From News of the Weird:
Albuquerque, N.M., police arrested Amadeo Salguero, 21, in May and charged him with carjacking three people at gunpoint and making off with their Acura, which, according to a detective, contained one of the best stereo systems in town. Salguero was busted after he later called one of the victims and asked (according to police), "I don't want there to be hard feelings, but, hey, how do you hook up your amp?" The call was traced to the cell phone of Salguero, who happens to live across the street from the scene of the carjacking. [Albuquerque Journal, 5-17-02]
