Mary Moriarty Files to Vacate 1998 Murder Conviction After Key Witness Confession

Prosecutors argue the star witness’s late-July change of testimony followed by her admission of guilt undermines the original verdict, prompting calls for a swift hearing.

Overview

  • Hennepin County Attorney Mary Moriarty filed a joint petition with the Great North Innocence Project on August 12 to vacate Brian Hooper Sr.’s 1998 murder conviction.
  • The petition highlights a late-July affidavit in which the prosecution’s key witness recanted her trial testimony and confessed to killing 77-year-old Ann Prazniak.
  • New evidence from the Minneapolis Police Department’s investigation suggests Hooper was not involved in Prazniak’s killing.
  • Other witnesses, including jailhouse informants, have signed affidavits withdrawing their original statements against Hooper.
  • The court has not yet scheduled a hearing and it remains unclear if prosecutors will charge the witness now serving time in Georgia.
