There is no stipulated number of points of similarity that is statistically supported for the identification of a fingerprint, in existence.

Enhancing Crime Scene Capabilities with Quadcopter Systems

When working an outdoor crime scene, law enforcement agencies face several concerns. Foremost among those concerns is the need to map or reconstruct a scene; to create an image of the scene for later use; and to mark each and every piece of evidence in a meticulous way. All of this must be done quickly, since in many cases there is an urgency to re-open main traffic routes or public areas.

And after leaving the scene, all of that documentation needs to be easily shared with non-agency parties such as officers of the court and service providers, such as insurance agencies.

Photography of Luminol and Bluestar Enhanced Bloodstains

Investigators have used Luminol to detect latent bloodstains for more than three decades. Luminol is a chemical reagent that reacts to hemoglobin in blood, causing chemiluminescence resembling a blue or violet glow. Bluestar Forensic, a more recent variation, uses a similar chemical reaction to create chemiluminescence. Both have been widely tested and studied and are generally known as the preferred search reagents when the objective is to locate trace amounts of blood. Researchers and practitioners have illustrated the following benefits:
