Rebecca Lynn O’Donnell, 48, of Pocahontas, also faces charges of tampering with physical evidence and abuse of a corpse. She appeared Monday morning in Randolph County Circuit Court.
No bond was set, the Jonesboro TV station reported. Further details on the case were not released at the hearing.
Collins was found dead at her home in Pocahontas on June 4. Ken Yang, her former press secretary, said she'd been shot.
O'Donnell was arrested Friday in the case. Photos posted online and court records show that O'Donnell and Collins knew each other. O'Donnell appeared as a corroborating witness in Collins' divorce case with ex-husband and former circuit judge Phil Smith, according to court records.
Collins was a Republican state representative from 2011-2013. She served in the state senate from 2015-2019.
