Abstract
Fingerprints and biological specimens such as blood are two crucial pieces of evidence to forensic science. There have been cases where blood prints have been left behind. Blood prints can be so faint that photography alone would not capture the print’s full detail. In situations like this, a forensic investigator has to decide which evidence is more important, processing a print or the detection of blood.
This research will determine a sequential process in recovering bloody prints by using Acetone Ninhydrin as a fingerprint enhancement devise and using Luminol or Fluorescein as a detector of blood. Results indicate that the best process in recovering both fingerprints and blood is by first applying Acetone Ninhydrin on the blood print followed by the application of Fluorescein. With these procedures, visible and detailed prints are produced on the blood print with the ability to detect blood afterward.
