WESTFIELD, N.J. - It was a million-dollar dream home for one New Jersey family, located in picturesque Westfield, New Jersey -- until the letters started showing up.

The threatening notes were signed by someone calling himself "The Watcher," and the messages were so disturbing they forced the family out of the $1.3 million, 6-bedroom home, leaving the rest of the town on edge.

The troubling messages are detailed in a lawsuit against the former owners, the real estate company, and others. The plaintiffs, Derek and Maria Broaddus, claim the previous owners were so desperate to sell the house they covered up knowledge of the terrifying letters.

After moving in to the spacious new home, the couple say they received the first letter in May of 2014, informing them that the home "has been the subject of my family for decades," and that "I have be (sic) put in charge of watching and waiting for its second coming." The letter was signed, "The Watcher."

"I asked the Woods (the previous owners) to bring me young blood," the letter menaced. "Have they found what is in the walls yet? In time they will."

"Who has the bedrooms facing the street? I'll know as soon as you move in . . . then I can plan better," the chilling message read. "I am pleased to know your names now and the name of the young blood you have brought me."

"It is now my time . . . you don't want to make 657 Boulevard unhappy," The Watcher wrote, adding that his father and grandfather had watched the house before him.

The first letter was followed by two others, and left the couple "consumed daily by stress, anxiety, and fear regarding what 'The Watcher' will do," according to the suit.

Since news of The Watcher reached the rest of the town, and any prospective buyers, the Broaddus' have been unable to sell the house.

"Our police department did go the extra mile, including consulting with the Union County Prosecutor's Office, to make sure no stone was left unturned," said Westfield Mayor Andrew Skibitsky at a recent township council meeting. "Such efforts have not, however, yielded information leading to charges."

The letters, which Skibitsky emphasized were received a year ago, are being treated as a disorderly persons offense.

No arrests have been made.
