Question

question 1 even though fingerprints typically remain unchanged throughout a person’s life, some injuries can wear away fingerprints. what might be some ways in which a person could lose or alter their fingerprint? question 2 explain how interaction with specific apps on a smartphone can be used to trace the movements of a victim or a potential suspect. how might this evidence be used to help prove a suspect’s guilt?

Explanation:

For Question 1, deep - layer skin injuries like severe burns, chemical burns, or repeated friction from certain industrial work can damage the dermal papillae which form fingerprints. For Question 2, many apps collect location data. If a suspect's phone has an app that records location (e.g., fitness or navigation apps), the time - stamped location data can place the suspect at the crime scene or show movement patterns related to the crime. This can be used as circumstantial evidence in court to build a case against the suspect.
