From the ever-informative boing-boing.

In what authorities said was the first stalking case of its kind in Los Angeles County, Ara Gabrielyan, 32, was charged Tuesday with stalking and threatening over a six-month period to kill his former girlfriend and himself.

Gabrielyan -- who ran an Armenian CD and video specialty shop -- is suspected of using GPS technology to pinpoint her location so he could arrange apparent chance encounters at the bookstore, at the airport, even at her brother's grave site. (...)After the unidentified 35-year-old woman broke off their nearly two-year relationship, Gabrielyan would follow her by car, show up at her doorstep and call her 30 to 100 times a day, she told police.(...)

Gabrielyan had purchased a Nextel phone device that has a motion switch on it that turns itself on when it moves. As long as the device is on, it transmits a signal every minute to the GPS satellite, which in turn sends the location information to a computer. Gabrielyan, who paid for a service to send him the information, would then log on to a Web site to monitor her locations, police said. Police are investigating where Gabrielyan purchased the device and the tracking service.
