A white police officer has been fired after he shot and killed an unarmed black teenager in a car dealership in Texas on Friday.
Christian Taylor, 19, was a star college football player at Angelo State University.
The incident happened two days before the one-year anniversary of the shooting of Michael Brown in Ferguson, Missouri.
Police chief Will Johnson said that rookie police officer Brad Miller shot Mr Taylor after police responded to a call for a suspected burglary at the car dealership.
"This is an extraordinarily difficult case," Chief Johnson said.
"Decisions were made that have a catastrophic outcome."
Officer Miller was still in what police call "field training".
Chief Johnson said there were several instances of bad judgement by Officer Miller that led to his being fired.
Mr Miller's tactical misjudgement in the shooting officially led to his firing, but the fact that Mr Taylor was shot and killed did play a role in the chief's decision, police spokesman Christopher Cook added.
The case may be given to a grand jury but no charges had been filed as of yesterday.
Chief Johnson also said the FBI, cooperating in the case, would "act accordingly if it's determined that a civil rights violation occurred".
