Assume that you are a crime scene investigator and have been called to a crime scene to investigate the murder of a homemaker. U
pon arrival at the crime scene, you find glass fragments on the driveway of the victim’s house. You find the body of the victim lying on the carpet in the living room. A crystal vase lies in pieces near the body. There is no fingerprint evidence on the vase. A neighbor confirmed that he saw a man driving a blue van up the driveway the previous night. He believed the vehicle was an older model from the 1980s. I will give you the brainiest
Briefly describe the steps you would take to solve the case by using the glass evidence found at the crime scene.
This type of determination compares a known sample to a glass fragment to see if the two samples came from the same source.
Glass can be made from a variety of different materials that differ from batch to batch. The presence of the different materials in the glass makes it easier to distinguish one sample from another. Also, the properties of glass can vary depending upon the temperature the glass is exposed to during manufacturing. Basic properties, such as color, thickness, and curvature, can also help to identify different samples of glass just by looking at them. Optical properties, such as refractive index (RI), are defined by various manufacturing methods. RI is the manner in which light passes through the glass. This can be measured easily even on small fragments of glass. These properties help to indicate that two samples of glass could be from the same source.
