Plymouth Township Teen Pleads Guilty in Plot to Kill Family

PLYMOUTH TOWNSHIP, MI – A Plymouth Township teen could spend up to 20 years in prison after pleading guilty Monday for her part in an August 2014 plot with her adult boyfriend to kill her family.

Roksana Sikorski, 16, pleaded guilty to assault with intent to commit murder on the first day of her trial in Wayne County Circuit Court, The Detroit News reports. She will be sentenced on March 28, a week before her 17th birthday. Sentencing guidelines call for a sentence of 10 to 20 years in prison.

Sikorski’s boyfriend, Michael Angelo Rivera, 24, was convicted in August and sentenced to life in prison without parole for his role in the conspiracy.

Sikorski was charged as an adult. In exchange for her plea, the court dismissed charges of conspiracy, assault with a dangerous weapon, felony assault and using a computer to commit a crime.

As Rivera texted her with instructions from outside the upscale Heather Hills subdivision in October 2014, she allegedly stabbed her then-12-year-old brother in the neck while the rest of the family slept. The boy has physically recovered from his injuries.

Earlier in the proceedings, Jeffrey and Laurene Sikorski, Roksana’s parents, argued that she shouldn’t be charged as an adult and that she suffered from post-traumatic stress syndrome after suffering horrific abuse in her former home in Poland.

Laurene Sikorski, a nurse anesthetist and health-care manager, described her daughter as a “loving” girl who “fell under (Rivera’s) spell.”
