and it’s being reported that investigations in New cork have also been fruitless.

The Post reports that an official stated that unless the smell returns, the investigation will be closed and classified unresolved.
