A lawyer hired by three fans hurt when a NASCAR Nationwide Series race crash hurled debris into the grandstand at Daytona International Speedway will focus his probe on the catch-fencing.

"Our firm has the utmost respect for NASCAR and their fans," Matt Morgan of the Orlando, Florida, law firm Morgan and Morgan, said via Twitter on Tuesday. "Our investigation will look into the manufacture of the fence.

"Our goal, is to ensure this type of tragedy does not occur again. Fans deserve to be protected and safe at sporting events," Morgan wrote.
