"Burn after reading" letter from Brian Laundrie's mom to Gabby Petito's family revealed in court.

The parents of Gabby Petito have been given a copy of a letter allegedly written by Brian Laundrie's mother, Roberta Laundrie, instructing him to "burn after reading." The letter, which can be included as evidence in the Petitos' civil lawsuit against the Laundries and their lawyer, reportedly contains phrases that suggest Roberta Laundrie was willing to help her son dispose of a body. Gabby Petito died of homicide by manual strangulation during a 2021 cross-country road trip with Laundrie, who returned to Florida alone and later died of a self-inflicted gunshot wound.
