Dallas police say three Louisiana men were involved in the murder of a key witness whose testimony led to the conviction of Amber Guyger, the ex–Dallas police officer convicted of killing Botham Jean, her unarmed neighbor.
The shooting death of 28-year-old Joshua Brown sparked outcry among people who believed he was murdered for participating in Guyger's contentious murder trial, which captured national attention. But police on Tuesday said his death was the result of a drug deal gone bad.
Police said Jacquerious Mitchell, Michael Mitchell, and Thaddeous Green — all of Alexandria, Louisiana — drove to Dallas to buy drugs from Brown. Around 10:30 p.m. on Oct. 4, they arrived at Brown's building in a silver four-door sedan.
Assistant Chief of Police Avery Moore said that, according to Jacquerious Mitchell, Green got out of the car and proceeded to get into an argument with Brown, which escalated into a physical fight. Jacquerious Mitchell got out of the car and Brown "ordered him back into the vehicle" and then shot him in the chest, causing him to fall back into the car. Green then allegedly shot Brown twice in the lower body.
