Prosecutors in the US state of Florida have released almost 200 pages of evidence in the case of Trayvon Martin, the unarmed black teenager killed by a neighbourhood watch volunteer, George Zimmerman, last February.

The documents and images provide some support for both the shooter - who's claimed self-defence - and the boy's family which says the killing was racially motivated and avoidable.
