Post Mortem | Joe Hunter’s Mission

48 Hours correspondents Anne-Marie Green and Natalie Morales discuss “Survivor” contestant Joe Hunter’s mission to raise awareness about his sister, Joanna, who was found dead in her California home in 2011. Joe and his family believe that Joanna’s husband, Mark Lewis, killed her and staged it to look like a suicide. But the Solano County Sheriff’s office says Joanna was not murdered. Mark Lewis has never been charged with any crime relating to her death.
