Mother of Gabby Petito's killer offers to help dispose of body in letter.

The mother of Brian Laundrie, who killed Gabby Petito, wrote a letter to her son saying she would "dispose of a body" if needed because she loved him so much, according to copies of the note shared publicly for the first time this week by attorneys for Petito's parents. The handwritten note by Roberta Laundrie was released after a Florida judge ruled on Wednesday that the letter could be used as evidence in a lawsuit. The Petitos sued Brian Laundrie's parents, accusing them of knowing that their son had murdered Gabby Petito and helping him with the coverup for nearly a month before her body was found in western Wyoming in September 2021.
