Buried Treasure

We had just moved in to a nice house in a small community. 

As we were putting our belongings inside, I had discovered a note that stated, "In the basement: 18 ft. exactly east, 3 ft. to the exact right, 5 ft. below, buried treasure worth 1.5 million." 

After researching and finding out the former owner used to always be "exploring the lake," we decided this was real and began our digging of the treasure.  

Turns out, there really was a chest buried down there. 

But shockingly, when we opened the chest, we found rotting corpses and a note stating,"Katherine, Jimmy, Ann, each four years old and worth $500,000."
