'I Will Kill You All', Munich Gunman Warned

Munich killer David Ali Sonboly warned he would kill his classmates after a row at school, it has been reported.

The teenager told a 14-year-old girl living in his apartment block, "I will kill you all", after falling out with peers just weeks before the shooting.

Police are investigating whether Sonboly, 18, specifically targeted young victims as he rampaged through a McDonald's and the Olympia shopping centre armed with a Glock pistol and 300 rounds of ammunition.

Most of those killed were teenagers.

It was reported four of those who died were young friends sitting at the same table in the fast food restaurant.

They were two 14-year-old Kosovan girls, Armela Segashi and Sabina Sulaj, and their Turkish friends Can Leyla, 14 and Selcuk Kilic, 15.

Another victim named as 17-year-old Hussein Daitzik, of Greek origin, is reported to have been shot dead as he shielded his sister.

Guilliano Kollman, 18, is said to have died after being gunned down outside the McDonald's.

Naim Zabergja, a policeman of Kosovan heritage, visited the scene of the shooting clutching a picture of his 21-year-old son Dijamant, who was killed in the rampage.

Sevda Dag, a 45-year-old Turkish woman, was reportedly the oldest victim of the atrocity.

Meanwhile, Fadil Segashi, the uncle of Armela, said she was "an example to others".

He added: "She was only 14-years-old and she was a very good girl."

Authorities are checking reports that Sonboly felt bullied by his peers for several years, Interior Minister Thomas de Maiziere said.

Police said it appeared the teen hacked into a Facebook account and lured people to McDonald's with an offer of free food.

The posting had been sent from a young woman's account.

It urged people to arrive at the centre at 4pm, saying: "I'll give you something if you want, but not too expensive."

Apparently, one acquaintance of the teenage loner had warned young people to stay clear.

"This here is a fake account of one Ali Sonboly. Don't get your hopes up," wrote Lukas Dore.

He added: "The boy is psychologically disturbed and only wants attention."

It has also been reported Sonboly swapped his WhatsApp profile picture to that of mass murderer Anders Breivik.

Far-right extremist Breivik killed 77 people in Norway exactly five years before the Munich shootings.

Bavarian Interior Minister Joachim Herrmann said: "The fifth anniversary of the Breivik massacre ought to be considered as a motivation."

A search of the teenager's room has revealed he was obsessed with mass killings.

Police ruled out links with Islamic State.

During the search, investigators found a book about mass shootings by students.
