Gabby Petito case: Timeline of travel blogger's disappearance

Petito had been traveling with her boyfriend, Brian Laundrie, in a white van.

Eleven days into the search for missing travel blogger Gabrielle "Gabby" Petito, authorities reported Tuesday that human remains recovered two days prior at a national park in Wyoming had been positively identified as Petito and that she had died as a result of homicide.

Petito had been traveling with her boyfriend, Brian Laundrie, in a white van, and the two were documenting their cross-country road trip on a YouTube channel and on Instagram.

"There is nothing else that matters to me," said Petito's father, Joe Petito, during a press conference on Thursday. "This girl is what matters, anything else comes to second to this."

Police named Laundrie a person of interest last week, though federal and state authorities continue to work to piece together evidence from the last three months.
