What does a timeline represent?

• A. Series of crime in chronological order
• B. Information that can be gained from telephones and emails
• C. Development of case/event through time
• D. Text, email, radio, push to talk

Answer: (C)

A timeline represents the development of a case or event through time. It arranges events in chronological order, showing when each happened, how long between steps, and how events relate to one another. This helps investigators see progression, identify gaps, and plan next actions based on timing. The other ideas describe different things: a sequence of crimes is just a specific content focus, information from telephones and emails refers to sources of data rather than timing, and communication methods like text, email, or radio are channels, not the depiction of events over time.
