Gabby Petito’s family calls for Brian Laundrie to 'turn yourself in'

NORTH PORT, Fla. - Gabby Petito’s family gathered Tuesday to thank law enforcement for their efforts to find their missing loved one and showed off matching tattoos in her memory. But with the hunt for her fiancé still underway, they had one message for Brian Laundrie: "Turn yourself in."

Laundrie, 23, has not been seen in at least two weeks. His parents – Chris and Roberta Laundrie – told North Port police he went to the Carlton Reserve in Sarasota County with only a backpack and disappeared. The search continued even as the Petito family gathered 1,200 miles away in New York to discuss their next steps.

"The Laundries did not help us find Gabby. They sure aren’t going to help us find Brian," attorney Richard Stafford said. "For Brian, we are asking you to turn yourself in."

Gabby's family announced plans to create the Gabby Petito Foundation as a way to take something positive from her case.

"We can’t let her name be taken in vain," said Gabby's father, Joseph. "We need positive stuff. Anything we can do to bring that up and help people."

Stafford said the family was "100%" satisfied with the FBI investigation, while Joseph said social media has also been "very influential" in the investigation. 

"To be honest, it should continue for other people too," he offered. "This same type of heightened awareness should be continued for everyone." 

Jim Schmidt, Gabby's stepfather, said the family has not yet received Gabby’s remains from the coroner’s office in Wyoming. Schmidt also said he has not yet received any of her possessions from Florida.

"When they are ready to release her, we will be bringing her home," he added.  

The family members all showed matching tattoos they had gotten in honor of Gabby. "Let it be" was written on their arms – each a copy of a tattoo Gabby had.

Yesterday, the Laundrie family released a statement of their own. In response to the criticism they’ve faced over their refusal to help law enforcement while Gabby was still missing and the accusation that they’ve helped their son escape, their attorney said Brian’s parents do not know where he is, and that speculation they assisted him in leaving the family home or in avoiding arrest is just wrong.

"Chris and Roberta Laundrie do not know where Brian is. They are concerned about Brian and hope the FBI can locate him. The speculation by the public and some in the press that the parents assisted Brian in leaving the family home or in avoiding arrest on a warrant that was issued after Brian had already been missing for several days is just wrong," attorney Steven Bertolino said in the statement.

Brian Laundrie search

After days of intensive searching, authorities scaled things back in the Carlton Reserve, now relying primarily on aerial surveillance. 

FOX News spoke with a local cattle rancher who’s been part of those search efforts. He’s spent 30 years riding the swampy terrain, saying he doubts anyone could survive more than a few days there.

"There’s no surviving out here, I don’t know how to say it," said Alan McEwen. "I’ve been in the woods in and out all my life … I have learned a lot in my life, and one thing I know is no one is gonna survive out there for two weeks on foot."

The FBI has taken over all aspects of the Laundrie case. They’ve gathered DNA from his home to use in order to match to any remains or items they may find  

Brian and Gabby went on a cross-country trip in her Ford Transit van back in late June. In mid-August, the two had a run-in with police officers in Moab, Utah, after the couple got into a physical altercation outside of the Moonflower Market.

Gabby's mother says the last time she's sure she spoke to her daughter was August 25, when Gabby told her mother she and Brian were headed to Grand Teton National Park.

"I don't know if she left Grand Teton or not," Nicole Schmidt later told FOX News. 

However, on Aug. 27, Schmidt said she got a text message from Gabby's phone, but she is not convinced the message was from her daughter.

On September 1, Brian arrived back at his parents' house in North Port, Florida, driving Gabby's van. Gabby was also living there, but she was nowhere to be found. She was reported missing by her parents Saturday, Sept. 11. Her remains were later discovered in Grand Teton National Park.

Brian's car was brought back to the Laundrie's home from the reserve that Thursday, His parents reported him missing Friday, Sept. 17.

Immediately after Brian was reported missing, a search of the 25,000-acre reserve began, involving agencies from the North Port Police Department to the FBI. 

Meanwhile, investigators continued to try to develop leads in the case and Brian's whereabouts.

On Sept. 20, FBI agents hauled carloads of evidence from the Laundrie home as the search at Carlton Reserve expanded to include dogs, airboats, ATVs, and aircraft from multiple agencies. 

During the search's fifth day, the FBI issued an arrest warrant for Laundrie for charges "related to Mr. Laundrie’s activities following the death of Gabrielle Petito," specifically his "unauthorized" use of a debit card in the wake of Petito’s death. A North Port law firm also announced a $20,000 reward for information leading to Laundrie's location.

Gabby Petito death

Gabby was not reported missing until 10 days after Brian's return to North Port. Her mother filed a police report in Suffolk County, N.Y. Police seized the van from the Laundries' home on Sept. 11. 

The remains were discovered Sept. 19 in the Bridger-Teton National Forest after a national search for the 22-year-old. Video captured by a vacationing Tampa family accidentally caught what appeared to be the couple's van parked at the Spread Creek Dispersed Camping Area in the forest; Gabby's body was later found nearby.

A coroner confirmed that a body found Sunday in Wyoming was indeed Gabby. They said the manner of death was homicide. The exact cause is still being determined.

One week after Gabby's remains were discovered in Grand Teton National Park, a funeral service and memorial was held in Long Island. 

Brian was later named a person of interest in her disappearance.
