Officials: Ala. airport sign falls on family, kills 10-year-old boy, hurts 3 other children

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.
