A family has been forced to flee their new $1.3 million home in Westfield, New Jersey, after repeatedly receiving threatening packages from a person who calls themselves “the Watcher,” according to a lawsuit filed against the previous owners of the home.

CBS New York reports that the packages are from someone who claims the six-bedroom home “has been the subject of my family for decades.”

“I have been put in charge of watching and waiting for its second coming,” one of the letters reportedly reads. Two others allegedly refer to the couple’s young children. “I am pleased to know your names now, and the name of the young blood you have brought to me,” one reportedly says. Another asks, “Have they found out what’s in the walls yet?”

The couple has filed a lawsuit against the previous owners, who they claim failed to inform them about “the Watcher” before the sale, despite being aware of the individual. Westfield’s mayor says the letters have been classified as a disorderly person’s crime.

“Our police department conducted an exhaustive investigation based on the factual circumstances and evidence available,” Mayor Andy Skibitsky said.
