Mieko Hattori, 70, from Nagoya, whose son, Yoshihiro, 16, was gunned down in Baton Rouge, Louisiana, in 1992, is working on a story for children that calls for stricter gun control measures in the United States.
She came up with the idea after meeting a girl who lost her friend in a school shooting in Florida in February.
"If citizens of Japan and the U.S. unite, they can change the gun society," Hattori says. Twenty-six years have passed since her son, who was studying in Louisiana as a high school student, died on Oct. 18, 1992. He was shot by a man after approaching the wrong house on his way to a Halloween party.
