江崎グリコ
At around 9:00pm on 18 March 1984, two masked men armed with a pistol and rifle (later assumed to be toy guns) used a key stolen from the home next door to enter the home of Ezaki Glico president, Katsuhisa Ezaki. The home next door belonged to Katsuhisa's 70-year-old mother, Yoshie, and was located on the same property surrounded by a brick wall. The criminals had broken into her home and tied her up with a cut telephone line. They retrieved the key to her sons home which had a security system installed.
