BOK Tower Haunting

Is anyone familiar with the facts concerning the BOK (Bank of Oklahoma) Tower haunting in Tulsa, Oklahoma? The tower was constructed for the Williams Company in 1975...it was know as the Williams Tower back then. During its construction many of the workers heard an Indian (possibly a Shaman) chanting. After the building was finished security guards heard the same chanting and traced it to, if memory serves me, the 7th floor but found no one there. Because of the haunting the entire floor remained vacant for years. If you're familiar with this story PLEASE reply.
Thank you very much,

I went to theshadowlands.net and it wasn't listed. I would also like more info on this.

Thanks for checking, if I come up with anything I'll be sure to post it here.
Thanks again,

BUMP...just wanted to get this back on the top page for more consideration...Thanks All

I can't say I've ever heard of this either, where did you get your info from? I can't find any info on google. Does it have a nickname or anything (the place), that might bring up some better results?
