The baby, thrown from a second-floor window, was found alive in a nearby trash can and then rushed to a hospital, but it could not be saved, authorities said.

The Paris prosecutor’s office said the infant was given emergency medical care, but did not survive. An American woman was being held in police custody in Paris on Monday following the death of a newborn baby, who was thrown from the window of a hotel in the 20th arrondissement, authorities said.
