"For all the feet on the street chasing the suspects in the Boston Marathon bombing, a key break came when the victim who was carjacked and released by the Tsarnaev brothers on April 19 told the cops his Mercedes could be tracked with one quick call to Mercedes-Benz. They called and an hour later the police had the vehicle surrounded. A shootout ensued and when it was over, older brother Tamerlan Tsarnaev was dead, apparently either from gunshot wounds or being run over by his brother.
Boston police aren’t saying much. Mercedes-Benz provided a few details, since the general workings of its mbrace2 telematics system are well-known and described on the Mercedes-Benz USA website. Mercedes’ mbrace is a telematics application best-known for upgradable over the air (OTA) updates, without the need for a dealer visit."
