Plymouth teen convicted in family murder plot gets 10-20 years in prison

Roksana Sikorski pleaded guilty to assault with intent to commit murder

DETROIT – Laurene Sikorski on Monday made a final plea for a judge to grant her daughter mercy when he sentenced her for her role in a plot to kill their family. 

Sikorski said her 17-year-old daughter was misled and used. 

"Nothing will benefit this child by sending her to jail. She made some poor choices that led her to this conviction," she said. 

Roksana Sikorski used a knife to cut her 12-year-old brother's neck and tried to stab her younger sister on Oct. 17, 2014, in their Plymouth Township home. According to Sikorski -- who was 15 at the time of the crimes -- and the prosecution, her 23-year-old then-boyfriend, Michael Rivera, was outside the house sending text messages to her on how to fatally stab the family members.

Sikorski and Rivera were both charged with assault with intent to murder and conspiracy to premeditated murder.

Sikorski was adopted from Poland by Laurene and Jeff Sikorski -- who also adopted her brother and sister. They have said she should not have been tried as an adult. 

"How will sentencing her as an adult help her? Is this justice?" Laurene Sikorski said. 

Sikorski pleaded guilty to one count of assault with intent to commit murder in exchange for other counts being dismissed. She was sentenced to 10 to 20 years in prison. 

“I would like to apologize to my family for not being the daughter they wished I could be. I promise I will get better, no matter what happens," Roksana Sikorski said. 

Judge James Callahan said he would request that she be kept at a juvenile facility until she is 18.

Text messages revealed teen's plot to stab family

As the evidence was laid out in court before the two were bound over for trial, Local 4 obtained some of the text messages the two exchanged the night of the attack. They're complete with instructions on how to slit a throat and peppered with emoticons.

"Babe I can't do it :( I need ur help," this text kicked off a stream of back-and-forth between Roksana Sikorski and her boyfriend, Michael Rivera.

According to investigators the two had hatched a scheme to kill her whole family. According to her texts, Sikorski was having a hard time going through with it.

"I feel like dad is waking. He's moving but snoring. Babe..?" Sikorski wrote.

Her boyfriend responded, "Baby im here just cut the throat quickly on both of them."

The texts are a volley between the duo. At one point Rivera sent Sikorski a picture of a neck to show where the artery is.

Sikorski texted, "Babe I can't f***ing do it. I'm too scared. I want u to do it.... :( Plzz baby plzz. He kept waking up."

Rivera responds, "If he sees.me tho babe there will be a struggle n cops will.come :/"

She pleads with him, "Babe no cops will come. I busted the phone lines. Plz babe :("
