3D Laser Scanning Techniques for the Crime Scene Investigator

THERE ARE SOME SITUATIONS that require high-detail scanning. When scanning point of impact, trajectory rods, bloodstain patterns, or anything else that requires very high detail, scan your scene on the determined scene settings and then obtain high-resolution and high-quality scans at a setting of at least 1/4 resolution and 4x quality (if color is applied). Alternatively, after a scan is complete, you can add clusters that include the high-detail area. This reduces your horizontal and vertical angles to allow a high-resolution scan of the specified item within a shorter period of time.

Lifting Latent Fingerprints from Difficult Surfaces

ALMOST ANYONE can find, process, and lift a latent print that happens to be in a logical and obvious place like a door handle, a beer can, or a butcher knife. But sometimes, a latent print is not just sitting there in a logical and obvious place. Sometimes, you have to use your imagination to find the print and your skills to lift it.
