A rainbow appeared in the area where authorities discovered the body of Gabby Petito in Grand Teton National Park.
The cause of death has not yet been determined, said FBI Supervisory Special Agent Charles Jones. No details on where and how the body was found were disclosed.
The FBI are now looking for 23-year-old fiancé Brian Laundrie, who has also been reported missing in Florida. The FBI said, "he is a person of interest."
