Just four days after the last day of classes, an exterminator investigating a “foul odor” found the shocking source of the smell inside a New York City school’s chimney: a decomposing body.  Investigators are now trying to determine if any construction workers in the area are missing, as the school was under renovations.  Police are also looking into whether foul play may be involved.  While there were no students or teachers inside the building at the time of the macabre discovery, several students have told reporters they’d been complaining of a bad smell for weeks leading up to the last day of school.
