Gabby Petito and her fiancÃ© Brian Laundrie's van may have been captured in the background of a couple's anniversary photo, which they took when they visited the Grand Teton National Park, where the 22-year-old woman's remains were found on Sunday.
Brad Arnold, an Alabama-based storm chaser, took to Twitter to share a photo he took of his wife on the last day of his anniversary trip at Grand Teton National Park towards the end of August.
"Maybe it's something or maybe it's not, but it was creepy enough to send chills up and down my spine. This picture of my wife was taken on the last day of our anniversary trip at Grand Teton National Park near the end of August," Arnold captioned the photos.
The picture shows Arnold's wife posing against a scenic backdrop of mountains but close-up shots reveal a white van parked in the background.
