German Federal Attorney General Peter Frank released a statement in Karlsruhe on Thursday regarding the deadly shootings in Hanau that left 11 dead, saying that the perpetrator had "confused thoughts and absurd conspiracy theories, but above all exhibiting a deeply racist ethos."

Peter Frank said that "nine persons with a migrant background were shot. Six further persons were injured, from those, one seriously," in the attack that took place late on Wednesday night.

He added that the police found a firearm next to the body of the suspect and his mother, who had been "evidently shot" at the perpetrator's home.

"On the homepage of the suspected perpetrator, he had video messages, and a kind of manifesto set up," said Frank.

The Federal Bureau of Investigation will lead the next stage of the investigation with the support of the Hesse State Police Department and will be looking at "whether there are or have been affiliates or supporters," both domestically and internationally.

A gunman opened fire outside one shisha bar in the city's Heumarkt district and drove off to a second location in the Kesselstadt district where he opened fire again, killing nine people and injuring several others late on Wednesday evening. The suspect was a 43-year-old German citizen from Hanau.

Together with his 72-year-old mother, he was found dead at his home in the early hours of Thursday morning.
