A 17-year-old girl in Detroit, Michigan cried in court on Monday as she was sentenced to 10 to 20 years behind bars for conspiring to kill her entire family with her adult boyfriend.
Roksana Sikorski was just 15 years old in October 2014, when she woke up in the middle of the night and sliced her little brother's throat in a failed attempt to off her parents and two siblings.
Before the judge read her sentence on Monday, Sikorski's mother addressed the court and pleaded for mercy for her adopted daughter.
'She's in desperate need of continued psychological help,' Laurene Sikorski said. 'She is still fragile, and an adult prison would shatter her delicate world. How will sentencing her as an adult help her? Is this justice?'

Roksana Sikorski, 17, was sentenced to 10 to 20 years in prison on Monday, for conspiring to kill her four family members
Roksana broke down in tears on Monday when she learned her fate. She apologized to her parents 'for not being the daughter they wished I would be'
Her adopted father Jeffrey added that he was 'disgusted' with how the trial unfolded and that he worries with how she will fare in prison.
'She’s vulnerable. She’s young,' Mr Sikorski said.
Roksana was four years old when the Sikorskis adopted her and her two siblings from Poland.
Due to abuse she suffered in early childhood, Roksana was diagnosed with reactive attachment disorder - a mental illness where children are unable to form an emotional attachment with their primary caregivers.
The teen appeared genuinely sorry in court on Monday as she apologized to her parents 'for not being the daughter they wished I would be'.

'I promise that I will get better, no matter what happens,' Roksana said through tears.
Despite the protestations of her parents, the judge nonetheless sentenced Roksana to 10 to 20 years behind bars.
The teen took a plea deal back in February, agreeing to plead guilty to one count of assault with intent to murder in exchange for six other felony charges getting dropped.
Meanwhile, the boyfriend who encouraged Roksana to kill her whole family is serving a life sentence for the crime, after being found guilty on all seven counts.
Michael Rivera, now 24, allegedly convinced Roksana to join the plot shortly after he was arrested for having illegal sex with the underage girl.

Rivera was 22 at the time and thought having Roksana kill her entire family would stop the prosecution of the rape case against him.
The young man apparently texted Roksana detailed instructions on how to kill her parents and siblings the night of the incident.
'Baby im here im here just cut the throat quickly on both of them ... Just stab there necks baby at the artery,' one of the text messages from Rivera reads.
