Blood Analysis: Spatter

What is blood spatter analysis?

• Blood spatter analysis involves analyzing the DNA found in blood samples.

• Blood spatter analysis is the study of different types of blood cells under a microscope.

• Blood spatter analysis is the process of determining the age of blood stains at a crime scene.

• Blood spatter analysis is the examination of bloodstain patterns to determine what happened at a crime scene.

What is blood spatter analysis?

• Blood spatter analysis is the study of different types of blood cells under a microscope.

• Blood spatter analysis is the process of determining the age of blood stains at a crime scene.

• Blood spatter analysis is the examination of bloodstain patterns to determine what happened at a crime scene.

What are the different types of blood spatter patterns?

• passive, transfer, projected, altered

• active

• drip

• splatter

How can the angle of impact be determined in blood spatter analysis?

• By measuring the distance between the blood droplets

• By analyzing the color of the blood droplets

• By counting the number of blood droplets

• By examining the shape and size of the blood droplets, as well as the directionality of the spatter pattern.

Explain the concept of satellite spatter in blood spatter analysis.

• Satellite spatter occurs when blood is exposed to extreme heat

• Satellite spatter in blood spatter analysis is the small droplets of blood that are distributed around a main bloodstain due to the impact or force applied to the blood source.

• Satellite spatter is only visible under ultraviolet light

• Satellite spatter is caused by the gravitational pull of the moon

What information can be obtained from the size of blood droplets in a crime scene?

• Blood droplet size can indicate the force and angle of impact, distance traveled, and type of weapon or object used.

• Blood droplet size can indicate the suspect's motive

• Blood droplet size can determine the suspect's height

• Blood droplet size can reveal the suspect's age

Discuss the significance of the shape of bloodstains in forensic investigations.

• The shape of bloodstains is irrelevant in forensic investigations

• Bloodstain shape can only determine the color of the blood

• The shape of bloodstains is significant in forensic investigations as it helps reconstruct the events of a crime scene by providing information on the angle, direction of impact, force applied, and distance from the origin of the blood source.

• Bloodstain shape does not provide any information about the crime scene

How is the point of origin of blood spatter determined?

• By analyzing the color of the blood spatter

• By measuring the distance between the blood droplets

• By counting the number of blood droplets

• By analyzing the directionality, size, shape, and distribution of the blood droplets.

What factors can affect the shape of blood spatter patterns?

• Type of surface, humidity level, blood type

• Angle of impact, velocity of blood droplets, surface texture, distance traveled

• Color of the blood, temperature of the room, time of day

• Distance from the victim, lighting conditions, presence of witnesses

Explain the difference between passive and active bloodstains.

• Passive bloodstains are caused by external force, while active bloodstains are caused by gravity.

• Passive bloodstains are caused by gravity, while active bloodstains are caused by external force.

• Passive bloodstains are bright red, while active bloodstains are dark red.

• Passive bloodstains are larger in size, while active bloodstains are smaller.
