Forensic Artist Details How Brian Laundrie's Appearance Will Have Changed

A leading forensic artist has detailed how Brian Laundrie's appearance will have changed since his last confirmed sighting.

Laundrie, who is a person of interest in the death of his fiancée Gabby Petito, was last seen on September 14 entering the vast Carlton Reserve in Florida.

The FBI has issued an arrest warrant for the 23-year-old and the law enforcement search for him continues, with TV personalities such as Dog the Bounty Hunter and former America's Most Wanted host John Walsh lending their support.

Now forensic artist Lois Gibson has said the groups searching for Laundrie need to keep in mind that his appearance will have changed—whether intentionally or not.

Gibson, who set a Guinness World Record in 2017 after her work helped to identify 751 criminals and secure over 1,000 convictions, told Newsnation's Banfield talk show that the stress of the situation would have brought about changes to Laundrie's appearance.

She said: "I've been working cases for 39 years and he is going to get a lot of sun, he's gonna lose weight. I don't care how much money he has. If you're on the run … it's hard to eat, it degrades your life."

Gibson—who also drew the first sketch to feature on an episode of America's Most Wanted, playing a crucial role in solving the case—added that there were some subtle changes Laundrie could make to his appearance in an attempt to evade capture, if he is "smart." These include shaving off his facial hair.

However, the forensic artist said there was one telltale feature that often helped law enforcement find and identify fugitives: their ears.

"Ears are the most complicated object on the surface of the head. They're more complicated than the eyes, lips or the nose," Gibson said.

Crucially, she added, "there's really nothing that can be done to alter them."

Laundrie was reported missing by his parents on September 17 and Petito's body was discovered two days later in Wyoming's Bridger-Teton National Forest. Her death has been ruled a homicide.

This week, Petito's parents made a public appeal urging Laundrie to turn himself in.

There have been multiple reported sightings of him in recent days, including some in Florida, Alabama and even Canada.

One former FBI agent suspects the search teams need to look even further afield. John MacVeigh, a retired special agent, thinks Laundrie may have already escaped the U.S. on a plane or cruise ship.

Newsweek has contacted Gibson for comment.
