NORTH PORT, Fla. – Brian Laundrie’s mom Roberta did check in to a Florida park about 75 miles north of the family’s home earlier this month, records obtained by Fox News show.

Laundrie, 23, vanished on Sept. 14 – although his parents didn’t say anything until three days later. His 22-year-old fiancée Gabby Petito was found dead in Wyoming on Sept. 19 – weeks after the couple was seen camping near the site of her remains. The coroner later ruled her death a homicide.

Duane "Dog" Chapman, also known as Dog the Bounty Hunter, announced Saturday he was entering the search for Laundrie, and tips quickly poured in. He told Fox News he received a heads-up on Monday that Laundrie’s parents spent the night in Fort De Soto Park with their son twice in early September from Sept. 1 to 3 and Sept. 6 to 8.
