DETROIT – A Plymouth Township teen who was charged as an adult with allegedly plotting to kill her family pleaded guilty on Monday.
Prosecutors say 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 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.
Rivera went to trial last summer and was convicted. He was sentenced in August to life in prison.
Jury selection was supposed to begin Monday in Sikorski's trial, but she pleaded guilty to assault with intent to commit murder in exchange for other counts being dismissed.
Sikorski was adopted from Poland by Laurene and Jeff Sikorski -- who also adopted her brother and sister. They have maintained that Roksana was manipulated by Rivera and should not be tried as an adult.
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 :("
