Hector was found shot dead in his backyard. He was about a foot away from his back porch, lying next to his personal handgun. A bloody footprint was also found on the porch. Analysis of a bullet found nearby suggests that, based on the striation marks, the bullet that killed Hector came from a gun discarded in a nearby trash can. He apparently had a date that night with a woman named Isabel who left three voicemails on Hector’s phone that same day. Based on various evidence, the forensics team also created a digital rendering of the crime. In this story, what is an example of documentary evidence?
A.
the blood samples collected at the scene
B.
the voicemails from Isabel
C.
fingerprints collected off of the discarded gun
D.
the footprints found in the backyard soil
B. the voicemails from Isabel.
To determine which option radial fractures in a piece of glass look most like, we need to understand what radial fractures are.
Radial fractures are cracks that radiate outward from the point of impact on a piece of glass. These fractures occur when an object strikes the glass in a way that causes stress to propagate in a radial pattern.
Now, let's examine each option to identify which one resembles radial fractures the most:
A. Spokes of a wheel: This option accurately represents radial fractures. When a stone hits a piece of glass, for example, the cracks will emanate from the point of impact, resembling the spokes of a wheel. This is a likely match for radial fractures.
B. A circle: Radial fractures are not circular in shape. Unlike circular cracks that form a complete loop, radial fractures spread outwards.
C. A zig-zag: Zig-zag patterns typically occur in impact fractures where the force applied is not radiating from a central point. It does not accurately represent radial fractures.
D. A spiral: While spiral patterns can sometimes be observed in glass breakage, they are not characteristic of radial fractures. Spiral fractures develop when there is a twisting force applied to the glass, such as when a glass bottle is twisted.
Based on this analysis, the option that best represents radial fractures in a piece of glass is:
A. Spokes of a wheel.
