Question

which detail from Free the Children shows that there were suspicious circumstances surrounding iqbal's final night

Answer 1

And what had happened to the bicycle, which might have shed some light on the shooting? The police had never collected this vital piece of evidence.

Answer 2

It is never made clear what was that happened to the bicycle. It might have been important to clarify what happened during the shooting, but apparently, it was left out, even though it was a very important piece of evidence. It seems that the police didn't even think of investigating in that direction.
