A young girl whose remains were found last year on a Texas roadside may have been from southeast Arizona.

The child’s remains were found in a briefcase left along Interstate 45 in Madisonville, Texas, in September 2016.

On Thursday, the National Center for Missing and Exploited Children and Madison County Sheriff’s Office issued a rendering of the girl’s appearance based on a CAT scan of her skull.

Authorities believe the girl, who was between 2 and 6 years old, would have likely needed professional medical care throughout her life.

The center said the girl was wearing a pink dress, a diaper and had a feeding tube. She appeared to have a condition called micrognathia, meaning she was born with an undersized jaw that would have affected her ability to eat on her own.

The center said officials think the girl could have been from southern California or New Mexico, but Arizona is the most likely. That’s because of a pollen analysis suggesting she was from the southwest U.S. or the adjacent region in Mexico.

The National Center for Missing and Exploited Children urges anyone with information about the girl to call 1-800-843-5678.
