Ali David Somboly, 18, was a Munich resident who opened fire near a busy shopping mall on Friday evening, killing nine people and injured 27 others. He had set up a Facebook account under the impression of another indentity, in which he would lure his victims to the Mcdonald's restaurant in Munich.

As police raided Somboly's family apartment in an affluent suburb of Munich, they discovered extremist material linked to mass shootings, including the attack by Anders Behiring Breivik, the white supremacist who murdered 77 people in Norway in 2011, other mass murder documents relating to a gun attack on a school in Bavaria in 2009 in which 16 teenagers were killed as well as the book "Why kids kill: inside the mind of school shooters".

After following a raid on the apartment, prosecturors tried to interview the parents, however both were “too shocked” to provide any useful information. His brother have yet to spoke publicly about the massacre.

Four of the teenagers killed were friends of Somboly; Can Leyla, 14,  Selcuk Kilic, 15, Sabina Sulaj and Armela Segashi, both 14. A fifth member of the group was critically injured.

Dilan Demir described the scene on Facebook:

“I was close to the scene and was hiding with a friend. When it was very quiet we got up and saw five people. They looked dead, one of them was him [Selcuk] as his head lay on the table. So were his other two friends and the other two girls, were laying  on the floor.”

Classmates said Somboly had been bullied in school and had very little friends, while others described him as intelligent, quiet and shy but not very sporty. 

Neighbours had also described Sombly as “intelligent, quiet and shy,” an apparently normal 18-year-old.

Further footage emerged of him on the shopping centre’s rooftop car park, shouting “I am German” after a man challenged him.

That man was identified last night as Thomas Salbey, 57, who was sitting on the balcony of his tower block flat. 

 “I was drinking a beer after work when I heard the shots, first at McDonald’s. Bam bam bam – that’s how it sounded. Then I looked down from the balcony and saw him running along. As he reloaded his gun I got my beer bottle and threw it at him.”

The German-Iranian student lived comfortably in a fifth-floor apartment in the middle class Munich suburb of Maxvorstad with his parents; one of them a taxi driver and the other a department store worker.

Mostly home to immigrant families, the well-tended apartment block sits next to a luxury Maserati car dealership.

Germany Interior Minister Thomas de Maiziere, a member of Chancellor Angela Merkel's conservative Christian Democrats, told the Bild am Sonntag newspaper that he planned to review German gun laws after the attack, and seek improvements where needed.
