| Summary: | The use of conventional fingerprint powder is the easiest and fastest method for fingerprint development. It is also the
workhorse at the crime scene and an important method used in the laboratory. The objective of this study was to examine
the difference in physical characteristics of the fingerprint after development using different fingerprint powders within
a six-week period. The study compared the number of positives identifications of each ‘minutiae’ after application of
black fingerprint powder and black magnetic fingerprint powder. The latent fingerprints from the donor were deposited
on clean microscope slides. The following prints were applied after thirty minutes. Similar rules of pressure and length
of deposition were made as much as possible. The slides were analyzed every week at similar intervals for six continuous
weeks with black fingerprint powder and black magnetic fingerprint powder with specific indicator. The black fingerprint
powder can be used for three weeks while black magnetic powder can up to fourth weeks. The results gave information
on an effective time frame using both fingerprint powders for fingerprint development. |
