A New Jersey postal worker discovered a cryptic message and a sealed mailbox at a home on his route Friday, which led police to find the bodies of three elderly individuals inside. Don Clements, the postal worker, told the New York Post that he found a sign on the door of the ramshackle home that read "9-1-1 Inside" above drawings of two sad faces with X's for eyes.

Clements stated that he found the situation peculiar because he is the only person who visits the house daily, and the sign would only be visible to him. The mailbox was also sealed with clear wrapping tape, the same tape used for the sign.

"The only person who goes up to the door is the mail carrier," Clements reiterated. "It's weird. The whole situation was weird."

Upon arriving at the scene, police discovered a bloody interior and the bodies of three individuals. The identities of the deceased have not yet been released by the Burlington County Prosecutor's Office. Neighbors have described the occupants as a reclusive family of siblings who largely kept to themselves. One neighbor mentioned that one of the siblings used to be a crossing guard for the town, while another brother would regularly walk to a nearby store.

David Babcock, a neighbor, told NBC 10 that one of the brothers had worked at a local department store for 40 years. Babcock also stated that he was not surprised that something bad had happened at the home, but he never expected his neighbors to be found dead. He added that he had thought the house might be condemned and the occupants sent to a group home.

Another neighbor recalled seeing someone leave the house with a small bag of trash on a Tuesday, which was unusual as she had never seen anyone enter or exit the home before, except for one brother who made daily trips to a convenience store. This individual was wearing all black.

The prosecutor's office has stated there is no ongoing threat to the public, and autopsies are pending to determine the cause of death for the three individuals. Clements expressed that he was shaken by the disturbing discovery, noting the bizarre nature of the sign and the overall unusual circumstances.
