(NEW YORK) — A massive search is continuing in Florida for Brian Laundrie, the boyfriend of Gabby Petito, the 22-year-old woman who went missing on a cross-country trip and who authorities confirmed as the body discovered strangled to death in Wyoming last month.

The search for the 23-year-old Laundrie is centered around North Port, Florida, where investigators said Laundrie returned to his home on Sept. 1 without Petito but driving her 2012 Ford Transit.

Laundrie has been named by police as a “person of interest” in Petito’s disappearance. Laundrie has refused to speak to the police and has not been seen since Sept. 14, according to law enforcement officials.

The search for Laundrie is the latest twist in the case that has grabbed national attention as he and Petito had been traveling across the country since June, documenting the trip on social media. Petito’s parents reported her missing on Sept. 11 after not hearing from her for two weeks.

Laundrie family attorney reacts to discovery of apparent human remains

Steven Bertolino, the family attorney for the Laundrie family, spoke with New York ABC station WABC Wednesday evening after law enforcement found human remains and items belonging to the fugitive at a Florida park.

The attorney said the area where investigators found Brian’s belongings was shown to police two weeks ago when Laundrie’s father, Chris, aided in the search.

“I can’t say for certain that Chris showed this particular area to police at that point in time, but I can say that this is an area that we initially notified the FBI that Brian liked hiking,” Bertolino said.

The attorney said the family is waiting for a proper identification before making any comments.

“As you can imagine, the parents are very distraught. … At this moment in time they’re grieving,” he said.
