DAYTONA BEACH, Fla. - A second person thrown from a motorcycle in a fiery accident has died.

Jessica King, 23, died from her injuries Thursday afternoon. She was a passenger on a motorcycle driven by 26-year-old William Welch.

Welch was killed when the motorcycle was hit by a car making a turn onto Nova Road near Ridgecrest Drive in Daytona Beach.

Police estimate Welch was doing 20 miles over the speed limit when 20-year-old Bianca Dauro failed to yield the right-of-way.

Authorities said Welch was wearing a helmet, but King was not.
