Attorney Steven Bertolino tells PEOPLE he has been informed by the FBI they have "everything they need" with respect to their probe into the strangulation death of Petito, the 22-year-old Long Island, N.Y., woman whose August disappearance has made headlines for months. Bertolino first made the revelation in an interview with Fox News, when asked if he expected the FBI would want to meet with Brian's parents, Chris and Roberta Laundrie. Last week, Bertolino told PEOPLE the results of an autopsy on Brian's remains were inconclusive, and that his skeletal remains would be further examined by an anthropologist. Gabby Petito's Friends Say Brian Laundrie's Death Before Truth Is Known Is 'Worst Possible Outcome' They also are not planning a funeral for their son, Bertolino says. The FBI would not confirm or deny Bertolino's assertion. Dental records were used to confirm that human remains found last week in Florida's Myakkahatchee Creek Environmental Park belong to Brian. The body was found next to a notebook and backpack he owned. Brian Laundrie's Parents 'Have No Inkling' What Might Be in Notebook Found Near Remains: Lawyer The 23-year-old fugitive was last seen six days before the body of Petito, his missing fiancée, was found in Wyoming's Grand Teton National Park. According to authorities, Petito died from strangulation while on a two-month-long, cross-country road trip with Brian, who was named a person of interest in Petito's disappearance on Sept. 15 — two weeks after returning home alone. The couple had spent the summer traveling across the country in a white van together, documenting their adventures on YouTube along the way. Petito's family first reported her missing on Sept. 11.

Brian's family refused to meet with the FBI to discuss Petito's missing persons case, referring them instead to Bertolino, a longtime family friend. A week later, the Laundrie family reached out to the FBI to alert investigators that their son was missing. They claimed he was last seen on Sept. 13, after allegedly leaving their home to hike in the nearby Carlton Reserve. Brian Laundrie Was Visibly 'Upset' When He Left Home for Last Time, but Parents 'Couldn't Stop Him': Lawyer The FBI and local Florida authorities quickly launched a search for Brian in the 25,000-acre nature preserve, wading waist-deep through snake- and alligator-infested swamps in some areas. (The Carlton Reserve is connected to the Myakkahatchee Creek Environmental Park, where his remains were eventually found.) Bertolino told PEOPLE that Brian was visibly "upset" the last time that his family saw him. "Yes, Brian was upset when he left and he was not able to be persuaded not to leave the house," Bertolino said. Brian was never charged with Petito's death or disappearance, and a suspect for those crimes has not yet been identified by the FBI.
