Bloodstain Pattern Analysis || with 100% Verified Solutions.

The study of the shape, size, distribution, and location of bloodstains. correct answers Bloodstain Pattern Analysis (BPA) Tells us about the HOW as opposed to the WHO correct answers What does bloodstain pattern analysis tell us? Impact location(s), position of blood source, movement of people and objects during and after bloodshed, sequence of events correct answers What information can BPA provide? Passive, transfer, spatter correct answers What are the 3 primary classifications of bloodstain patterns? Created or formed by force of gravity alone correct answers Passive bloodstain patterns Result from contact between a blood-bearing surface and another surface correct answers Transfer bloodstain patterns Result from a blood drop dispersed through air due to an external force applied to a source of blood correct answers Spatter bloodstain patterns Satellite spatter: small droplets of blood distributed around a main droplet or pool of blood correct answers What is being shown in this picture? Define it. Type of passive pattern. Single blood drops which are relatively round with limited satellite spatter. correct answers Drip stain Type of passive pattern. Blood drips into another drop of liquid (possibly also blood). correct answers Drip pattern Type of passive pattern. Blood drips off of a moving object or person onto the ground. Outlines direction of movement. correct answers Drip-trail pattern Type of passive pattern. Blood falls into a larger volume of blood. More satellite spatters. correct answers Splash pattern Type of passive pattern. Indicates there was an accumulation of a large volume of blood on a substrate. No satellite spatter. correct answers Pool pattern Type of passive pattern. Forms by gravity causing movement of blood from the initial droplet on a vertical surface. Has long, narrow patterns. correct answers Flow pattern Type of passive pattern. Indicates that there was an accumulation of blood on a porous substrate (ex. clothing, bedding); blood has absorbed into the substrate's matrix. correct answers Saturation pattern
