Davis continued: “He did have jealousy issues and that was apparent. I mean that you could see right through it when after you hang out with them just a few times.”
Her death has been deemeda homicide.
Petito was last seen in late August, while on a cross-country road trip with Laundrie, 23.
Davis tells PEOPLE she remembers expressing concern to her mother after first meeting Laundrie, telling her at the time, “He’s a little weird.”
“I said, ‘Something’s a little off about him. I don’t know what.’ It was the first thing I said. My mom said that to me when she went missing. She was like, ‘Didn’t you say he was weird?'”

Davis says that in her opinion Laundrie is “a sociopath” who was adept at lying. Petito would often talk to her about the blowout arguments and tense fights she’d had with Laundrie.
Davis tells PEOPLE that over the course of their two-year friendship, Petito often came to her home after arguments with Laundrie.

“He could keep an eye on her at Publix,” Davis says. “He didn’t want her to work, and she did. And he was mad about it. And he always tried to get what he wanted and he did, because he wanted the van life and he rushed to that so that she wasn’t going to be able to work anymore.”
According to Davis, Laundrie wasn’t supportive of Petito’s social media aspirations to chronicle their travels and offer road trip hacks. This, she believes, is “a sign of domestic abuse.”

Davis says she recognized the distressed version of Petito she saw in body camera footage of the couple’s interactions with police in Moab, Utah, last month.

“I have seen her like that, and it’s always the same situation,” she says. “And she always defends him. But she was getting so much more comfortable with me, and I swear this is why he rushed the van life trip — because he knew that I gave her a safe place. She would come to my house when I wasn’t even here, and stay here for hours.”
