Gabby Petito told ex-boyfriend she wanted to leave Brian Laundrie but was scared to days before he killed her

Days before she was murdered Gabby Petito told her ex-boyfriend she wanted to leave Brian Laundrie – but was fearful of how he might react, a new docuseries revealed.

Petito’s ex-boyfriend, identified only as Jackson, said the two spoke on Aug. 22 after she got into a fight with Laundrie. At the time, he thought the call was a “cry for help,” Jackson told the filmmakers behind Netflix’s docuseries “American Murder: Gabby Petito.”

Jackson recalled Petito telling him, “I have a plan. I think I want to leave him. I’m going to do it. I have to figure out when to do it,” according to USA Today.

“From the sound of her voice and the way she was saying it,” he said. “I think that she wasn’t sure of what he would do or what he could do.”

Petito texted her ex-boyfriend again on Aug. 27 when she and Laundrie were in Jackson, Wyoming, to tell him the town’s name reminded her of him, according to Fox News Digital.

The new docuseries unveiled previously unseen text messages from Petito, as well as interviews with her parents and other loved ones.

Text messages from Aug. 27 shed light on a fight Laundrie was seen having with workers at the Merry Piglets Tex-Mex restaurant in Jackson – which many thought was a catalyst for Laundrie’s rage just hours before Petito’s murder.

Texts show the argument he was seen having with an employee stemmed from Petito claiming the food made her sick.

Witnesses told Fox they believed Laundrie was arguing with the restaurant’s staff about money, and that he left and returned four separate times.

Petito was last seen alive later that afternoon on surveillance footage at a nearby Whole Foods supermarket.

Not long after, police in Moab, Utah, let Petito drive away with Laundrie after intervening in a domestic dispute.

Days later, Laundrie would strangle Petito to death and dump her body in a remote Wyoming campsite, police said.

The young couple had been touring the US in an RV, a journey she documented on social media leading up to her death.

After returning from the trip and hiding out at his parent’s Florida home, Laundrie reported Petito missing, sparking a nationwide search that gripped the country’s attention.

Laundrie later committed suicide in a nearby national park and penned a handwritten note admitting to the murder.

The new docuseries began streaming on Netflix on Monday.
