The woman who says she was Gabby Petito’s best friend worried when the 22-year-old was first reported missing because her boyfriend, Brian Laundrie, “knows where I live and he does not like me.”

Rose Davis — who previously said Laundrie didn’t like how close she was with his girlfriend, as CrimeOnline previously reported — told PEOPLE Magazine that she’d become friends with him too.

“You don’t know what it’s like for someone you considered a friend to murder your best friend,” she said. “I’ve stayed at their house. I’ve slept in the same house as him. I ate dinners with him, played board games with him, gone to the beach — even though he didn’t really hang out with us at the beach — but going to the beach with him. That’s scary.”

Officials have not named Laundrie a suspect in Petito’s murder, although he has been named a person of interest. Additionally, a federal grand jury has indicted him on bank fraud charges for allegedly using Petito’s debit card to take money out of her accounts, prompting a warrant for his arrest.

Davis, 21, earlier said that Laundrie had gone on long-term camping trips in the past — specifically mentioning the Appalachians, although she didn’t specify if he had been hiking the Appalachian Trail, a frequent spot for long term hikers and campers. It was likely Petito’s and Laundrie’s mutual love of the outdoors that sparked the cross-country van trip that began on July 2 and ended with Petito dead in a remote Wyoming camping area and an FBI manhunt for her boyfriend.

Davis also said that Laundrie appeared to have few, if any friends.

“He does not have friends,” she told PEOPLE. “He reads books.”

“This is a very heartbreaking tragedy,” Davis said. “It is so surreal. It is so just horrific. There’s almost a loss of words for it because no one deserves to go out this way, especially not her.”
