A law enforcement official says that the shooter in the Trayvon Martin case will be charged with second-degree murder and is in custody.

The official with knowledge of the case says that the charge
against 28-year-old George Zimmerman will be announced at a news
conference Wednesday evening.The official says he's in custody
in Florida but wouldn't say where. The official spoke on condition
of anonymity because he wasn't authorized to disclose the
information.

An arrest had been delayed because of Florida's so-called stand
your ground law, which gives people wide latitude to claim
self-defense in a killing and other altercations.

The lack of an arrest in the 17-year-old's death had sparked
outrage and rallies for justice in the Orlando suburb and across
the country.
