Police at the home of Tetsuya Yamagami, accused of killing Abe, seized self-made weapons and tools used to make weapons.
According to the British newspaper “Daily Mail”, Japanese police seized a 9-barrel handgun, remotely controlled via a mobile phone, from Yamagami’s home.
Police said Abe was killed with a hand-made weapon made from purchased parts online by Yamagami.
Investigations indicated that Yamagami was considering assassinating Abe with bombs before he changed his mind and resorted to a weapon he had made himself.
Yamagami said in the investigation that he made weapons out of steel tubes that he stuck together in multi-barreled pistols.
