Human remains, personal items found during search for Gaby Petito's fiance

Investigators leading a search for the missing fiancé of murdered US blogger have found apparent "human remains" in a Florida park, the FBI has said.

Agents said items belonging to Brian Laundrie, a person of interest in Gabby Petito's death, were also found during the search.

Laundrie has been missing for over a month after returning to Florida from a joint trip without his partner.

Her body was later found in Wyoming, where the couple had been travelling.

On Wednesday, in a news conference, FBI special agent Michael McPherson confirmed that investigators had found "what appears to be human remains" on a search in the Carlton Reserve area.

He said the remains were discovered along with personal items, including a backpack and notebook belonging to Laundrie.
