Gabby Petito's heartbreaking love letter to killer boyfriend Brian Laundrie revealed

Gabby Petito had pleaded with boyfriend Brian Laundrie to stop calling her names as she professed her love for him in a heartbreaking love letter sent before their ill-fated trip in 2021.

'Brian, you know how much I love you, so (and I'm writing this with love), just please stop crying and stop calling me names because we are a team and I'm here with you,' Petito wrote in the undated letter included in a trove of documents released by the FBI on Monday.

The 22-year-old travel blogger went on to apologize for getting 'upset over a dumb piece of paper,' though it is unclear what the argument was about.

'Yes, I can be a child sometimes, I know, but it's cause you give me this energy and I just love you too much, like so much it hurts,' Petito wrote.

'So you in pain is killing me,' she said. 'I'm not trying to be negative, but I'm frustrated there's not more I can do.' 

Gabby Petito, 22, wrote a heartbreaking letter to her then-boyfriend Brian Laundrie professing her love and pleading with him to stop calling her names

The two took a cross-country van trip in 2021, when Laundrie killed Petito 

Petito then promised that when she returned from New York she would work with him on the van they would take to cross the country.

'We can work on the van together and they are OUR dreams now,' she noted.

'So I hope you understand when I'm upset it's cause I love you too much,' Petito concluded.

'Now stop crying!!! And come home and say you love me with a big hug.' 

Laundrie would go onto murder Petito as they traveled across the country, leaving her body in Wyoming's Grand Teton National Park, while he returned to Sarasota, Florida alone. 

He would later go missing himself, and was found dead of a self-inflicted gunshot wound to the head.

As a frantic search for the 22-year-old blogger continued, agents raided Laundrie's parent's house in south Florida - the contents of which they have recently released in a nearly 400-page document on Monday.

Along with the heartbreaking love letter, the newly-released evidence included drawings from Laundrie's notebook.

One appeared to show a skull surrounded by the words 'kill' and in another he repeatedly wrote the words 'trust nobody.'

Laundrie also wrote about his mental health struggles, noting at one point that he was contemplating suicide and kept a revolver under his mattress.

In one journal entry, Laundrie repeatedly wrote 'trust no one'

'About a year ago I went in to a type of mania where I was smashing holes in the wall with my head, kicking throug (sic) paintings, tearing whatever I was working on, pouring gasoline on myself to burn alive but getting the lighter wet, parking out in murderland listening to Mac [unclear, but may be 'DeMarco'] with a gun to my head, wrestling alligators,' Laundrie wrote in his diary on October 26, 2018.

'I wanted to die and the weird thing is nothing's changed, but the [timer's] running down.

'Under the mattress I'm on is a loaded 357 magnum revolver. A pull of the trigger and all my problems will be over,' he wrote.

In another undated diary entry Laundrie described a nightmare he had which appeared to be about Petito leaving him.

'The ocean pours out of her blue eyes and the fire is out. With one word the pain is gone. "Brian?,"' Laundrie wrote.

'Oh how sweet she is to say we should get together, but you know when you walk out that door she’ll be gone forever again. Your (sic) back in the car, haunted by the eyes you’ll never look into again.'

'The pain burns fresh because you know it’s just tonight. You wake up and your (sic) both free,' Laundrie wrote.

Laundrie left Petito's body in Wyoming 's Grand Teton National Park, while he returned to Sarasota, Florida alone, where he would later die of a self-inflicted gunshot wound 

Other items the FBI collected include hundreds of bullets, several magazines, and a bill of sale and handbooks for Ruger .380 and Glock 49 mm pistols and a compound bow fitted with a rifle scope.

Reading material found included copies of 'The Watchtower,' an illustrated religious magazine published by New-York based Jehovah’s Witnesses, and Chuck Palahniuk’s novel, 'Choke,' about a scam artist who pretends to choke on food to earn sympathy checks from others. 

Near Petito's body, agents also noted in an affidavit supporting a search warrant application for Laundrie's home they found two arrows and a 'revolver speed loader containing ammunition.'

The FBI was subsequently able to find that Laundrie had written in a notebook that he was responsible for the death of Petito. 

An attorney representing the Petito family told the New York Post the documents prove Laundrie 'was clearly a narcissist and manipulator capable of violence.'
