🔎 Fast Forensics: Case 4 – When a woman’s handbag is snatched in broad daylight, two local witnesses point the finger at Jack Simmons — a young man with a bit of a history. But Jack swears he was across town at the time, grabbing a drink at The Oak Leaf Pub. With emotions high and the CCTV footage too blurry to confirm anything, it’s up to you to dig into the evidence and uncover the truth. Was Jack running from the scene… or just in the wrong place at the wrong time?

Jack insists he was across town, enjoying a quiet drink at a local pub. But the timing’s tight, the footage is unclear, and the witness reports don’t quite align. The police aren’t convinced. And neither should you. Use speed and distance calculations to test his alibi, apply probability to evaluate witness reliability, and use coordinate geometry to triangulate Jack’s phone location from mast data. This case blends mobile technology, real-world crime, and core algebra skills — ideal for students who enjoy logic-driven problem solving with a strong narrative twist.
