“I didn’t cry the whole way here. I didn’t cry last night when I heard. I didn’t cry at all, until I seen it, and it was real,” said childhood friend Nakia Hughes. “That’s sad, because we are too young. We are only 17.”

Josh Perry witnessed the crash, and said it’s one of the worst he’s ever seen. It was so bad, he didn’t think it was possible for anyone to have survived.

“One of the police officers told me that we should get inside, and stay inside, because somebody had run from the accident scene, which is crazy, because it didn’t look like anybody would have gotten out, and walked out of that car,” Perry said.

Police said the driver was speeding, and alcohol was a factor in the crash.
