DOVER, Del. (AP) — Police say a car was rear-ended on a Delaware highway, causing a chain reaction that left one person dead.

The News Journal of Wilmington reports Delaware State Police say 44-year-old Catina Isaacs died in the Dover crash. Police say traffic on the highway was backed up for nearly half a mile (.8 kilometers) Friday afternoon and someone crashed into the back of the car Isaacs was driving.

Police say the force then shoved Isaacs' car into a UPS truck, which then hit another car that hit another car. The last few cars came to controlled stops. The UPS truck ran into a ditch. Isaacs' car and the one that crashed into her came to controlled stops, and neither driver was a seating belt. Police say impairment doesn't appear to be a factor.
