"The burns are covering 63% of his body," Arthur said. "So it's basically most of his front. His lower legs and his feet are not affected. But the back of his legs and the front of his body, the right side of his abdomen is pretty bad." According to Arthur, Drew has already undergone several surgeries. "It's a process because he's hurt on the front and the back. They could only do one side at a time," he explained. "So they did the front on Monday, and then part of the back on Tuesday. And I understand they're looking at his shoulder more closely tomorrow." Arthur and Debra, Drew's mother, have been with Drew in Arizona and flew back to Hawaii to take care of some business before going back. "We're going to be there for him as he goes through this," Arthur said. Even though Drew is intubated and heavily sedated his mother said he wiggles his toes and nods, so they know he can hear them.
