An arrest warrant has been issued for the partner of murdered US YouTuber Gabby Petito as federal investigators continue their exhaustive search for him.
Twenty-two-year-old vlogger Ms Petito, who was found dead this week, had been travelling with fiance Brian Laundrie when she disappeared.
The FBI in Denver has confirmed Laundrie, 23, is the subject of a warrant in connection with "activities" following Ms Petito's death.
A grand jury in U.S. District Court in Wyoming indicted him on a single count of unlawfully using the bank debit card.
He was not charged in her death.
Special Agent Michael Schneider, who is leading the case, said in a statement on Thursday: “While this warrant allows law enforcement to arrest Mr Laundrie, the FBI and our partners across the country continue to investigate the facts and circumstances of Ms Petito’s homicide.
"We urge individuals with knowledge of Mr Laundrie’s role in this matter or his current whereabouts to contact the FBI.”
The search for Laundrie in the vast Florida wilderness entered its sixth day on Thursday as the mystery deepened around a case that has engrossed America and the world.
A team of divers joined police and FBI agents using boats and helicopters looking for Laundrie in the alligator-infested Carlton Reserve again, a spokesman said.
As of Wednesday night, he said, they had "nothing" to show for their efforts so far.
Authorities have not said why they are convinced Laundrie, whom police quickly identified as a "person of interest" in the case, may still be somewhere inside the more than 24,000-acre (9,700-hectare) wilderness preserve near his home in North Port, Florida, more than a week after he told family members he was headed there to hike alone.
North Port police say Laundrie's parents did not report him missing until September 14, three days after the family last saw him.
The Carlton Reserve has more than 80 miles (128 km) of hiking trails but is dominated by swampy water.
Ms Petito was reported missing on September 11.
Ten days earlier, Laundrie had returned home to North Port without her from a cross-country road trip the couple chronicled in social media posts.
Ms Petito's body was discovered on Sunday in a remote corner of the Bridger-Teton National Forest in western Wyoming, less than 1,000 feet (300 m) from where, on the evening of August 27, another pair of travel bloggers caught video images of the couple's white Ford Transit parked on a dirt road.
In identifying her remains, Teton County medical examiners ruled Ms Petito's death a homicide but did not make the cause of her death public.
Ms Petito and Laundrie left her home state of New York in July, heading west on what they called a "van life" trip. They posted photos to social media as they traveled through Kansas, Colorado and Utah.
Witnesses last saw Ms Petito on August 24 as she left a Salt Lake City hotel. She posted her final photo the next day.
Her family believes she was headed to Grand Teton National Park when they last heard from her. Her body was found at the edge of that park near the Spread River.
Investigators searched the Laundrie family home in North Port last week and were seen loading cardboard boxes into a van and towing away a silver Ford Mustang.
In seeking search warrants, investigators cited text messages from Ms Petito's phone to her mother, Nicole Schmidt, that struck Schmidt as suspicious.
The final text from Ms Petito's phone came on August 30 and read only: "No service in Yosemite," a national park in California that she and Laundrie are not believed to have visited during their trip.
On August 12, a 911 caller reported to emergency dispatchers that Laundrie was slapping and hitting Ms Petito in front of the Moonflower Community Cooperative in Moab, Utah.
Moab police pulled the couple over in their van on a highway near Arches National Park. Body camera footage of that encounter shows Ms Petito sobbing as she describes a fight between the couple that she said escalated into her slapping Laundrie as he drove the van.
The officers did not detain Ms Petito or Laundrie but told them to spend the night apart.
