Investigators were working Tuesday to figure out if the student who died in a Monday morning fire at Saddleback College may have started the blaze, officials said.

The student, a 21-year-old man whose name hasn't been released, died from burns at 7 p.m. Monday, about 12 hours after the blaze was reported in a third floor lecture hall, Orange County Fire Authority Capt. Jon Muir said.

After discovering accelerant at the scene, investigators labeled the blaze arson, but "they're still not sure if it was the victim who started the fire," Muir said.

Muir later told the Los Angeles Times that he suspects the student did start the fire.

The student was the only person found in Business/General Studies classroom 356, where the blaze erupted, the Orange County Register reported.

He suffered third-degree burns and was taken to Mission Hospital, then transferred to the Grossman Burn Center in Santa Ana.

The blaze was reported around 6:40 a.m., about 20 minutes before a social psychology class was scheduled to begin in the classroom, college spokeswoman Jennie McCue said. The victim was enrolled in the class, she said.

He had a 3.23 GPA and had enrolled in 11 units last spring. He appeared to be planning to transfer, McCue said.

"The classes he was taking were generally transferable," she said.

The fire broke out near an air-conditioning unit inside the room, and the entire building filled with smoke, officials said. Nearby rooms were also damaged, but firefighters said the school could reopen the building's first floor.

The fire caused an estimated $400,000 in damage, about half of it structural, Muir said.

Classes on the second and third floors of the building have been relocated. Click here for a list of relocated classes.
