Gabby Petito's family say they have not yet received her remains or possessions, which are in Florida where she lived with her missing boyfriend.
The murdered 22-year-old disappeared last month and her remains were found in Wyoming's Bridger-Teton National Forest on September 19.
She vanished during a 'van life' trip through America with her 23-year-old partner Brian Laundrie, who returned home to Florida alone on September 1.
Laundrie later went missing himself, with police naming him a 'person of interest' in Gabby's disappearance.
Gabby's stepdad announced on Tuesday that relatives had not yet received any of her belongings from Florida, the Independent reports.
The family added that Gabby's remains will stay in Wyoming while the investigation is underway.
Meanwhile, Dog the Bounty Hunter claimed Laundrie and his parents stayed at a Florida campsite near their home twice in September.
Dog - real name Duane Chapman - joined the search for Brian last week after he was reported missing by his parents on September 17.
The bounty hunter says he has been inundated with tips and potential clues to the missing man's whereabouts.
The FBI are leading the case to find him and have been searching in a reserve five miles away from his home which is well known for being home to alligators.
Following tweets released by the bail bondsman's daughter, Lyssa, on Monday, Dog has gone public with his alleged findings.
Lyssa wrote: "I can CONFIRM @DogBountyHunter has a HOT lead on Brian’s location. Dad has alerted the proper authorities. Say a prayer guys. This could be it."
She urged the public to keep their tips coming in and said that they had by no means caught him.
Talking to Fox News, Dog said that he believed he had located a camp site where Brian and his parents had stayed in early September, after he returned from his fateful cross-country trip with his partner.
He said that he had been told the family had spent the night in Fort De Soto Park near St Petersburg, which is 75 miles north of their North Port home.
Dog went on to claim that the family had been to the spot with their son twice in early September.
"They were registered, went through the gate. They're on camera. They were here," he said.
"We think at least if he's not here right now, we are sure he was caught on camera as he went in the gate — that he was here for sure. Not over in the swamp."
He continued: "Allegedly, what we're hearing, is two people left on the 8th.
"Three people came in on the 6th, and two people left on the 8th. I think he's been here for sure."
There has been no comment on Dog's allegations by the FBI.
