An emergency room doctor said he is very concerned about the two people who were the most critically injured when a car plowed into a crowd of revelers at the South by Southwest festival in Austin early Thursday morning.

'They're just going to be getting our very best effort,' said Dr. Christopher Ziebell, emergency room medical director at University Medical Center Brackenridge.

Ziebell said Brackenridge received a total of eight patients overnight, including the man who police said was driving the car that drove into the crowd, killing two people and injuring 23 others.

The suspect, who has not yet been publicly identified, was in constant police custody and was discharged after treatment of minor injuries.

In addition to the two critically injured patients, Brackenridge said three others remain in serious condition and the others were released after treatment.

Ziebell said the hospital was prepared for an influx of patients after initially being notified -- incorrectly -- that a bus had crashed into a crowd.

'We were expecting dozens of injured,' Ziebell said. 'We had a beefed-up staff as the first patients arrived, so we were able to be ready.'

The hospital spokesman said the two critically injured patients had suffered head injuries. 'I have a great deal of concern for them,' Ziebell said.
