[5][6] The killings caused a stir both in the city and the entire state after it was found that Brown, a dangerous recidivist, worked as a police informant.
After this arrest, he began to cooperate with investigators in a plea agreement, agreeing to plead guilty in exchange for testifying against other inmates, so that the charges against him would be dropped and he could be released.
In September 2000, Brown was arrested for drug possession and attempting to sell them, but was released yet again after he provided some information on crimes committed in the county.
In March 2015, Brown was recruited by agents of the Bureau of Alcohol, Tobacco, Firearms and Explosives, working as an informant for five consecutive years.
Over the following years, Brown repeatedly violated parole conditions, but each time avoided criminal liability due to his position as an FBI informant.
Two weeks later, he was arrested in Hazel Park for drunk driving but was quickly released on October 29 due to intervention by a Detroit police officer serving on a federal task force.
[11] On January 30, 2020, Brown visited some friends from his youth, 48-year-old Dorian Patterson and his brother Gerald, with whom he drank alcohol.
Late in the evening, a quarrel occurred between the pair and Brown, who proceeded to shoot and kill Green and Patterson, as well as non-lethally wounding Smith, who managed to leave the crime scene and report the incident to the police.
[15] Two days later, 41-year-old Amir Thaxton was shot dead inside his clothing store in Detroit, with his money, valuables, and Caravan stolen after.
Brown attempted to sneak away by moving through houses but was spotted by tenants, after which he was surrounded by law enforcement officers in a backyard.
