A Plymouth Township teen charged with plotting with her boyfriend to kill her family pleaded guilty to assault with intent to murder Monday.

Roksana Sikorski, 16, could spend 10-20 years behind bars when she is sentenced March 28 — a week after her 17th birthday — before Wayne Circuit Judge James Callahan.

The plea was made Monday, the first day of the teen’s trial on several charges in connection with the 2014 incident, according to court records. Sikorski’s co-defendant and boyfriend, Michael Angelo Rivera, 24, was convicted and sentenced in August to life in prison. He’s serving time at the St. Louis correctional facility in mid-Michigan.

A gag order has been placed on the case. Efforts to reach Sikorski's attorney and that of her imprisoned boyfriend were unsuccessful.

Sikorski, who was charged as an adult along with Rivera, had faced trial on a string of charges including conspiracy, assault with a dangerous weapon, felony assault and using a computer to commit a crime.

Sikorski, 15 at the time of the crime, was accused of slashing her 12-year-old brother’s neck about 2 a.m. at the family’s home in the upscale Heather Hills subdivision while Rivera stood outside the home. Her brother has since recovered.

According to a police report obtained by The Detroit News, Sikorski was worried whether the knife she allegedly used would do the job.

Sikorski texted her boyfriend “is this sharp enough?” referring to the 6-8 inch filet knife police say the girl used to stab her brother, according to the report filed by a Wayne County Law Enforcement Task Force,

Sikorski’s younger sister, then 11, screamed that her brother had been stabbed saying, “Lucas just got stabbed by Roxy,” according to the police report filed Oct. 17, 2014.

Sikorski made a confession to police about the crime, but it was suppressed after Callahan ruled on a motion by the defense not to allow it into the trial. The Michigan Court of Appeals affirmed Callahan’s decision in a ruling last October.

“The court found that defendant did not knowingly, voluntarily and intelligently waive her constitutional rights. ... The video recording of defendant’s confession leaves no dispute that the 15-year-old defendant read her constitutional rights out loud and completed a waiver of rights form before any interrogation was conducted about the alleged crimes. However, defendant did not appear to clearly understand her rights from the language on the form,” the court ruled.

The girl’s former attorney said the girl’s family also believes she suffers from post-traumatic stress syndrome and other disorders as a result of being in an abusive home in Poland before she and her younger brother and sister were adopted more than a decade ago by Laurene, a nurse anesthetist and health care manager, and Jeffrey Sikorski, an engineer.

Laurene Sikorski said Roksana is a “loving” girl who “fell under (Rivera’s) spell” after meeting him on Facebook around March 2014.
