Police have discovered (among other things) that the 16-year-old girl who was arrested last week on suspicion of trying to use poison to kill her mother was seen by her teachers as having a bright future as a chemist.

According to the principal of the girl’s high school, her expert knowledge of chemicals raised expectations among teachers that she would become a skilled chemist in the future.

In April, when a professor of Tokyo University’s agriculture faculty, among other graduates of the school, was invited to give a lecture about proteins at the school, the girl asked the professor many questions.

The teachers, who were impressed with her technical questions, said she was “really something.”

Powdered thallium, several types of chemicals, chemical books and specimens of dissected small animals were found in her room.

They also found out that after her teachers showed sympathy upon the hospitalization of her mother, the girl reported the incident on her blog with the words, “People are gullible.”

Police suspect that the girl became interested in chemicals due to her inability to interact with other people.
