Mohammed Merah is seen yanking Myriam Monsenego by her hair — then firing a bullet into her head while he holds her.

Officials believe Merah strapped on a camera before each murder and posted the videos on jihadi Web sites, where he believed they would inspire other al Qaeda wannabes…

Before shooting one soldier, Merah proclaimed, “You kill my brothers; I kill you!” — a reference to France’s military presence in Afghanistan.
