Munich maniac Ali David Sonboly had 300 rounds of ammunition in his rucksack when he brutally murdered nine people during Friday's bloody massacre, it emerged today.
The 18-year-old loner, who police today described as being 'deranged', waged terror in the city as he gunned down three women and six men.
Police raided his parents' flat overnight and discovered the Iranian-German was reading documents about 'spree shootings' before he carried out the attack.
Sonboly used a Glock 17 semi-automatic handgun to kill the victims – aged 13 to 45 – and started his deadly rampage at a McDonald's restaurant in the city.
Officers also found he had a book, Why Kids Kill: Inside The Minds of School Shooters, in his bag when he started firing at helpless children who tried to run away.
Sonboly, who claimed he was bullied at school, did not have a licence for the weapon he used – which is a popular firearm used by law enforcement agencies worldwide.
