A coroner has determined Gabby Petito was strangled to death. The 22-year-old's body was found in Wyoming last month. She had been on a cross-country trip with her fiancé, Brian Laundrie, who remains the only person of interest in her murder. Forensic pathologist Dr. Priya Banerjee joined CBSN's Elaine Quijano to discuss.
