Explaining Gabby Petito's Autopsy Results With a Forensic Expert

This week on The Debrief, Pei-Sze Cheng takes a deep dive into this week's autopsy results in the Gabby Petito case, and talks with the team behind Wondery's The Vanished podcast about why some missing persons cases get more attention than others.

More on the case: Investigators have added a cadaver dog as part of their ongoing, exhaustive search of the 25,000-acre Florida preserve where Gabby Petito's fiancé Brian Laundrie allegedly said he was heading for a hike the day he disappeared, the assisting sheriff's office confirmed to News 4 on Thursday.

The Pasco County Sheriff's Office, which is about an hour and a half drive from the Carlton Reserve, which has been the focal point of the FBI's hunt for Laundrie since he vanished a month ago, said the human remains detection dog was requested.

A spokeswoman said the animal was provided at the request of both the FBI and the local North Port police department. She said her sheriff's office is the only one with that type of dog so it is in high demand, adding that Thursday isn't the first time her office has been asked to assist in this particular investigation.

The intensity of the Carlton Reserve search appeared to ramp up accordingly. NBC affiliate WFLA reported that multiple law enforcement vehicles were spotted on the Venice end of the reserve Thursday morning, marking the first time this week the affiliate's crews had seen activity at that entrance. There was a flurry of renewed activity last week, too, when Laundrie's father assisted in person for the first time.
