Sarasota County Sheriff Kurt Hoffman in a statement during a panel with law enforcement leaders said he believes Laundrie died by suicide.
Hoffman said Laundrie went out to the nature reserve where his remains were discovered and "by all accounts probably committed suicide,” the Herald-Tribune reported Saturday.
Laundrie's cause of death has not yet been announced.
His remains were found by law enforcement in the Carlton Reserve in Sarasota County on Wednesday, Oct. 20.
Laundrie's parents had reported their son missing on Friday, Sept. 17, saying they hadn't seen the 23-year-old in days.

Laundrie had been named a person of interest in the homicide of his 22-year-old fiancée, Gabby Petito, of Blue Point in Suffolk County.
Petito went missing in August while traveling across the country with Laundrie in her van.
On Wednesday, Sept. 1, Laundrie returned to his parents' home in Petito's van, without his missing fiancée.
Her family reported her missing on Saturday, Sept. 11, and her remains were found eight days later in a Wyoming nature reserve.
The Teton County coroner said she was strangled to death.
