The victim was inside a Dodge pickup truck that crashed into a tractor trailer as it traveled south early Sunday, authorities determined Tuesday. The driver and another passenger in the pickup had not been identified early Wednesday. The Highway Patrol on Tuesday released the name of an eighth person killed in the crash. The name of a passenger who died in her car has not been released. The road was reopened about three hours later after the Highway Patrol determined conditions had improved. While Florida officials said they are willing to review their protocols in determining when to shut down - and reopen - a major highway. The Highway Patrol was also quick to point out that motorists must be prepared to quickly make good decisions because road conditions can change quickly. Officials said the decision to close a road is made by a Highway Patrol supervisor, who relies on feedback from troopers who assess road conditions. They use information and forecasts from the National Weather Service. A key piece of information is an index estimating the humidity and smoke dispersion on a scale of 1 to 10. If the score is 7 or higher, the Highway Patrol's protocol is to close the road. The index score for early Sunday had been forecast to be a 6 in the four-county region that includes the crash site, according to the National Weather Service. Investigators continued piecing together details from Sunday's crash. The remaining bodies were so badly burned that dental records and vehicle identification numbers may have to be used to get positive identifications. Another daughter remained in the hospital with serious injuries.
