Cell phone triangulation nabs the 'serial bomber' suspect in Texas within a day
phone triangulation techniques revealed the Round Rock, TX hotel, where the suspect was hiding, and SWAT teams swooped in to enter in a car chase with him. According to the chief of Austin Police, Brian Manley, "as members of the Austin police department SWAT team approached the vehicle, the suspect detonated a bomb inside, knocking one of our SWAT officers back, and one of our SWAT officers fired at the suspect as well."
Later on, combining knowledge from the Google searches on his computer, and triangulation results from his cell phone, the authorities were able to pinpoint the exact location of the bomber, resulting in the SWAT raid on the hotel hideaway. While triangulation is based on cell phone towers that the phone connects to, and is not as precise as GPS coordinates, it has gotten pretty reliable with time, combining hybrid tracking techniques to find someone within a 100-feet radius with a great degree of certainty.
