Woman gets life in prison for killing father with insulin and brother with carbon monoxide

14 Comments

The Osaka District Court on Tuesday sentenced a 48-year-old woman to life in prison for killing her diabetic father and brother in 2018.

In the lay jury trial, which began in August, Akemi Adachi was accused of killing her father Tomio by giving him a large dose of insulin, and killing her then 40-year-old brother Masamitsu by making it look like he committed suicide by carbon monoxide poisoning at their home in Sakai city, Sankei Shimbun reported.

According to the ruling, Adachi, who was the president of a family construction company in Sakai, killed Masamitsu, who managed another company, at their parents' house in Naka Ward sometime between 2 p.m. and 6 p.m. on March 27, 2018. Prosecutors claimed that Adachi gave her brother sleeping pills.

Adachi called Masamitsu's wife and urged her to come to their parents' home because something had happened to Masamitsu. When Masamitsu's wife arrived just before 7:30 p.m., Adachi showed her a suicide note and said Masamitsu had shut himself in the toilet on the second floor. The toilet door had been sealed with an adhesive bond. When Masamitsu's wife and Adachi managed to open the door, they found Masamitsu’s body lying on the toilet floor. Traces of charcoal briquettes were found in the toilet.

Masamitsu was taken to hospital where his death was listed as a probable suicide due to carbon monoxide poisoning. However, traces of sleeping pills were found in his body after an autopsy. Furthermore, the empty adhesive bottle was not found inside the toilet, but in another room, along with a lighter. Police learned that Adachi had been prescribed sleeping pills which they believe she somehow gave to her brother via a spiked drink. A suicide note, purportedly from the victim, was found by his wife who said the writing did not look like Masamitsu’s. Police said they found the text of the note on Adachi's computer.

The Adachis' 67-year-old mother was also found collapsed at the house that day. She told police later that she blacked out after drinking a matcha latte made by Akemi.

The siblings' father, who had diabetes, had been brain dead due to low blood sugar since collapsing at the home in January 2018. Prosecutors claimed Akemi was responsible for his condition, too, by giving him a large dose of insulin as well as sleeping pills. He died of encephalopathy in hospital in June that year.

After her arrest, Adachi denied any wrongdoing and maintained that her brother took his own life out of remorse over killing their father. She told TV media before her arrest that she had nothing to gain from killing her brother. But prosecutors said that life insurance and a dispute over inheriting their father's business were motives for her actions.

Adachi remained silent throughout the trial.

She also faced allegations of slandering Masamitsu’s wife in April and May of 2018.

Killed two people for the purpose of inheriting money. The noose would have been far more appropriate for her. No loss.

RIP to the innocent father and son.

The amount of evidence pointing out to her is hard to miss even if the police were incompetent, obviously the criminal was really bad at covering her tracks. Life in prison seems appropriate punishment for killing her family.

Meanwhile elsewhere on JT today is an article about how a few death row prisoners are protesting the use of hanging as an inhumane way of carrying out the death penalty.

Not sure hanging should be abolished after reading this one.

What if you found out after the fact that one or more of those complaining was actually innocent, and was wrongly convicted?

On the news last night the judge couldn't hand down the death penalty demanded by prosecutors because

wait for it -

the intent of / motives for the murders is still not clear.

A par-for-the-course judiciary comment.

four years! No adhesive in the sealed toilet or a lighting device, and an autopsy showing excess amounts of drugs? She could of got away with the father, but totally plain stupid with the brother.

what did police do? Two dead bodies…four years?

Don't matter where you live, you don't have to look far for some pretty sad stuff, well, maybe the North Pole with Santa, but then again I'm sure those Elves can get into it when they want

Sounds like sleeping pills and charcoal briquettes sure works though. Could it be more humane?

@Rodney When have you know a criminal to be smart, they are only smart at what they THINK they are doing on short notice. Every crime leaves evidence and clues. I was taught that you can only tell the Truth one way no matter how many times you are asked a question about something you knew you didn't do if you tell the truth the story remains the same, on the other hand if you tell a lie he changes every time a person is asked the same question. In Akemi's case she she was just plain evil!
