The boyfriend of Gabby Petito, whose body was found at a national park in Wyoming after a cross-country trip with him, was charged with unauthorized use of a debit card as searchers continued looking for him in Florida swampland.

A federal grand jury indictment filed in U.S. District Court in Wyoming alleges Brian Laundrie used a Capital One Bank card and someone’s personal identification number to make unauthorized withdrawals or charges worth more than $1,000 during the period in which Petito went missing. It does not say who the card belonged to.
