An anonymous reader writes: In the early morning hours of September 13, 2008, a woman notified the Tallahassee Police Department (TPD) that she had been raped and that her purse, containing her mobile phone, had been stolen. Within 24 hours, the Florida capital’s police had contacted Verizon and obtained real-time ping information, which gave the police a “general area” where they might find the phone and thus, hopefully, the perpetrator of the crime. But that general area still covered plenty of ground—where exactly was the phone? ...
After learning the phone's general location, Tallahassee cops deployed a vehicle-mounted stingray and cruised the streets. Verizon had already provided them with the phone's unique IMSI identifier, which told the stingray exactly which handset to track. (“Stingray” is a trademarked product manufactured by Florida-based Harris Corporation, though it has since come to be used as a generic term, like Xerox or Kleenex.) ...
Eventually, Corbitt and his colleagues detected the phone inside apartment 251, the residence of a woman who was also hosting her boyfriend, the suspect James Thomas. Officers knocked on the door; when it opened, one inserted his foot in the opening to keep it from being closed again. Police then conducted a "protective sweep" of the apartment and waited while a search warrant was obtained. ...
This newly released transcript (PDF) provides what is likely the first-ever verbatim account of how stingrays are used in actual police operations. And it shows that stingrays are so accurate, they can pinpoint the very room in which a phone is located.
