The velocity classification system is a good way to classify impact patterns and to determine the kind of force that produced them. Caused by an impact of 100 feet per second.

. Blood spatter is categorized as impact spatter created when a force is applied to a liquid blood source or projection spatter caused by arterial spurting expirated spray or spatter cast off an object. Spatter patterns resulting from the interactions between a weapon suspect and victim.

An impact pattern consisting of large separate drops with diameters of 5 millimeters is. Is never used for descriptive purposes. Blood Spatter AnalysisImpact Patterns can help investigators determine the type of weapon used.

The velocity classification of an impact spatter pattern _____ the specific event that create the pattern. Human blood from one donor was used immediately upon collection to generate the bloodstain patterns used in this study. Low-velocity impact spatters are produced when blood drips by gravity and are easily discerned by smooth edges and round appearance.

At the crime scene the string method is used to find the ____ of an impact. The force associated with this type of spatter is greater than 25 ft per second HIGH FORCE VELOCITY IMPACT SPATTER. A total of 60 bloodstain patterns consisting of 30 impact spatter and 30 cast-off bloodstain patterns were created.

Specifically a medium velocity spatter pattern is usually attributed to blunt force injury while a high velocity pattern is typically attributed to a gunshot wound. Almost always gunshot but occasionally produced by contact with high-velocity machinery. The differentiation between these classifications however has been qualitative and.

In general as the impact velocity increases so does the velocity of the blood droplets projected from the. The stains generally measure 1 to 3millimeters. Can determine the kind of action that produced the pattern.

Cannot illuminate If murdered victim blood is found in the muzzle of a firearms it can be concluded that the gun _____________________ during the injury of the victim. Both a and b. 2 Medium-velocity spatter is often accompanied by cast-off blood since blunt-force attacks with an object are involved.

Impact spatter patterns consist of many drops radiating in direct lines from the origin of the blood to that stained surface. Dispersion of smaller drops of blood. Caused by an impact of 5 to 25 feet per second.

The characteristics of blood spatter depend on the speed at which the blood leaves the body and the type of force applied to the blood source. Describe the classifications of low- medium- and high-velocity impact. As an attempt to represent the variability expected of such patterns different methods of pattern creation were utilised.

The intersection of straight lines through the long axis of several individual bloodstains in an impact spatter pattern illustrates the _____ of the pattern. An impact pattern consisting of large separate drops with diameters of 5 millimeters is. Medium Velocity An external force of greater than 5 fps but less than 25 fps causes medium blood spatter.

The intersection of straight lines through the long axis of several individual bloodstains in an impact spatter pattern illustrates the. The velocity classification of an impact spatter pattern. DBoth A and B.

Impact spatter that measures less than 2mm in diameter The force necessary to produce this size spatter is greater than 100 ft per second This type of spatter is usually associated with. 1-2 Medium-velocity impact spatter consists of a combination of large and small drops that travel faster than low velocity spatters. False True or False.

The classification system of impact spatter is based on the size of drops resulting from the velocity of the blood drops produced and patterns can be classified as or impact spatter. Gunshot or other high velocity impacts produce a finemist pattern Beating with a weapon produces a lowervelocity pattern with castoffs Voids. Blows with a baseball bat hammer axe or similar instrument.

Blunt or sharp trauma often from knives hatchets clubs fists and arterial spurts can produce such stainsMost medium velocity stains found at crime and accident scenes form patterns. Can only be determined by a trained bloodstain pattern analyst. Area of convergence.

Cannot illuminate the specific events that produced pattern. 1-2Medium-velocity impact spatter consists of a combination of large and small drops that travel faster than low velocity spatters. These are small drops with diameters of 1 to 4 millimeters.

A common classification of impact spatter is based on the velocity of the impacting object on the bloody source. 2 Lastly high-impact velocity spatter occurs when high force is applied that sends the blood into a fine. The velocity classification of an impact spatter pattern can do what.
