In 2014, anonymous letters began showing up in the mailbox of Derek and Maria Broaddus, who had just bought a house on 657 Boulevard in Westfield, New Jersey, signed by someone who called themselves “The Watcher.”
In his notes, The Watcher detailed their apparent reconnaissance of the property and the Broadduses’ short time at it (they had only just closed on the house and hadn’t yet moved in). The first letter thanked the family for bringing children to the home—“young blood,” as the letter so terrifyingly put it—and stated that once The Watcher knew their names, they would call to the children and draw them closer.
After the Broadduses received two more hair-raising letters from The Watcher over the next few weeks, a police investigation was launched into the matter. The couple never moved into the house and spent countless amounts of money on mortgage payments and property taxes while trying to unload it. Their story was chronicled by New York magazine in late 2018, after which the case became highly publicized. Still, between a local investigation, private detectives, and amateur sleuths, no culprit was ever found.
