TAMPA (WFLA) – A public records request from Pinellas County has revealed that Brian Laundrie’s mother Roberta Laundrie checked into a campground at Ft. De Soto Park in early September.

The record of registered campers shows Mrs. Laundrie checked into “Site 001-Waterfront” between Sept. 6 and Sept. 8.

According to the Laundrie’s family attorney Steven Bertolino, the family camped from Sept. 6 til Sept. 7 and “they all left the park.”

Brian, Gabby Petito’s fiancé remains the sole person of interest in the investigation into her disappearance and homicide.

The FBI announced last week that the U.S. District Court of Wyoming issued a federal arrest warrant for Brian Laundrie “pursuant to a federal grand jury indictment” related to his activities following Petito’s death.

The grand jury indictment said Laundrie used a Capitol One Bank debit card and a personal identification number for two Capital One Bank accounts “knowingly and with intent to defraud” between Aug. 30 and Sept. 1 in Wyoming and elsewhere. Using the accounts, he obtained “things of value aggregating to $1,000 or more.”

The Laundrie parents reported their son missing on Friday, Sept. 17. They told North Port police they had last seen their son on Tuesday, Sept. 14. His family told police he went to the Carlton Reserve, a nearly 25,000-acre preserve in Sarasota County. Multiple agencies have spent the past week scouring the area for signs of Laundrie.

North Port police spokesman Josh Taylor said the search for Laundrie will be “scaled back and targeted based on intelligence.”

Pinellas County has directed 8 On Your Side to the FBI Office in Denver for any additional information requests.
