東京とうきょう八王子はちおうじスーパー強盗ごうとう殺人さつじん事件じけん たばこの吸すい殻がらから捜査そうさ

Three women were shot and killed in the robbery-murder case at the Nampei supermarket in Hachioji City, Tokyo, which will mark 30 years since the incident in 30 days. It has been learned from interviews with investigators that the Metropolitan Police Department collected more than 70 cigarette butts from the scene and surrounding area as evidence, and, through DNA analysis and other methods, identified the individuals who smoked all but two of them.

The identified individual is believed to be unrelated to the incident, but DNA has also been collected from the remaining two items, and the Metropolitan Police Department is continuing its investigation, as it cannot rule out the possibility that the perpetrator discarded them.

On July 30, 1995, at the office of the Nampei supermarket in Hachioji City, Tokyo, three people—two female high school students working part-time and a female part-time employee—were shot in the head and killed by an unknown assailant. As of the 30th, it has been 30 years since the incident, which remains unsolved.

In this case, no DNA that could be identified as belonging to the perpetrator has been collected, and this has become one of the factors making the investigation difficult.

The Metropolitan Police Department has collected more than 70 cigarette butts from the scene and its surroundings as evidence and is conducting investigations such as DNA analysis. Interviews with investigators have revealed that, except for two, they have identified the individuals who smoked them.

None of the identified individuals appear to be connected to the case, and it has been revealed that the lipstick-stained cigarette butt found in the ashtray at the office, which the special investigation headquarters had been seeking information about for many years, is believed to have been smoked by a former female employee who had already left the establishment at the time.

The two cigarette butts, whose smokers have not been identified, were found on the supermarket premises, and DNA has been collected from them. The Metropolitan Police Department is continuing its investigation, as it cannot rule out the possibility that the butts were discarded by the perpetrator, and is still seeking information related to the case.
