(CNN) – Autopsy results have confirmed that the remains found Sunday in the Bridger-Teton National Forest are those of Gabby Petito, a 22-year-old woman who disappeared while on a trip exploring national parks with her fiancé, Brian Laundrie, according to the FBI in Denver.
The FBI tweeted that Teton County Coroner Dr. Brent Blue ruled the manner of death a homicide in his preliminary findings.
“The cause of death remains pending final autopsy results,” the FBI said.
“Anyone with information concerning Mr. Laundrie’s role in this matter or his current whereabouts should contact the FBI,” Special Agent in Charge Michael Schneider said.
The FBI in Denver said the agency would like information from anyone who may have had contact with Petito or Laundrie or who visited the Spread Creek Dispersed Camping Area between August 27-30 or may have seen their vehicle.
Petito’s remains were found Sunday in an undeveloped camping area in Bridger-Teton National Forest on the eastern edge of Grand Teton National Park, officials have said.
Authorities in Florida are searching for Laundrie, who has not been seen in a week.
Petito’s family said through an attorney earlier Tuesday that they need time to grieve.
“We will be making a statement when Gabby is home,” attorney Richard Benson Stafford said in a statement obtained by CNN affiliate KSL.
Search for fiancé continues
The police search for Laundrie continued Tuesday at a Florida nature reserve where his parents reportedly said he indicated he was going last week. Laundrie’s parents told investigators he left their home in North Port with a backpack September 14 to go to the T. Mabry Carlton Jr. Memorial Reserve near Venice.
“A weekend ground search and aerial search Monday of the 25-thousand-acre preserve has yet to yield any answers, but we must press on,” North Port Police said on Facebook. Police indicated the search picked up Tuesday in a different part of the reserve.
It concluded Tuesday evening around sundown and will resume Wednesday, authorities said.
Before his parents told police Laundrie left the home September 14, he had refused to talk to investigators, and the family had directed them to their attorney, police said.
Authorities also have searched the family home, including on Monday. FBI agents removed a number of items from the home Monday, and a Ford Mustang convertible was also towed away.
