The crime scene investigator must remember that the location, distribution and appearance of bloodstains and spatters are probably not useful for interpreting and reconstructing the events that produced the bleeding. True False 39 Multiple Choice 303 points Tocalculate the angle of impact for blood spatter, one would use the equation SinA=W/L CosA=W/L TanA=W/L sinA=LM 20 Multiple Answer 303 points Blood spatter interpretation may uncover (choose all that apply) The direction from which blood originated The angle at which a blood droplet struck a surface The location or position of a victim at the time a bloody wound was inflicted Evidence leading to the arrest and conviction of the assallant

## Step1<br />The first question is a true/false question about the importance of the location, distribution, and appearance of bloodstains and spatters in crime scene investigations. The statement is false because these factors are indeed crucial in interpreting and reconstructing the events that led to the bleeding.<br /><br />## Step2<br />The second question is a multiple-choice question about the equation used to calculate the angle of impact for blood spatter. The correct equation is \(SinA=W/L\), where W is the width of the blood drop and L is the length of the blood drop.<br /><br />## Step3<br />The third question is a multiple-answer question about what can be uncovered through blood spatter interpretation. The correct answers are:<br />- The direction from which blood originated<br />- The angle at which a blood droplet struck a surface<br />- The location or position of a victim at the time a bloody wound was inflicted
