A 14-year-old Pennsylvania girl accused of plotting with her soldier boyfriend to kill her mother has pleaded guilty in a deal with prosecutors.

The Lehigh County district attorney's office says Jamie Silvonek entered the plea Thursday and will be sentenced to 35 years to life in prison.

Senior Deputy District Attorney Jeffrey Dimmig says as part of the deal, Silvonek will be eligible for parole after serving 35 years.

She was accused of conspiring with 21-year-old Army Spc. Caleb Barnes via text to kill her mother in the driveway of her home near Allentown in March.

Fifty-four-year-old Cheryl Silvonek was beaten, choked and stabbed in her SUV.

Prosecutors say she'd told her eighth-grade daughter to end the relationship because Barnes was too old.

Barnes' trial is set for April 11.
