GAINESVILLE, Fla. (AP) - The Florida Highway Patrol says there was a three-vehicle crash just hours before a series of pileups killed 10 people on the same stretch of Interstate 75.
    
According to the report released Monday, heavy smoke and fog resulted in low visibility along I-75 south of Gainesville late Saturday. About 11:55 p.m. Saturday, a tractor-trailer hit a Toyota in the northbound lanes. A Lexus then hit the back of the truck.
    
Authorities say a passenger in the Lexus was sent to the hospital in serious condition.
    
The Highway Patrol closed I-75 and nearby U.S. 441 a short time later, due to worsening road conditions. But the highway was then reopened early Sunday and a series of pileups began around 3:45 a.m., some of them fatal.
