Police responded to an incident involving gunshots. when they arrived at the scene, they found two men arguing. one man named henry was inside the home, and the other man, ralph, was outside near a shed. two bullets went through the large living room window. the police did not recover the bullets. henry claimed that he was firing in self-defense and that ralph had fired the first shot, noted by a in the diagram below. in self-defense, henry shot the second bullet from inside the house, noted by letter b in the diagram. ralph claimed that he did not fire any guns and that the man in the house fired both bullets at him. as an expert in glass analysis, you have been called upon to determine what happened.

A man is shot in the head, and the bullet stops just outside the dura mater, and One of the bullets was said to have been fired from his gun.

1. Obtain the evidence envelopes labeled:

Suspect 1

Suspect 2

Crime Scene

2. Using Suspect #1 evidence bag, record your name, date, and time

on the Chain of Possession form.

3. Open the envelope labeled Suspect #1. Do not disturb the signatures on the evidence envelope. Open it from a different side.

4. Remove two pieces of glass fragments from suspect’s evidence bag

#1. Using a balance, determine the combined mass of both pieces.

Record the mass on Table 1. Leave the two pieces of glass on the

balance for further testing.

5. Reseal the evidence bag. Place a piece of tape over the opened

edge. Write your signature or initials across the interface of the tape

and the bag to maintain chain of custody. At this point, there should

be two taped areas on the bag, both containing signatures or initials

on top of the tape. Refer to proper chain of command described in

Chapter 2.

6. Set up a 250 mL beaker of water filled to overflowing. You may need

to add the last few drops with a dropper.

7. Position a clean, dry, 10 mL graduated cylinder to receive overflow

water. Several books may have to be placed under the beaker to

adjust the height of the beaker.

8. Slowly add your two glass fragments of glass Sample 1 into the beaker one at a time. Water will spill over into your graduated cylinder.

9. Measure the volume of water displaced by the addition of the two

glass fragments. This is determined by reading the amount of water

that has overflowed into the graduated cylinder.

10. Record the combined volume for the two glass fragments in Data

Table 1.

11. Calculate the density of the glass fragments from Suspect 1 evidence bag and record your answer on the data table.

12. Remove the two glass fragments from the beaker and handle as

described by your teacher.

13. Refill the beaker to just overflowing.

14. Repeat the process with glass from (Suspect) 2. Be sure to properly

open and reseal the evidence bag. Record your name, date, and time

on the Chain of Possession form. Record all information for Suspect

2 in the Data Table.

15. Repeat the process until you have recorded all the information for

the glass found on suspects 3 and 4, and the crime-scene evidence

envelope
