Prosecutors highlighted “about $10,000 — $8,000 in U.S. dollars and then $2,000 in foreign currency that was found on his person,” CNN correspondent Danny Freeman said following the court hearing.
“Also they said that he had a Faraday bag,” which blocks cell signals, a move that prosecutors alleged marked “an indication of criminal sophistication and reason they should hold him on bail,” Freeman continued.
After prosecutors made the claims, Mangione said he would like to “correct two things.”
“I don’t know where any of that money came from — I’m not sure if it was planted. And also, that bag was waterproof, so I don’t know about criminal sophistication,” the suspect said in a statement that suggested police framed him.
Even with location off, couldn't the cell provider track him using his phone connections by triangulating the latency between at least three cell towers? They may not get a location as precise as GPS, but they'd be close enough. I guess there could be an app that creates false latency in order to throw off cell providers, but that seems extreme and possibly illegal. Unless configured, it would also give odd locations to the cell provider which may trigger further investigation. "John Doe was in Long Island 3 minutes ago, and now they're in Newark. That's unusual." To go completely off of the grid, a person would have to not log into anything and also have no cell phone. They'd have to go back in time to the early 90s using maps, notebooks, and public phones.
