"It's probably one of the most horrific things I've ever seen in my whole life," Adam Wright told Eyewitness News.
Wright was driving on Strickland Rd. when he saw Raymond Cook slam into 20-year-old Elena Shapiro's car.
"Her car ended up running right into the railing right beside -- right in front of me," Wright recalled.
While approaching Shapiro's wrecked car, Wright said he was dialing 911. He said Cook ran over to Shapiro's car immediately.
Wright watched as the doctor helped an off-duty EMT perform CPR on the woman.
"He was doing the chest compressions," Wright said. I was standing back still talking to 911."
By the time EMS arrived, it was too late. Police said Cook had been drinking before the wreck, but his the results of a blood alcohol test have not been released.
Wright believes the doctor was drunk.
"I didn't really smell anything, but like I said, I knew that something wasn't right with him," Wright explained. "I really hate that it happened, and I wished that we could have done something more. My heart goes out to her family."
Cook was allegedly driving 85 mph in a 45 mph zone.
He is charged with second-degree murder, careless and wreckless driving while impaired.
