Gabby Petito's parents say Christopher and Roberta Laundrie knew their son, Brian, murdered his girlfriend. Petito and Laundrie were on a cross-country road trip last year when Gabby went missing. Her body was later found in Wyoming, and her death is ruled a homicide by strangulation.
Laundrie returned to his parents' Florida home, alone, driving a van owned by Petito. The FBI says Laundrie confessed to killing Petito in a notebook found with his belongings. The Petito family accuses the Laundries of concealing information about their daughter's death and, say the Laundries also tried to hide their son from law enforcement. Brian Laundrie committed suicide in a nature reserve in Florida.
