PIKETON, Ohio (AP) — A woman facing charges in connection to an Ohio family massacre is to go before a judge and ask that her charges be dismissed.

Prosecutors are opposing the request and also want a gag order to stop Fredericka Wagner from speaking about the case. A hearing is set for Thursday.

Wagner’s son, daughter-in-law and two grandsons are accused of killing eight members of the Rhoden family in Pike County in 2016. All four have pleaded not guilty.

Prosecutors say Wagner lied to investigators after they found two bulletproof vests at her home. Wagner says she bought them after the killings to protect her family.

The 76-year-old has pleaded not guilty to obstruction and perjury charges and is under house arrest.

She says her family had no role in the killings.
