Digital forensics experts track phone movements using cell site location information

Digital forensics experts use Cell Site Location Information (CSLI) from Call Detail Records (CDRs) to track past phone movements. CSLI logs interactions with cell towers, creating a timeline of a phone's location during calls, texts, and data usage. This information helps investigators verify alibis and build timelines in criminal and civil cases. For example, if a suspect claims to be at home, CSLI can show if their phone connected to towers near a crime scene, contradicting their statement. While CSLI is a valuable tool, it has limitations and is often used alongside other evidence, such as surveillance footage and witness accounts. Together, these sources help create a clearer picture of events.
