Besides the crime scene, there are several other possible sources of physical evidence.

Full Answer Section

• Victim's Person/Residence/Vehicle: The victim's body, home, or vehicle can also hold valuable clues.

  • Example: DNA from the suspect left on the victim's body (e.g., skin cells, saliva). Trace evidence from the suspect (e.g., hair, fibers) transferred to the victim's clothing or belongings. Physical evidence of an assault (e.g., bruises, wounds). The victim's personal belongings that might have been stolen by the suspect. In cases of vehicular crimes, the victim's car itself becomes part of the crime scene and needs to be processed for evidence.

• Digital Devices (Cell Phones, Computers, etc.): In today's digital age, electronic devices are a rich source of evidence.

  • Example: Cell phone records can reveal communication between the suspect and victim, location data, and even photos or videos related to the crime. Computer hard drives can contain emails, documents, or internet search history that provides motive or links the suspect to the crime. Social media accounts can be used to establish relationships, timelines, or even admissions of guilt. Deleted files can often be recovered using forensic techniques.

Beyond the crime scene itself, several other locations or sources can yield crucial physical evidence in criminal investigations. Here are three examples:

1. Suspect's Residence/Vehicle: A suspect's home or car can be a treasure trove of physical evidence. Investigators might find:

   • Example: Fibers or hair matching those found at the crime scene, linking the suspect to the location. Bloodstains (visible or latent) that could match the victim or contain the suspect's own DNA if they were injured during the crime. Tools or weapons used in the crime. Documents or electronic devices containing incriminating information. Clothing worn during the commission of the crime.
