Johnson was with Michael Brown the day he was shot dead in Ferguson.
Dorian Johnson also was with Mike Brown when he robbed the local convenience store.
The key witness in the shooting of unarmed black teenager Michael Brown was arrested for lying to cops three years ago and currently has an outstanding arrest warrant.
Dorian Johnson, 22, was arrested by police in Jefferson City, Missouri, in June 2011 after he allegedly stole a delivery package off a doorstep in an apartment complex. He was attending college at Lincoln University in the city, which is about 120miles west of Ferguson.
When cops asked Johnson for his name, he told them he was Derrick Johnson and that he was 16 – though he gave officer a birth date that would have made him 17, according to an arrest report obtained by MailOnline.
Officers later found a student ID in Johnson’s sock that gave his real name.
He was charged with misdemeanor theft and filing a false police report. He pleaded guilty to the latter charge. When he didn’t show up to court to answer the theft charge, a judge issued a warrant for his arrest.
