This was just written on the nbc4 comments area I know a young woman who heard two downshifts of a motorcycle and then the crash. She didn’t see the crash, she heard it from her open apartment window. Interestingly enough, she didn’t hear roaring crotch rockets, she heard downshifting. I firmly believe you can’t come from “NOWHERE” at this intersection. Even if they were going a 100 miles an hour, the driver would have seen them if she were looking. Perhaps they blended in to lights farther down the road, they aren’t as easy to see as a car. I don’t believe they were racing.
