Shinzo Abe's crazed killer believed the former Prime Minister was tied to a religious group which allegedly bankrupted his mum.
Gunman Tetsuya Yamagami, 41, has reportedly admitted he intended to kill 67-year-old Mr Abe in the shooting.
Yamagami was arrested after he shot the politician with a homemade gun as he delivered a campaign speech in the city of Nara.
