The disappearance of “van life” blogger Gabby Petito in late August 2021 launched a nationwide effort to locate the 22-year-old who went missing while on a cross-country trip with her former fiancé, Brian Laundrie. That effort ended when Gabby’s body was discovered on September 19 in the Bridger-Teton National Forest in Wyoming. Her death was ruled a homicide.

Now Laundrie, 23, has also become the subject of a large-scale search. The experienced outdoorsman has been named a person of interest in Gabby’s death.

“It’s one rabbit hole after another,” says Gabby’s father, Joe Petito, describing how he constantly imagines his daughter’s last moments alive. “I’ve got a great support system, but it’s hell.”

Joe’s support system includes his wife, Tara, Gabby’s mother, Nichole Schmidt, and her husband, Jim. Watch the video above to hear why the couples say they decided to move their respective families in together temporarily, right after learning about Gabby’s death, and why Nichole says that’s exactly what her daughter would have wanted.
