MADISON, Neb. -- A northeast Nebraska teenager will be sentenced this summer after pleading guilty to a felony related to a high-profile abortion case. 

18-year-old Celeste Burgess pleaded guilty to one count of removing, concealing, or abandoning a dead body as part of a plea agreement in Madison County District Court on Monday. 

The charges were filed after authorities said Burgess, along with her mother Jessica, illegally aborted Celeste's pregnancy and buried the newborn in rural Madison County. 

Prosecutors said in court Monday they estimated the newborn was terminated at 30 weeks into the pregnancy. 

Prosecutors dropped two misdemeanors in return for Burgess' guilty plea. She faces up to two years in prison when she's sentenced on July 20.

As for Jessica Burgess, she's next set to appear in court on July 7 to face multiple felonies, including performing an illegal abortion. 

Prosecutor Joe Smith has said he had never before charged anyone with violating Nebraska’s 20-week abortion limit that was passed in 2010.

According to court documents, Celeste Burgess spoke in online messages that she exchanged with her mom “about how she can’t wait to get the ‘thing’ out of her body.” The messages were obtained in a search warrant.

Last summer, a northeast Nebraska man pleaded guilty to a misdemeanor for helping the women bury the fetus.
