• Special Agent Nicholas Donnelly : So, we've been tracking this man for ten months. Every time we get close, he slips right out from under us, as if he has some guardian angel. All I've looked for since then is a lead, any lead, and then I realized, the phone. He's in constant communication with his handlers.

  Detective Joss Carter : I thought of that. Cross-checked crime scenes he was reported at with cell tower logs of IMEIs. Came up with nothing.

  Special Agent Nicholas Donnelly : Exactly. Nothing. Our engineers at Quantico analyzed the cell tower traffic from that night he gave us the slip downtown. Under the wireless and radio noise, they found short bursts of a cloned IMEI with a unique signature. I tasked an FBI computer cluster to search for that signature. 24 hours ago, the cluster came online. It spotted another burst of cloned imeis at the exact time and location of the robbery. It's him. I've got SWAT teams standing by. If he uses that phone, we'll have him.
