The Federal Public Prosecutor’s Office of Frankfurt extended the warrant and investigation into Philipp K. for “negligent homicide in nine cases.” Philipp K. was initially arrested for violating weapon laws in Germany, but further investigation has been initiated
Investigators arrested the vender nearly a month after the shooting, posed as undercover buyers. He admitted selling David Ali Sonboly a Glock 17 and several rounds of ammunition during communication with undercover officers. Officials believed the 31-year-old arms dealer had no knowledge of what his customers would do with the guns.
Georg Ungefuk, a spokesperson for the Federal Public Prosecutor’s Office of Frankfurt, told a local newspaper:
The arrest warrant was initially issued only because of the violation of the arms laws. The further investigation of the secured communication from the supposed arms dealer on the Darknet – the anonymous area of the Internet – however, showed indications of negligence. There was no evidence that the 31-year-old Marburger knew what the amok gunman had in mind.
This has now changed, according to Ungefuk. K “could have known that his customer with weapons might kill people,” he said.
