A Florida judge has released a letter written by Brian Laundrie's mother to her son, which was potentially "damning" evidence in the civil trial between the two families next year. The letter was written months before Gabby Petito's death and could provide insight into the events leading up to her death. The judge's decision to release the letter is significant as it could be evidence that the Laundries knew Gabby had been killed and hid that information while helping their son evade authorities.
