FBI searches home of Gabby Petito's fiancé Brian Laundrie a day after body found

The FBI on Monday searched the Florida home of Brian Laundrie, weeks after his fiancé Gabby Petito was reported missing. Police believe they discovered Petito's remains in Wyoming over the weekend.

Federal agents searched Laundrie's home Monday for nearly eight hours, questioning his parents and collecting evidence that could tell them what happened to Petito. The manhunt led them to a nearby nature preserve, but investigators found nothing.

Laundrie has been named a person of interest in the Petito case, but investigators have not been able to speak with him. Search warrant documents obtained by CBS News authorized authorities to seize computers, flash drives and other electronics.
