Gabby Petito wrote a letter to her abusive boyfriend, Brian Laundrie, asking him to stop calling her names.
"You know how much I love you. Just please stop crying and stop calling me names because we're a team, and I'm here for you. I'm always going to have your back. ... and I just love you too much, like so much, it hurts," Petito wrote.
"I'm not trying to be negative, but I'm frustrated there's not more I can do," Petito added in the undated letter.
The letter was part of a trove of more than 350 documents released by the FBI about the 2021 murder case that captivated the country.
Petito was reported missing in August 2021 after Laundrie returned to Florida following a cross-country road trip without her. Laundrie then disappeared during the investigation into Petito's whereabouts, resulting in a monthslong manhunt.
Petito's body was eventually found in September 2021 in Bridger-Teton National Forest in Wyoming. Her death was ruled a homicide by strangulation, and Laundrie was identified as the main suspect.
His body was later found in a Florida nature reserve with a self-inflicted gunshot wound. He admitted to murdering Petito in a waterlogged notebook found near his body.
