A legal fight over the government's use of a secret surveillance tool has provided new insight into how the controversial tool works and the extent to which Verizon Wireless aided federal agents in using it to track a suspect.
Court documents in a case involving accused identity thief Daniel David Rigmaiden describe how the wireless provider reached out remotely to reprogram an air card the suspect was using in order to make it communicate with the government's surveillance tool so that he could be located.
Rigmaiden, who is accused of being the ringleader of a $4 million tax fraud operation, asserts in court documents that in July 2008 Verizon surreptitiously reprogrammed his air card to make it respond to incoming voice calls from the FBI and also reconfigured it so that it would connect to a fake cell site, or stingray, that the FBI was using to track his location.
