What is a transfer bloodstain?

Background: A transfer bloodstain is created when a wet, bloody surface comes in contact with a secondary surface. A recognizable image of all, or a portion, of the original surface may be observed in the pattern, as in the case of a bloody hand or footwear.

What is forward spatter?

Forward Spatter — Blood which travels in the same direction as the source of energy or force which caused the spatter. High Velocity Impact Spatter (HVIS) — A bloodstain pattern caused by a high velocity impact /force to a blood source such as that produced by gunshot or high speed machinery.

What is high velocity blood spatter?

High velocity blood spatter: The force of the blood hitting a surface for high velocity blood spatter is over 100 feet per second. This causes the pattern of the blood to be similar to a fine spray.

What are the four phases of impact?

When the blood falls from the source, the circular droplet essentially splashes out of itself to create the different patterns that are visible to the human eye. There are four phases of impact: contact and collapse, displacement, dispersion, and retraction.

What is a passive blood drop?

Passive drops are drops of blood that are formed under the influence of only gravity. This is often observed in incidents involving moving injured persons. Pool pattern. A pool pattern forms when blood has flowed in one place for some time, such as when a bleeding victim stayed there for a period of time.

What are the 3 types of blood stains?

Bloodstains are classified into three basic types: passive stains, transfer stains and projected or impact stains. Passive stains include drops, flows and pools, and typically result from gravity acting on an injured body.

What is a passive drop and what is its shape?

the force of gravity, the adhesive force, the force of energy. gravity and tension play a big role. 4. What is a “passive drop” and what is its shape? It is gravity that makes it flow more and more towards a collection point, the forces of surface tension and gravity will cause the large one to be retained.

What shape does blood have in flight?

Experiments with blood have shown that a drop of blood tends to form into a sphere in flight rather than the artistic teardrop shape. The formation of the sphere is a result of surface tension and cohesion that binds the molecules together.

What are 5 conditions that affect the shape of the blood stain?

What are conditions affecting the shape of a blood droplet? Size of the droplet, angle of impact, velocity at which the blood droplet left its origin, height, texture of the target surface.

How far can blood spatter travel?

Overall, the results indicated that the application of kinetic energy of between 1 and 5 J at a height of 1780 mm led to the blood droplets travelling a maximum horizontal distance of 5361 mm (and average maximum distance of 4981 mm).

How Does height affect blood spatter?

The height from which the blood falls will affect the size of the stain, with greater heights tending to result in larger bloodstains. This type of bloodstain is the result of a forceful impact between an object and wet blood, causing the blood to break into smaller droplets.

Is blood spatter evidence reliable?

Bloodstain-pattern analysis has been accepted as reliable evidence by appellate courts in one state after another with little or no examination of its scientific accuracy. Once one court ruled such testimony admissible, other states’ courts followed suit, often citing their predecessors’ decisions.

How do I become a blood spatter expert?

Steps to Become a Blood Spatter Analyst

  1. Earn a degree in natural science, such as biology, chemistry or forensic science.
  2. Gain certification through your state, if required.
  3. Apply for blood spatter analyst jobs.
  4. Pass a background check and drug test.
  5. Interview for the job and get hired in an entry-level position.

What does a blood spatter expert do?

Bloodstain pattern analysts, also known as blood spatter experts, collect and analyze physical evidence—specifically, blood. They are specialists in forensic science and crime scene investigation and examine the location and shape of blood drops, stains, puddles, and pools.

How long does it take for blood to dry out?

60 minutes

Is blood Class A evidence?

Blood type is considered to be class evidence. Although it may not specifically identify the suspect, explain how it still could be useful in helping to investigate a crime. Explain how the product rule can be used to determine whether two blood samples come from the same source.
