So how did Mr. Zimmerman track down Trayvon in the dark when it’s pretty obvious Trayvon could easily outrun Mr. Zimmerman any day.
First, it’s probably not that dark as there are probably street lights available and the kid had a grey hoodie, which would show reasonably well in the dark, under street lights.
Second, Zimmerman knew the gated community and the kid did not. The kid had only been there for a few days and probably didn’t know the layout of the community as well as Zimmerman. Also, and it’s only a guess, the kid was probably trying to find his way home at the time he was trying to get away from Zimmerman. This would allow Zimmerman to catch up to him, as Zimmerman’s focus was catching the kid and not getting away.
