About the Hosts

Olivia Cornu Profile Photo

Olivia Cornu

Olivia Cornu, star of Married at First Sight: New Orleans and a nurse practitioner in a NeuroICU, had a love of true crime before it was cool. She grew up watching COPS and Unsolved Mysteries, and has always been interested in the psychology behind why people do the heinous things they do. If she wasn’t a nurse, she’d be a forensic investigator. She’ll discuss the science behind it all - what gets a killer caught, and what makes a killer tick.
