EVP- This stands for electronic voice  phenomenon. These are dis-embodied voices that are caught on audio or video recorder microphones. When I say 
dis-embodied I am referring to voices that were not present to the human ear during the EVP sessions conducted. On later review they are heard and cannot be placed to the investigators in the room or area at the time. They are usually answering questions that are asked or interacting with investigators.
These EVP's were captured in a different Investigation where the confidentiality is upheld. This is an older district building here in Saskatoon. We were called in to investigate the claims of paranormal activity. Many of the claims we did de-bunk. But there was activity and it is an intelligent haunting.
