Owens is in custody after being released from the hospital and faces two counts of capital murder and 23 counts of aggravated assault by vehicle.
David Minick attended the festival this year, but left on Monday. However, he said that many of his friends were still there during the incident.
"Tons of my friends are at South by Southwest right now and everyone is on social media posting a general 'I'm ok, my crew is ok' and 'awful what happened', but it's been interesting to see a lot of people putting out condolences and sending out the word through social media that everyone is fine."
He also spoke about the drinking culture of SXSW.
"That area is packed this time of year, and there is a lot of drinking going on and a lot of free alcohol which is different from other festivals," Minick said. "For the most part I feel people are very responsible and taking cabs or walking. it sounds like this guy totally freaked out, ran from the cops and really screwed up."
