Search for Gabby Petito's fiancé Brian Laundrie resumes in Florida's Carlton Reserve

Police say the search for 23-year-old Brian Laundrie is resuming in Florida's Carlton Reserve on Tuesday, a week after his family said they last saw him. Laundrie is a person of interest in the case of his fiancé Gabby Petito, but investigators have not been able to speak with him.

Laundrie and Petito had been on a cross-country trip when Petito disappeared. Laundrie returned to Florida on September 1 without Petito, and 10 days later, Petito was reported missing. 

Police believe they discovered Petito's remains near Grand Teton National Park in Wyoming over the weekend. The Teton County Coroner's Office said it should be done with an autopsy on Tuesday, and the FBI's field office in Denver will release any findings.
