Natalie Morales, with over 25 years in journalism, considers the case of Survivor alum Joe Hunter and his sister, Joanna, among the most significant true crime stories she has covered.
The episode titled “Joe Hunter’s Mission” on 48 Hours, where Morales, 53, serves as the lead correspondent, explores their story.
“It’s incredibly emotional,” Morales shared with Us Weekly. “Possibly one of the most pivotal true crime stories I’ve tackled.”
Joanna, aged 36, was found dead in her California residence in 2011, with police ruling it a suicide. Her husband, Mark Lewis, reported discovering her body, claiming no evidence of struggle, suggesting suicide.
Despite the ruling, Joe and his family doubted this conclusion. Lewis had a history of domestic violence, and inconsistencies soon raised questions about the investigation. Although the case has been revisited, Joanna’s cause of death remains unchanged, and Lewis, who denies any wrongdoing, has not been charged.
“Joe felt he failed his sister and wanted to be her voice while on Survivor,” Morales said. “He aimed to honor her memory and bring attention to domestic violence survivors.”
The Hunter family has actively worked to raise awareness, which fueled Morales’ passion for the story. Joe and his mother, Patricia, were instrumental in passing Joanna’s Law in California, signed by Governor Gavin Newsom in 2024.
This law mandates that law enforcement examines ten factors in suspicious deaths with a history of domestic violence before closing the case. These factors include one partner wanting to end the relationship and the deceased being found by their partner.
Joanna’s death met all ten criteria, yet it was never investigated as a homicide.
“The officer took photos, collected the alleged suicide note, but didn’t swab for DNA or document the scene,” Morales explained.
This oversight meant crucial evidence, including a rope believed by a doctor to be the murder weapon, is now missing.
“I learned about hidden homicides through this case,” Morales said. “It made me reconsider past stories and question if investigations were thorough.”
“Joe Hunter’s Mission” not only explores the case but also delves into Joanna’s troubled relationship with Lewis, who had a history of abuse. Despite attempts to leave, Joanna repeatedly returned.
Lewis has not commented on Joanna’s allegations and declined to participate in 48 Hours.
“Many suffer silently in domestic violence situations,” Morales said. “Fear often prevents them from speaking out or leaving.”
The episode “Joe Hunter’s Mission” will air on CBS on Saturday, December 13 at 10 p.m. ET and will be available on Paramount+.
