Tsutomu Miyazaki was a very disturbed individual that targeted little girls, mutilated their bodies, raped, and murdered them.
In 1984, at the age of 21, Miyazaki began to watch child pornography.
Between August 1988 and June 1989, Miyazaki mutilated and killed four girls between the ages of 4 and 7. On top of that, he even engaged in sexual acts with the corpses.
In time, authorities caught on to Miyazaki’s acts. A search of Miyazaki’s two room bungalow turned up a collection of 5,673 videotapes, some containing anime and slasher films (later used as reasoning for his crimes).
His trials began on March 30th, 1990. After court trials began, Miyazaki’s father refused to pay for his son’s legal defense and eventually committed suicide in 1994.
On June 17th, 2008, Miyazaki was hanged.
