🔎 Fast Forensics: Case 5 – An intricate web of burner phones. A drugs line buried in plain sight.

The Serious Crime Unit has been tracking a suspected county lines operation stretching between Anton City and Scoby. Mobile signal data reveals communications between 15 burner phones, each playing a potential role in the network. One number is believed to be the central drugs line—used to organise supply drops and coordinate with customers.

Several phones show signs of being street-level dealers, while others may belong to buyers caught in the system. Your mission? Step into the role of a digital detective. Use mobile data patterns, call frequency, and set theory to uncover who’s running the line, who’s dealing, and who’s just caught in the crossfire. Maths meets mystery in this real-world investigation.
