FERGUSON, Mo. (AP) — Family and friends of a Missouri teenager fatally shot by a police officer describe Michael Brown as a quiet, respectful and nonviolent youth.

The 18- year-old had planned to start college this week for a career as a heating and air conditioning engineer. Instead, his parents are planning a funeral after Brown was killed Saturday while walking down the street near the apartment where he lived with his grandmother.

Police say the shooting followed an altercation after the officer told Brown and a friend to move to the side.

Brown's family and friends say he typically shied away from confrontation. His father says Brown was funny and silly, and could solve any problem and bring people together.

A witness said Brown had his hands up when he was repeatedly shot.
