Is mariposa school haunted

The reason i deleted that person's answer was because I dont think ANY of us could understand that language.. before I begin I would like to apologize in advance for my computer skips letters and spaces occasionally and I might not catch it. :) Okay heres the story:

So I went to Mariposa Elementary School in Redlands, CA. I was promoted to Moore MS about 2years ago...im 13 years old. In the 6 years I went there, you should believe how many rumors went around that it was haunted.."If you knock on the nurse's door, Billy knocks back! O:" but I have never tried it, so I cant say that is true or not.. but i do know that a boy named Billy was hit by a car when on his scooter. It was aftr school hours but on Mariposa campus, so he didnt technically die at school in the nurse's office or whatever.. when i was in 2nd grade, a interviewer from "Most Haunted" came and talked to my teacher, Mrs. Hodges, and she didnt give them any information. My 23yr old sister, Amy (name changed) and her friend went to Mariposa at night a few years ago and decided to really settle this whole thing. They ran to the swings and they were swinging by themselves as if a child was playing on them. There was no wind and no other evidence of something nature-wise that could push the swings. I truly believe that Mariposa is haunted.
