This marks one of the first instances of a person’s Facebook activity being used to incriminate her in a state where abortion access is restricted — a scenario that has remained largely hypothetical in the weeks following the US Supreme Court’s decision to overturn Roe v. Wade. Nebraska currently outlaws abortions beyond 20 weeks. On Monday, Republican lawmakers in the state failed to secure enough votes to decrease that window to 12 weeks.

Celeste and her mother were charged in July with allegedly removing, concealing or abandoning a dead human body and concealing the death of another person after the Norfolk Police Department received a tip claiming Celeste had miscarried in April at 23 weeks of pregnancy and secretly buried the fetus with her mother’s help. The case was first reported by the Lincoln Journal Star.

While Celeste told police that she had suffered a miscarriage, they continued to investigate, serving Facebook with a search warrant to access Celeste and Jessica’s Facebook accounts. They subsequently found messages between the mother and daughter allegedly detailing how Celeste had undergone a self-managed abortion with Jessica’s help. There are four states that ban abortion at 24 weeks, and more than a dozen that broadly ban it at the start of fetal viability.
