A 14-year-old Allentown, Pennsylvania, girl plead guilty to helping her boyfriend kill her mother.
"I was a monster," Jamie Silvonek told a judge, saying that she deserved the 35 years in prison she got for helping boyfriend Caleb Barnes kill her mother, according to The Morning Call.
"There is no sugarcoating it and there is absolutely no sympathy," she said. "There's no mitigating factors. In my opinion, there's absolutely nothing."
Jamie plead guilty to first-degree murder in the death of 54-year-old Cheryl Silvonek in a hearing that took place a month before the girl's scheduled trial.
Jamie and 21-year-old Barnes had reportedly planned to kill her mother for a week before they actually carried it out on March 15, 2015.
Barnes brutally stabbed the girl's mother in the neck because she allegedly tried several times to break the couple up. She even showed Barnes her daughter's passport in order to convince him that she was too young, reported Lehigh Valley Live.
"She needs to go, Caleb," Jamie reportedly texted Barnes, according to Lehigh Valley Live. "Right now. You don't understand. She threatened to throw me out of the house. I want her gone. I just need to you [sic] be able to come over so we can do whatever necessary, honestly."
Cheryl was reportedly driving the couple to a concert in Scranton when they began plotting to kill her.
"He had proposed that we kill her and we had discussed things such as luring her away, me luring her away," Jamie testified, reported The Morning Call. "And he made a comment such as, 'I already have my knives picked out.' And I was entertaining the conversation."
She was ultimately stabbed while sitting inside of her car while it was parked in her driveway. The couple then buried her body under dirt and snow, and abandoned the car in a nearby pond, according to Lehigh Valley Live.
They were found by police later that night.
At the preliminary hearing for Jamie and Barnes, prosecutors said that her mother begged for her life as Barnes attacked and ultimately killed her.
