Ferguson police chief Tom Jackson named Darren Wilson, who the chief described as a 6-year veteran of the force with no previous disciplinary action filed against him.
During a press conference yesterday, however, a reporter, citing protesters as the source, asked Jackson whether Wilson was Brown's shooter.
"I'm not going to comment on that," Jackson said.
Though he refused to address the question about Wilson, Jackson specifically said another man - who hacker group Anonymous named as the shooter - wasn't the man responsible.
Jackson had previously said the department wouldn't release the name until "someone is formally charged."
