“In the two and a half years since Michael Brown, a black 18-year-old, was shot and killed by a white police officer in Ferguson, Mo., the explosive case has been parsed in intricate detail. Witnesses offered varying descriptions of the fatal encounter. Investigators examined bloodstain evidence on the street where Mr. Brown died. And the police released a security video from a nearby store that showed Mr. Brown pushing a worker and taking cigarillos minutes before the shooting.
“But a second, previously unreported video from that same convenience store included in a new documentary is raising new questions about what happened in the hours before the shooting on Aug. 9, 2014.”
