A Strange Accident Scene

The front wheel of the bicycle is off, as if McDavid had been working on it.

"If he's going to work on the tire, why would he put his helmet on top of his own tire? It didn't make any sense." Los Angeles Traffic Detective Nelson Hernandez says. "And why wouild he stop here? In darkness? Why wouldn't he just walk the bike down to the end of the alley where there's light?"

There are other suspicious elements of the case, as well.
