MIDDLETOWN, Del. — Delaware State Police say a driver who was injured in a chain reaction crash has died.

Troopers said in a news release that 85-year-old Robert L. Stevens died Thursday at Christiana Hospital, where he was taken after the Nov. 2 crash.

The other drivers were not hurt. At the time of the crash, troopers charged the driver of the truck with following too closely.

The crash remains under investigation.
