Brian Laundrie‘s autopsy has come back inconclusive and his remains are now being transferred to an anthropologist, his family’s lawyer says.
On Sunday, attorney Steven Bertolino told PEOPLE that “no manner or cause of death was determined, and the remains were sent to an anthropologist for further evaluation.”
Bertolino also said that Laundrie’s “remains will be cremated and there will be no funeral service.”
The news comes two days after partial human remains were discovered in Myakkahatchee Creek Environmental Park — near Laundrie’s last known location — and one day after dental records confirmed they belong to the 23-year-old fugitive.

Authorities have determined the 22-year-old Long Island, N.Y., woman died from strangulation while on a two-month-long, cross-country road trip with Laundrie.
Laundrie was named a person of interest in Petito’s disappearance on Sept. 15. For the first week of Petito’s missing persons investigation, the Laundrie family refused to cooperate with authorities, directing all questions to their attorney, police said.
A week after the Petito case began, the Laundrie family spoke to the FBI for the first time — but not to talk about Petito.
Instead, Laundrie’s parents wanted to alert investigators that their son, too, had gone missing. They claimed he was last seen on Sept. 13, after allegedly leaving their home to hike in the nearby Carlton Reserve.

The FBI and local Florida authorities quickly launched a search for Laundrie in the 25,000-acre nature preserve, wading waist-deep through snake- and alligator-infested swamps in some areas (The Carlton Reserve is connected to the Myakkahatchee Creek Environmental Park, where his remains were eventually found).
A notebook and backpack were located near Laundrie’s body, in an area of the park previously submerged under water three feet deep.
On Friday, Bertolino told PEOPLE that Laundrie was visibly “upset” the last time that his family saw him.

“Yes, Brian was upset when he left and he was not able to be persuaded not to leave the house,” Bertolino said.
Laundrie was never charged with Petito’s death or disappearance, and a suspect for those crimes has not yet been named.Internet Explorer Channel Network
