An initial autopsy report has found that a black college football player killed by a police officer had used a synthetic psychedelic drug and marijuana prior to the deadly confrontation at an Arlington car dealership.

Days after a police officer in the Dallas-Fort Worth area city of Arlington fatally shot a young man at a car dealership, Arlington's police chief says that Officer Brad Miller has been fired.

Protesters are calling for criminal charges and police reforms, citing what they call a pattern of violence. Demonstrators held a rally and a march Monday at which people held placards bearing the names of people who have died at the hands of police. Miller, 49, is white; he shot Christian Taylor, 19, who is black.
