A Nebraska teen has been sentenced to 90 days in jail after being accused of getting an illegal abortion — and prosecutors used Facebook messages between her and her mother to charge them.

On Thursday, the 19-year-old was sentenced for disposing of the fetus after an abortion. The teen had pleaded guilty in May to one count of removing, concealing, or abandoning a dead body, according to News Channel Nebraska Central.

The plea was part of a deal with Madison County prosecutors, who dropped two misdemeanors in return.

The teen's mother was also charged with assisting her daughter with the abortion, and she pleaded guilty earlier this month, according to NBC News.

Police originally arrested the mother and daughter after gathering evidence from Facebook messages between the two discussing how to get and use abortion pills, according to court records.

Prosecutors allege the 41-year-old mother acquired and gave the pills to her daughter, who was 17 at the time.

They then buried and reburied the fetus.

In the Facebook messages turned over by the social media giant, the teen told her mother that she "can't wait to get the 'thing' out of her body," detectives wrote in court documents.

Nebraska has extremely strict abortion laws, including a restriction passed in 2010 that prohibits the procedure after 20 weeks.

The state legislature has since passed a 12-week abortion ban.
