While doctors were still fighting for the life of former Japanese Prime Minister Shinzo Abe, who later died of his injuries after being shot on Friday, police were already on their way to the 41-year-old bomber's apartment. Tetsuya Yamagami.

In his house, they found a whole arsenal of weapons similar to the one he used to commit the unprecedented crime.

Yamagami told police that Abe was affiliated with a group he hated.

Investigators have not revealed exactly which group it was about, as the investigation is still ongoing, but firmly asserted that it was not about political motives,

the nypost reports.

What is known is that Yamagami was a member of the Japanese Navy for three years when he was in his early twenties.

He told investigators that his mother went bankrupt after spending money to support a religious group, Japan's Mainichi Shimbun newspaper reported, citing a police source.

"My mother supported a religious group and I got angry," he was quoted as saying to the police.

The family then fell apart due to the mother's obsession with the group, and Yamagami believed that Abe was connected to this "specific organization", but did not describe its religious nature.

According to Kyodo News, Yamagami has accompanied Abe to several previous campaign speeches, including Thursday night when he was in the city of Okayama.

Police are still investigating whether the 41-year-old followed Abe with the aim of finding the right moment for the assassination, given that the former prime minister's participation in the rally in Nara was not confirmed until a few hours before the speech itself.
