Gabby Petito’s mother has alleged that Brian Laundrie’s parents know “a lot more information than they are putting out there”.

Speaking on Good Morning America, Nichole Schmidt told the host Phil McGraw that “somebody needs to start talking” when she was asked whether she believed the Laundries knew about their son’s whereabouts.

Steven Bertolino, the attorney representing Mr Laundrie’s parents, has said that “Chris and Roberta Laundrie do not know where Brian is. They are concerned about Brian and hope the FBI can locate him.”

Gabby Petito and her boyfriend Brian Laundrie got matching tattoos to “represent them and their love” before going on their road trip in July this year, it was reported.

A tattoo artist, Danny Nostrom, told the Daily Mail that they were “super excited” when they walked into his parlour in Venice, Florida in October last year to get the tattoos.

Mr Nostrom said: “They had texted for an appointment and were referred by a friend. They knew exactly what they wanted.”

He added: “They said they wanted a couple of vines around each one of their fingers to represent them and their love and the fact they were planning this big trip together.”

Duane Chapman’s daughter has claimed that their team is receiving a “ton of information” about Brian Laundrie and his whereabouts and added that “we are sorting” through it all.

Lyssa Chapman tweeted that they had to “let things cool down” due to all the media coverage and claimed that tips are once again “becoming more streamlined and verifiable.”

Meanwhile, Gabby Petito’s family has urged Mr Laundrie to turn himself in.

Richard Stafford, the attorney representing the Petito family also alleged that Mr Laundrie stole Gabby Petito’s credit card after her death and used it to get home to Florida.

The FBI launched a massive manhunt for the missing boyfriend almost two weeks ago and Duane Chapman, aka Dog the Bounty Hunter launched a parallel search for Mr Laundrie too.

A renowned forensic pathologist has called the FBI’s decision to withhold Gabby Petito’s remains from her family “unusual.”

Dr Michael Baden also said that it was “very unusual” that the agency has not released the 22-year-old YouTuber’s cause of death even now.

He told Fox News: “I think the FBI would be very cautious about things because they don’t want to make a mistake. Whatever reasons they’re withholding, it is very unusual.”

Dr Baden added: “I think that the only reason would be, you’re concerned that you’re missing something, but that should not be a concern, because whatever is needed to investigate the death from the point of view of the medical examiner will be seen, documented and could be retained.”

Brian Laundrie’s sister, Cassie Laundrie, has said that her brother returned home on 17 August, after Utah police pulled the couple over during a fight.

Ms Laundrie and her husband James Luycx took questions from a group of protesters outside her home, sharing the little they know on the case of the 22-year-old travel blogger Gabby Petito, who was found dead in Bridger–Teton National Forest in Wyoming.

On Monday, Ms Laundrie confirmed that her brother flew home to Florida on or before 17 August, and rejoined Ms Petito before returning home alone with her van on 1 September. She says she saw him on 1 September, reported NewsNation Now.

She claimed she learned of Petito’s disappearance when questioned by police on 11 September. Asked if she knew if her brother had killed Petito or if he was dead she said “I don’t know”.

Jade Bremner reports.

“I’m on the highway right now but I ran into Brian Lower [sic] just a little while ago,” the caller said, mispronouncing Laundrie’s surname.

“He’s waving his arm out of, out of his truck like for me to slow down, and I pull up next to him… he was talking wild, he said that his girlfriend loved him and he had to go out to California to see her, and he was asking me how to get to California.”

“I’m 99.99 per cent sure that was him,” he added.

Brian Laundrie allegedly stole Gabby Petito’s credit card after her death and used it to get home to Florida, the Petito family lawyer has revealed.

The FBI charged Mr Laundrie with illegally used a debit card and PIN number for charges totaling more than $1,000 after he went missing, but did not name who the card belonged to.

In an interview with Ms Petito’s parents and their attorney Richard Stafford on Dr Phil on Tuesday, the family revealed the card at the centre of the fraudulent transactions had belonged to Ms Petito.

Discussing Mr Laundrie’s actions since Ms Petito’s disappearance, Mr Stafford said: “I’m sure the FBI has a lot more evidence than we have. You could look at his state of mind by his actions.

“He ran. He stole her credit card. He used her credit card to get home and then ran from the police. That’s going to show what he was thinking.”

Bevan Hurley reports.

The sister of Brian Laundrie went on a Labor Day camping trip with her family , despite claiming she hadn’t seen the missing man since he returned to Florida alone.

In comments to ABC News two weeks ago, Cassie Laundrie said she hadn’t seen Mr Laundrie since he returned to his parent’s home in North Port, Florida, on 1 September without Gabby Petito.

But in a text message to Newsnation reporter Brian Entin, Laundrie family attorney Steve Bertolino said Ms Laundrie had joined the family on a camping trip to Fort De Soto Park on 6 September.

Bevan Hurley covered the previous timeline change from the Laundrie family.

The Guinness World Record holder for most identifications by a forensic artist told News Nation Now that Brian Laundrie would likely have shaved his beard, may have died his hair bleached blond, and would be wearing a hat and/or sunglasses.

Lois Gibson created six forensic sketches showing potential new looks for the missing boyfriend of Gabby Petito.

“He (Laundrie) has like super distinctive facial hair,” Gibson said. “It’s incredibly distinctive. So if I were him, I would shave.”

“I believe he will always wear a ballcap,” she added.

The lawyer for Brian Laundrie said the boyfriend of Gabby Petito returned to Florida to “empty a storage unit” fave days after the pair got into a fight in Utah.

Attorney Steve Bertolino told Newsday that Laundrie flew from Salt Lake City to Tampa on 17 August before rejoining Ms Petito on 23 August – two days before she last spoke to her family.

Mr Bertolino said the trip was to pick up some items and close a storage unit as they were considering extending the trip beyond their planned end in Oregon in October.

“Brian flew home to Tampa from SLC on 08/17 and returned to SLC on 08/23 to rejoin Gabby,” he added to Fox News. “To my knowledge Brian and Gabby paid for the flights as they were sharing expenses.”
