MEMPHIS, Tenn. -- There's so much we still do not know about the Michael Brown shooting in Ferguson, Missouri.
Witnesses claim the 18-year-old was appearing to surrender when he was killed.
While other witnesses and police say brown had a confrontation with the police officer and reached for the officer's gun.
A grand jury is weighing whether to charge the officer.
The FBI is also investigating.
