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.
You'd need 3mm holes to block a cell signal. Making that with chicken wire is difficult.
But the sophistication, as I read it, is not technical but understanding how he could be tracked from a technical viewpoint and taking measures to subvert them.
