Sometimes the perpetrators are gangsters. Sometimes they are rather less accustomed to the criminal life. In one case, the ringleader of a middle-aged, female crime ring was said to be a 66-year-old woman.
"Gangsters, Grandmothers and Gold: Japan’s New Crime Wave" is from the June 14, 2017 Business section of The New York Times. It was written by Jonathan Soble and narrated by Kristi Burns.
