Shannon Burton, the principal at Milton L. Olive Middle School in Wyandanch, called his former gal pal and allegedly seethed, “I’ll f–k up your boyfriend. Wait until I catch him. How can you do this to me? You’re f—ing this guy,” on July 25, according to a criminal complaint. Burton made 15 other calls to his ex and rang her doorbell multiple times over several hours — after creepily tracking down her address, according to the Manhattan District Attorney’s office. The former couple split at the end of 2023.  In one phone call, the accused creep said, “I just saw you leave your apartment” as she headed out the door with her boyfriend.
