Transcript for Looting Amid Protest Over Black Teen Fatally Shot by Police
towns. Martha is standing by. We start with the rioting in a St. Louis suburb after a police officer shot and killed an unarmed teenager. Steve osunsami has the latest and joins us this morning from Ferguson, Missouri. Good morning, Steve. Reporter: Good morning, two things happened last night. One was the protest for the slain 18-year-old. The second was lawlessness that even the young man's family is distancing itself from this morning. There were teams of people hitting up sporting good stores, stealing from automotive stores, and burning gas stations like this one to the ground. Overnight, on fire and out of control. A free for all here. Reporter: North of St. Louis, thieves ruled the night, ransacking local business. Police armed with riot gear couldn't keep up. Watch as people of all ages loot this convenience store and burn it down. It was an entirely different scene from the emotional protest for the slain young man. The night began with a peaceful vigil. He was supposed to start classes this morning at college. They took my son from him. He didn't do anything. Reporter: But instead his mother is planning his funeral. Everything I put into him, they just took that. With no compassion. Reporter: It's not clear what led to the police shooting Saturday afternoon. Brown was walking with a friend to his grandmothers in this predominantly african-american suburb when a police officer drove by and told them to get off the street. He was running, he stopped, put his hands up after he had gotten shot repeatedly. Reporter: But police are telling a different story, saying one fought with the police officer after he stepped out of the vehicle. He was pushed back into the squad car and physically assaulted. It is our understanding that within the police car there was a struggle over the weapon. There was one shot fired within the car. Reporter: Brown was killed in the street 35 feet from the officer's car. Brown was hit more than once. Police confirmed the teen was unarmed. The officer involved in this shooting has been placed on administrative leave. Police have arrested 32 people since this began.
