  What will be an ideal response?

Question 2

Define the terms area of convergence and area of origin and explain what each reveals to an investigator.

Answer to Question 1

Answer should include points such as the following:
The drawback effect occurs when back spatter strikes the gunman and enters the gun muzzle. Fine impact spatter from a gunshot also travels a relatively short distance before falling from gravity. Blood within the muzzle of a gun helps an investigator place this suspect handgun in relatively close proximity to the inflicted gunshot wound.

Answer to Question 2

Answer should include points such as the following:
The area of convergence is the point on a two-dimensional plane from which the drops originated. It tells the investigator approximately where the source of blood (i.e., the victim) was located at the time of impact.
The area of origin of a bloodstain pattern is the point in a three-dimensional space from which the drops of an impact spatter pattern originated. This can show the position of the victim or suspect in space when the stain-producing event took place.
