Eight-year-old Myriam Monsonego clutched her satchel as the killer chased her through the school gates and into the courtyard. He pulled her towards him by her hair and raised a gun to shoot her. The video footage appears to show that, at that moment, his gun jammed. But determined to carry out his killing spree, he kept hold of the girl, changed weapons from what police identified as a 9-mm pistol to a .45 calibre weapon, and delivered a shot to her temple at point blank range. He then turned, calmly walked out the school gates, mounted a powerful Yamaha scooter and sped away.
