Chilling letter Brian Laundrie's mom wrote to him after he killed girlfriend Gabby Petito revealed

The mother of Gabby Petito's killer Brian Laundrie wrote him a chilling 'burn after reading' letter in which she said she would help him bury a body because she loved him so much. Petito was killed by her fiancé Laundrie in Wyoming while they were on a road trip in the summer of 2021. Investigators determined she died by manual strangulation and had been dead for three to four weeks, and her death was ruled a homicide.

Laundrie later died by suicide from a gunshot wound to the head in October 2021. His remains were found in Florida's Carlton Reserve. Before Petito's remains were discovered - and when Laundrie went on the run - FBI agents searched his home and found that his mother, Roberta Laundrie, had penned a shocking personal note. The note, which she maintains was written before he killed her during their road trip across the country, is laid bare in Netflix's new documentary series American Murder: Gabby Petito, which premiered on the platform on February 17.

Speaking in the documentary, FBI special agent Loretta Bush, said: 'We searched Brian's house and collected potential evidence. 'Among his belongings there was a note that Brian's mother had written to Brian, and it was titled "burn after reading.". Roberta Laundrie wrote her son, killer Brian Laundrie, a chilling 'burn after reading' letter which was found by FBI agents. Petito was killed by her fiancé Laundrie in Wyoming while they were on a road trip in the summer of 2021.

'It said: "You are my boy. Nothing can make me stop loving you. Nothing will or could ever divide us, no matter what we do. '"If you're in jail, I'll bake a cake with a file in it. If you need to dispose of a body, I will show up with a shovel and garbage bags."'. Responding to the letter, Gabby's stepmother, Tara Petito, said: 'The first time we saw that letter we were just so in shock and angry, how could she write this letter? It's just disgusting.'.

Petito's mom Nichole Schmidt admitted the letter made her 'sick to my stomach.'. 'It's just disgusting,' she added. Petito's friend, Rose David, remarked: 'I think the burn after reading letter from Roberta is disgusting. 'I personally love my mother, but I'd be very concerned if she sent me a letter like that.'. Roberta previously claimed that she wrote the letter before his fateful road trip with Petito which began on June 2021.

The letter (pictured) was undated, with Roberta claiming she had written in before the young couple embarked on a cross-country van trip. In the note, Roberta said she would 'dispose of a body' if needed because she loved him so much. The note was made public following a hearing in the civil suit brought by the Petitos against the Laundries. Roberta's attorney released a statement to say it was 'in no way related to Gabby.'.

'The letter to Brian was written prior to Gabby and Brian leaving my home for their trip,' the statement read. 'Previously, I submitted an affidavit to the court for very limited purposes but that is not the whole story,' she said. 'Now that the letter has been shared, I ask that you read it in its entirety and understand that the letter contains other phrases besides those highlighted by Pat Reilly (the Petitos' attorney) for sensationalism and to bolster his case.'.

Petito vanished while on a cross-country trip in a converted camper van with her boyfriend. Laundrie took responsible for Petito's death in a suicide note which was found near his body. In her statement to the court, Roberta admitted her letter did contain references that some would think were about her son and Petito, but she maintained there is 'no connection' between her letter and the deaths. 'While I used words that seem to have a connection with Brian's actions and his taking of Gabby's life, I never would have fathomed the events that unfolded months later between Brian and Gabby would reflect the words in my letter.
