Final answer:
DNA evidence can provide an investigator with information regarding the suspect's identity, but not their location or motive.
Step-by-step explanation:
DNA evidence can provide an investigator with information regarding the suspect's identity, but not their location or motive. Therefore, option 1) Suspect's identity is correct, while options 2) Suspect's location and 3) Suspect's motive are not.
DNA analysis can help identify a suspect by comparing their DNA to DNA found at a crime scene or on a specific item. This can be done through techniques like DNA fingerprinting or DNA sequencing. By comparing the DNA profiles, investigators can determine the likelihood of the suspect's involvement in the crime.
