The investigation late last year into a string of mysterious deaths in Hyogo Prefecture captivated the nation, with probably the most intriguing (and grim) aspect of the case involving the continued discovery of multiple corpses.
Such a means of disposal might lead many to suspect the involvement of organized crime. In fact, the lead suspect, Miyoko Sumida, 64, was a mere novice who allegedly enlisted the help of multiple members of her family and acquaintances in the killings. She eventually committed suicide in her detention cell in December.
The magazine enlists the expert testimony of an upper member of a gang affiliated with a major criminal syndicate.
“We don’t pack bodies in drums and dump them at sea,” says the yakuza member. “That’s the work of amateurs.”
One reason is that the flesh decays and releases gas. “The gas is a powerful enough to crack concrete,” says the gangster. “So a medical coroner can determine that a body is inside the concrete.”
As to burying bodies under a home, the yakuza says that will create the same problem. “Digging a hole and covering a body with concrete is amateur stuff,” the gangster says. “Gas from the decomposing body will crack the concrete and it’ll be obvious what’s underneath.”
Today’s gangsters toss bodies into a mix of coal tar and gravel heated to 3,000 degrees centigrade. The gangster says that once the asphalt is spread out, for use in road pavement work, any sign of human life, including DNA, disappears entirely: “The high temperature incinerates the bones and flesh entirely.”
There are costs involved. It is necessary to develop a relationship with personnel at the asphalt plant, which will charge one million yen for the operation. As well, a contract will need to be taken out with a middleman — for a Chinese national the going rate is 200,000 yen.
“To kill someone is simple,” the gangster says. “But the sign of a real pro is in the disposal process.”
The purchase of a car used for pet cremations is also an option, says the gangster. The current market price is 1.5 million yen. “The maximum length of the material to be inserted is 40 centimeters so the body will need to be cut up,” he says. “All it takes is 90 minutes.” (A.T.)
