Police say the college student who crashed his car through the wall along Bayshore Boulevard in May had drugs in his system.
Michael Agana, 19, died five days after the crash. His car went through a barrier and sank in the bay.
Autopsy results now show USF student had both marijuana and LSD in his system, and the drugs were a contributing factor in the crash.
Agana had spent the day at Busch Gardens with a friend, and he crashed the car shortly after dropping his friend off. No one else was in the car.
