Brian Laundrie was a person of interest in the disappearance and death of his fiancée, Gabby Petito.

On October 20, his skeletal remains were found in the Carlton Reserve more than a month after he disappeared, while Petito’s remains were found on September 19, her death was ruled a homicide by manual strangulation.

Now, Steven Bertolino, the lawyer representing the Laundrie family, said that the forensic report of Brian’s remains is expected by the end of November.

In an interview with Fox News, Bertolino said that he believes that the forensic anthropologist’s analysis will be done within two to three weeks.

Bertolino said that the forensic results would likely reveal Brian’s time of death. But when he was asked if it would reveal the cause of death, the lawyer said: “we’ll see.”

The authorities discovered Laundrie’s skeletal remains a day after the Carlton Reserve in Florida reopened to the public, The Independent reports.

According to the police, the water levels in the swamp had previously hidden the remains. October has been relatively dry, which made the waters subside, revealing both Brian’s human remains, a dry bag as well as a notebook believed to be his.

Moreover, reports said that investigators found teeth in a skull among the remains in the swamp. Using his dental records, the remnants were later confirmed to be of Brian Laundrie’s.

While the identity has been verified, the Sarasota County medical examiner said they could not determine the time or cause of his death, and instead forwarded the skeletal remnants to a forensic anthropologist for further examination.

Moments after the remains were identified, Brian’s parents and sister, Cassie, took two days to mourn him in private.

Meanwhile, the police said that Brian’s retrieved notebook “may be salvageable” despite being submerged underwater for about a month. They believe that the notebook may give insights about his disappearance or information about his and Petito’s relationship prior to her passing.

However, Petito’s father, Joe said that he doesn’t believe that the notebook would bring him any comfort or closure in the wake of his daughter’s untimely death.
