In the vicinity of New York relatives and friends of the killed Gabrielle "Gabby" Petito said goodbye to the 22-year-old at a funeral service.
The ceremony, which was broadcast live on the Internet, met with great sympathy across the country.
According to the broadcaster Fox35, the mourners gathered around an empty urn because the Federal Police FBI has not yet released the body of the young woman.
Gabby Petito disappeared after traveling across the United States with boyfriend Brian Laundrie.
Her body was found about a week ago in a national park in Wyoming, USA.
According to forensic medicine, Petito was the victim of a homicide.
Petito's father said at the funeral service on Sunday in Holbrook on Long Island near New York that people should not be sad about his daughter's death, but rather take her short, full life as an incentive.
"I couldn't be more proud as a father," said Joe Petito of his daughter.
Her fiancé Laundrie is currently under arrest warrant.
The 23-year-old returned from the trip alone at the beginning of September, initially refused to give evidence of Petito's disappearance and then disappeared himself.
The case has been moving the US for weeks and has also made headlines internationally.
Petito and Laundrie, who lived together in North Port, Florida, set off on a trip across the United States in July in a van converted into a motorhome.
They shared their experiences on the adventure planned for four months on Instagram and Youtube, pictures showed a smiling couple and impressive landscapes.
