Prosecutor Robert McCulloch says the records released Saturday were inadvertently not included with documents made public Nov. 24, when a grand jury decided not to charge Ferguson Police Officer Darren Wilson for killing Brown.

Among the newly released records is a transcript of an interview of Brown’s friend Dorian Johnson by the FBI and county police. The interview happened four days after the Aug. 9 confrontation in which the white officer shot the black 18-year-old.

Johnson later testified to the grand jury. A transcript of that testimony was released last month.
