MUNICH (AP) — The teenager behind Friday’s deadly shooting rampage at a Munich mall had planned his attack for a year and chose his victims at random, investigators said Sunday.
Bavarian investigator Robert Heimberger said the shooter, an 18-year-old German-Iranian identified only as David S. but named in other press reports as David Ali Sonboly, visited the site of a previous school shooting in the German town of Winnenden and took photographs last year, then set about planning the attack in which he killed nine and wounded some three dozen others before taking his own life.
“He had been planning this crime since last summer,” Heimberger told reporters.
He said there were “many more terabytes” of information to evaluate, and that the teenager’s brother and parents were still not emotionally up to being interrogated by police.
There is so far no evidence that he knew any of his victims, or that there was any political motivation behind the attack, said Thomas Steinkraus-Koch, a spokesman for the Munich prosecutors’ office.
Sonboly received both inpatient and outpatient psychiatric treatment last year to help him deal with “fears of contact with others,” Steinkraus-Koch added. He said medication had been found at his home but that investigators needed to talk with his family to determine whether he had been taking it.
Investigators said they saw an “obvious link” between the killings and white supremacist Anders Breivik’s massacre of 77 people in Norway exactly five years earlier.
In the aftermath of the attack, Bavaria’s top security official urged a constitutional change to allow the country’s military to be able to be deployed in support of police during attacks.
Because of the excesses of the Nazi era, Germany’s post-war constitution only allows the military, known as the Bundeswehr, to be deployed domestically in cases of national emergency.
But state Interior Minister Joachim Herrmann told Welt am Sonntag newspaper that the regulations are now obsolete and that Germans have a “right to safety.”
“We have an absolutely stable democracy in our country,” he said. “It would be completely incomprehensible … if we had a terrorist situation like Brussels in Frankfurt, Stuttgart or Munich and we were not permitted to call in the well-trained forces of the Bundeswehr, even though they stand ready.”
Munich deployed some 2,300 police officers to lock down the city Friday night, calling in elite SWAT teams from around the country and neighboring Austria, during the shooting at the mall and a nearby McDonald’s restaurant.
It was the second attack targeting victims apparently at random in less than a week in Bavaria. On Monday, a 17-year-old Afghan asylum-seeker wounded five people in an ax-and-knife rampage near Wuerzburg, for which the Islamic State group has claimed responsibility.
In the fog of the Friday attack, witnesses had reported as many as three shooters, and the city’s public transit was completely shut down for hours as authorities searched the streets.
Herrmann said that in other European nations it goes without saying that the military is brought in to aid during “extreme domestic threats” and he said Bavaria would urge changes so that it is allowed in Germany as well.
Weapons are strictly controlled in Germany and police are still trying to determine exactly how the shooter obtained the Glock 17 used in the attack.
Heimberger said it appears “very likely” that the suspect purchased the weapon online through the so-called “darknet.” It was a pistol that had been rendered unusable and sold as a prop, then was restored to a fully functioning state.
Its serial numbers were filed off and Sonboly had no permit to purchase weapons, authorities have said.
Even though it was an illegal weapon, Vice Chancellor Sigmar Gabriel suggested Sunday that even stricter controls on legal access are needed, telling the Funke Media Group that “we need to do everything further possible to curb the access to deadly weapons and strictly control them.”
“How can it be that an unstable, or possibly even mentally ill 18-year-old comes into possession of a firearm?” he asked.
Germany’s top security official, Interior Minister Thomas de Maiziere, said, however, that Germany’s weapons regulations are already “very strict” and appropriate.
He said authorities first need to determine where the shooter got the weapon from.
“We’ll then have to look very carefully at whether there then needs to be a possibility for additional legal action,” he said.
