(NORTH PORT, Fla.) -- 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 in the Bridger-Teton National Forest in Wyoming.
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 Tuesday, 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, who live in Long Island, New York, reported her missing on Sept. 11 after not hearing from her for two weeks.

Brian Laundrie's father joins police in search for son: Attorney
The father of wanted fugitive Brian Laundrie joined law enforcement officers in the search for his son on Thursday, the family's attorney told ABC News.
Chris Laundrie began assisting police Thursday morning in the ongoing search of the 25,000-acre Carlton Reserve, near his home in North Port, said attorney Steven Bertolino.
He said the father has been asked to point out any favorite trails or spots in the nature preserve that his son favored. Chris Laundrie and his wife, Roberta, verbally told investigators roughly three weeks ago where their son may have gone in the preserve, but now searchers believe the father's on-site assistance may be more beneficial, Bertolino said.
The preserve has been closed to the public and the Laundries as well. The parents, according to Bertolino, have been cooperating since the search began.

Laundrie family attorney Steven Bertolino confirmed to ABC News Tuesday night that the family now believes Brian Laundrie left to hike the Carlton Reserve on Monday, Sept. 13. Previously, they had told investigators he left on Tuesday, Sept. 14.

Upon further communication with the FBI and confirmation of the Mustang being at the Laundrie residence on Wednesday September 15, we now believe the day Brian left to hike in the preserve was Monday September 13,” Bertolino said.

Brian Laundrie flew home to Florida in early August: Family attorney
An attorney for the family of Brian Laundrie confirmed to ABC News on Tuesday that the wanted fugitive flew home to Florida from Salt Lake City on Aug. 17 and flew back to Utah six days later to rejoin his girlfriend, Gabby Petito, on their cross-country road trip.
Steven Bertolino said Laundrie flew home to "obtain some items and empty and close the (couple's) storage unit to save money as they contemplated extending the road trip." Bertolino said the couple paid for the flights together as they were sharing expenses.
Laundrie's trip back to the Tampa area came five days after he and Petito were stopped by police in Moab, Utah, when witnesses reported the couple was engaged in a domestic violence incident in Moab.
