The man accused of fatally shooting former Prime Minister Shinzo Abe told investigators he researched how to make weapons on the video-sharing website YouTube, according to police sources.
The 41-year-old suspect Tetsuya Yamagami also told investigators he held a grudge against the Family Federation for World Peace and Unification -- more commonly known as the Unification Church -- because his mother went bankrupt after making large donations to the religious group.
According to the sources, Yamagami said he decided to target Abe around autumn last year because he thought the former prime minister was connected to the group.
