Sorry Christo, I hadn't realized you saw it yourself.
OK, so with regard to the red shirt, we have two possibilities:
1. The kid saw a red shirt, told the police and reporters he saw a red shirt, and has now been pressured by his mom and others to change his story.
2. The kid wasn't sure what he saw because it was too dark, but was convinced by the police that he saw a red shirt, and, once having agreed to this, told the reporters the same. But now he realizes that the police manipulated him and he's back to his original stance, that he couldn't tell one way or another.
Who the heck knows? But I'm skeptical of #1, only for the reason that it was too dark to see.
