To obtain the luminescent images, absolute darkness was required and the camera exposure maintained for 3 minutes.
Niagara Falls Detective Lieutenant Nicholas Paonessa presented this report on one of the chemical agents to the International Association of Bloodstain Pattern Analysts: http://www.bluestar-forensic.com/pdf/en/Gettysburg_IABPAnews.pdf
It should be noted that the bone Paonessa referred to as being found on the Historic Daniel Lady Farm was later determined by a pathologist to be non-human.
Additional testing by the Niagara Falls Police on the floor of the parlor determined where a pile of blood-soaked rags had lain, fingers of a hand passed through a pool of blood and marks from the fingers of men who were propped against the wall.
Most surprising was evidence on the floor in an upstairs room of the upper torso of a body.
It’s no wonder that soon after the Civil War), Daniel and Rebecca Lady sold the farm and in 1867, moved their family lock, stock and-barrel to a newly-purchased farm several miles away near Arendtsville, leaving behind the daily reminders of death and suffering in their former home.
