Authorities said it appears the driver of the vehicle lost control, left the roadway, and rolled over several times. 

Gonzalez said they believe speed may have been a factor in the crash as witnesses reported that the vehicle may have traveling 80 to 85 miles per hour and was attempting to exit the roadway.
