A funeral will be held Sunday from noon to 5 p.m. at Moloney's Holbrook Funeral Home, with the service open to the public.
The family has also given its blessing for the media to be there.
Moloney Funeral home will be taking extraordinary measures to preserve the privacy of the family and friends of Gabby Petito at Sunday's funeral service. The Suffolk County Police Department will have extra resources for traffic and safety.
Petito, 22, was reported missing September 11 by her parents after they she did not respond to calls and texts for several days while on a cross-country road trip with fiance Brian Laundrie, who is considered a person of interest in her death.

Laundrie remained missing Friday, with an active warrant for his arrest related to activities following Petito's death.
The U.S. District Court of Wyoming issued the warrant and indictment, alleging unauthorized use of a Capital One debit card and pin code with "intent to defraud."
Petito's body was discovered Sunday at Grand Teton National Park in Wyoming, and a coroner ruled her death a homicide.
The search for Laundrie continues in a massive reserve that includes thousands of acres of forbidding, swampy subtropical terrain replete with alligators, snakes, turkey, deer and other wild creatures.
There are more than 100 miles of hiking and horseback riding trails.
