TAMPA, Fla. -

The autopsy results for a Tampa driver who killed himself and four University of South Florida students in a crash reveal he was drunk. 

The results, released by the Hillsborough County medical examiner's office, show the blood alcohol level of Daniel Morris, 28, was more than double the legal limit. 

His blood alcohol level was 0.20.  The legal limit for the state of Florida is 0.08.  

There was a trace of marijuana also found in his system.

On the morning of February 9, Morris was driving a SUV the wrong way on Interstate 295 when he hit a Hyundai Sonata carrying four students.  The four men were members of the Sigma Beta Rho fraternity.

According to investigators Morris left a party the night before, got into his roommate's SUV and took off. 

Investigators are looking into exactly where he began to travel the wrong way on the interstate. 

The four USF students have been identified as 21-year-old Dammie Yesudhas, 21-year-old Jobin Joy Kuriakose, 20-year-old Imtiyaz "Jim" Ilias and 22-year-old Ankeet Harshad Patel.
