A woman near at a gym near Philadelphia suddenly discovered her car keys and her top-of-the-line 2001 Lexus missing. Four hours later, she and her husband found it at a nearby apartment complex. Lexus used a Global Positioning System device to track it down, says the Philadelphia Inquirer. The company located the car through a GPS-antenna transceiver in the back of the vehicle. The antenna sends a signal to a satellite in space, which told Lexus where the car was.
Twenty-four hours later, an 18-year-old Philadelphian who had been identified on surveillance cameras showed up at the gym for his workout and was arrested for auto theft.
“It’s a shame those things [GPS] are only available in luxury cars,” said Lower Southampton, Pa., police officer Eric Landamia, who said this was the first time the department was assisted by a GPS unit. “The bad guys can’t make it 10 feet.”
