Just like old serial killers who used to keep a journal for recording their macabre thoughts, a Japanese teen has been using her blog to keep track of the progress (or lack thereof) of her poisoned victims. First she started with small animals before moving on to her mother!

Following her idol, the british serial killer Graham Young (a.k.a Teacup Poisoner), she fed her victims slow-killing poison and watched them die. Being a bright chemistry student, she chose thalium for poisoning her mother and blogged about how it affected her system. She also photobloged her mother as she progressively slipping into coma (where she remains to this day).

Some of her blog entries:

“It’s a bright, sunny day today, and I administered a delivery of acetic thallium”

“Today mother has deteriorated. She has been complaining of a worsening pain in her leg and has now become immobile.”

“My mother will go to hospital tomorrow and nobody has yet found out what the cause is. To my regret, she is not covered by good insurance, so life will be a little difficult”

“I took a photo of her today as I did yesterday. My brother said I had a penetrating stare and that he was horrified.”

She was caught last October, and a court in Japan has sent her to a correctional home as she is still a 17 year old.

The most shocking thing in this episode is: “She did not hold a grudge against her mother - she just wanted to do an experiment.”

Deadly!
