"About 10 bodies went flying," Hulton told the newspaper.
The festival will continue because of the thousands of visitors in town, SXSW managing director Roland Swenson said Thursday morning. A spokeswoman for the festival said there would be schedule and venue changes.
"It would cause more problems for people to show up and be turned away than to carry on," he said.
A crime scene unit was still investigating the crash, and Acevedo said earlier Thursday there were no plans to change safety protocols at the festival due to the accident.
"We do these events very well, but you cannot stop a person who rather than face drunk driving charges decides to speed at a high rate of speed, go around a uniformed officer forcing him to run out of the way, then at a high rate of speed show total disregard for the sanctity of human life," Acevedo said.
Acevedo asked witnesses and those who may have taken video to contact police rather than post it on the Internet.
