Sept. 18 (UPI) -- The family of Brian Laundrie has reported him missing amid an investigation into the disappearance of his fiancée, Gabby Petito, police in Florida said.
The North Port Police Department issued a plea to the public Friday for information on Laundrie's whereabouts.
"The attorney for the Laundrie family called FBI investigators Friday night indicating the family would like to talk about the disappearance of their son," a statement from the department said. "The family now claims that they have not seen Brian since Tuesday of this week."
The North Port police have sought to interview Laundrie, 23, in connection with the disappearance of Petito, 22. Her family reported her missing Sept. 11, saying they last spoke with her Aug. 25 when she was believed to be in Grand Teton National Park in Wyoming.
Petito and Laundrie were on a cross-country road trip, which was being documented by the engaged couple on social media. The couple left for the trip in July and Laundrie returned to the Florida home they shared with his parents on Sept. 1, allegedly without Petito.
Police said Laundrie and his family has been uncooperative since Petito was reported missing.
Police in Moab, Utah, on Thursday released body-worn camera footage from an encounter they had Aug. 12 with the couple. They conducted a traffic stop on the van in which they were traveling.
In the footage, Petito can be seen crying, saying she and Laundrie had been having an argument because of "personal issues" and that she had slapped him. Police separated the two for the night, sending Laundrie to a hotel room and Petito staying with the van.
