Her little brother pleaded for his life, "I'm scared. I'm too young to die", before his sister stabbed him in the chest, and her boyfriend cut his throat.
When children murder, it's shocking. Even more shocking and unimaginable is when children murder their own parents. The youngest person ever charged with multiple counts of murder in Canada, then 12 year old Jasmine Richardson, and her then 23 year old boyfriend, Jeremy Steinke murdered not only her parents, Marc and Debra, but also her 8 year old brother Jacob in cold blood.
23 year old Jeremy Steinke, who was part of the goth crowd, and also proclaimed he was a 300 year old werewolf, purportedly met 12 year old Jasmine Richardson at a punk rock concert in 2006. Jasmine immediately became enamored with him, and with the goth lifestyle. They were in love; behind bars awaiting trial, Jeremy even proposed to Jasmine through jailhouse letters they exchanged. She accepted.
When Jasmine's family found out about her 23 year old werewolf boyfriend, they became furious, grounding her, and forbidding her from seeing him. For Jasmine, and Jeremy, this was reason enough for them to die.
On that fateful night, Steinke first attacked Jasmine's mother & father downstairs, stabbing them both to death. He then went upstairs, where Jasmine proceeded to stab her 8 year old brother Jacob in the chest, while he pled for his life. Jeremy then finished him off by slitting his throat. Jasmine testified in court that he was gurgling. She stated that the reason for their decision to kill her brother was that she thought it was cruel to leave him to live without his parents. Two hours after the death of her parents and brother, Jasmine and Jeremy were laughing and kissing at a nearby restaurant.
At trial, when she was asked why they murdered her parents and little brother, Jasmine said "I loved him so much. I thought it would bring us closer together".
Jasmine's sentence included credit for 18 months for time served, with 4 years to be spent in a psychiatric facility, followed by 4 and 1/2 years where she will be under conditional supervision in the community. As of the writing of this article in November, 2010, Jasmine has one year left to complete of the 4 years required by her sentence in a psychiatric facility, and will then be serving her time under conditional supervision in the community. In 2015, she will have completed her sentence, and be released at the age of 23.
Personally I think she should have been tried as an adult and spent half of her life in jail (I would've voted for life imprisonment though).
She's already basically been released (under conditional supervision) and will be completely free when she turns 23. From what she said in an interview she gave she obviously has almost no remorse, and doesn't even understand how wrong what she did was.
