TAMPA, Fla. (AP) - An autopsy has revealed that a Tampa man who killed four people and himself while driving the wrong way on a Florida highway had more than twice the state's legal limit of alcohol in his system.
    
The Hillsborough County Medical Examiner's office released the autopsy report Monday for 28-year-old Daniel Morris.
    
The crash happened on Interstate 275 in Tampa on Feb. 8. Morris' SUV was going the wrong way and hit a Hyundai Sonata, which was carrying four University of South Florida members of the fraternity Sigma Beta Rho.
    
The autopsy report showed that Morris had a blood alcohol level of 0.20 percent. State law considers a driver impaired at 0.08.
    
The report also said Morris had a trace of marijuana in his system.
