The ParaFPI is a well organized and experienced research group. They are a local chapter of T.A.P.S., from Ghost Hunters of Sci Fi Channel fame. Check out their website.
In addition to photographic evidence some audio was recovered in the room while it was verified to be empty. One of the video cameras experienced a battery drain and shut off. While the camera was off, the digital audio recorder recorded the sound of what could be described as banging metal. Once the banging stopped, the battery drain ceased, and the video camera resumed recording. The rest of the data amounts to hours worth of video, audio, and photos, as well as temperature fluctuations and psychic sensitive readings. This data is still being processed and will be posted when it becomes available.
