Overview

  • Margaret Brown’s four-part docuseries premiered on HBO and HBO Max on August 3 and revisits the unsolved killings of four teenage girls in 1991.
  • The series weaves in archival interrogation footage from Claire Huie’s unfinished 2009 documentary as well as fresh interviews with victims’ families, retired investigators, and “48 Hours” correspondent Erin Moriarty.
  • It highlights investigative failures by former APD detective Hector Polanco, whose alleged coercion of confessions prompted his removal and tarnished early leads.
  • A 2009 DNA analysis excluded former suspects Robert Springsteen and Michael Scott and pointed to unknown perpetrators whose profiles are now central to ongoing forensics.
  • Jackson says he is confident that evolving forensic technology can solve the cold case and urges tipsters to share any information they may hold.
