A coroner says one of four children injured when a sign fell at an Alabama airport has died.
The sign fell in the newly renovated Birmingham-Shuttlesworth International Airport terminal Friday afternoon. Officials say four children and their mother were injured.
Jefferson County Deputy Coroner Derrick Perryman says a 10-year-old boy later died.
Birmingham Fire and Rescue Battalion Chief Donald Jones tells WBRC-TV he estimates the sign weighs between 300 and 400 pounds.
Airport spokeswoman Toni Herrera-Bast says officials aren't sure how the sign fell and are investigating.
The airport completed the first phase of a more than $201 million modernization effort and opened newly renovated concourses last week.
