The Yonkers School District was on high alert Wednesday after Facebook posts surfaced Tuesday night threatening the well being of students and staff after similar "Crazed Clown" incidents in Mount Vernon, New Rochelle and Port Chester. The concerning national trend made its way to Yonkers on Tuesday after a screenshot was posted of the Casimir Pulaski School on social media with a message from the "Yonkers Clown" saying everyone there was going to die on Wednesday.
