Reinforcing the Pakistan link to the Mumbai terror attack,the FBI in a crucial testimony at the trial of the lone surviving gunman Ajmal Kasab said today the Global Positioning System (GPS) devices used by terrorists showed they had come from Karachi. Deposing in person before Special Judge M L Tahaliyani,a forensic expert of the US' Federal Bureau of Investigation,whose identity has been kept secret,said he had examined five GPS devices and a satellite phone which Mumbai police had recovered from the terrorists. GPS is a satellite-based navigation system. The forensic expert said that "Way Point" data retrieved from the GPS devices pointed to the route from Karachi to Mumbai and also positions between these two cities. Kasab,a Pakistani national,sat smiling all the while while the FBI official gave the evidence. The GPS devices were seized from sites targeted by the terrorists,including Taj Mahal and Oberoi hotels and M V Kuber vessel which they had hijacked to travel to Mumbai. The witness said that out of the five GPSes,two were not functioning because the battery was depleted and hence the data could not be retrieved from them. The other three GPS devices had clearly showed the route between these two cities. GPS devices automatically record the return trip,he said. The witness gave hard and soft copies of the data report submitted by him to the Mumbai police earlier. The expert said he had examined these devices on February 11 and completed the examination by February 18. He said Mumbai police had sent the devices in the sealed cover to the FBI. The witness said the data from the satellite phone showed two received calls and one missed call. Some had tried to contact but the satellite phone had not responded.
