What happened

The three-part series, which chronicles the 2021 murder of 22-year-old Gabby Petito by her fiancé Brian Laundrie, employed voice recreation technology to narrate Petito's personal writings. 

While the filmmakers obtained permission from Petito's family, the decision sparked ethical debates and left some viewers feeling uncomfortable. 

The AI-generated voice, described as "a little off" by Petito's mother, was criticised as potentially disrespectful to the victim's memory and raised questions about the appropriate use of AI in portraying real-life tragedies.

Why it happened

The filmmakers justified their decision by stating they wanted to tell Petito's story through her own words, believing it would bring her writings to life and enhance the emotional impact of the documentary. 

They worked with extensive material provided by Petito's family, including journals and documented trips from her youth.
