Update on the Noah Webster Grave Fire

I found the following update on the fire at the grave of Noah Webster:

"The New England Society for Paranormal and Phenomenology Studies was working in the area of the grave of Noah Webster and picked up disturbing vibrations and noises the day before the fire started. We've been in contact with the police with our findings and will work with them in this matter". (http://groups.yahoo.com/group/nespps/)

I don't know what it means, but I'm intrigued.
