A second suspect has been arrested in the ambush murder of Joshua Brown, a key witness in the Amber Guyger murder trial in Dallas, Texas.
Police say Brown, 28, was shot to death during a drug deal that went horribly wrong on Friday night. He was killed 10 days after he testified against Guyger, a former Dallas police officer who is currently serving 10 years in prison for murdering Botham Jean, 26.
Just 2 days after Guyger's trial ended, Brown was killed by three men who, police say, drove from Alexandria, Louisiana to buy 12 pounds of marijuana from him.
During his testimony, Brown admitted to previously serving time for a felony drug conviction.
The three men met Brown in the parking lot of his apartment complex. An argument ensued and Brown shot one of the men before he was shot twice. Brown was rushed to Parkland Hospital, where he was pronounced dead on arrival.
Police say Michael Mitchell, 32, has been arrested in Brown's murder. Another suspect, Jacquerious Mitchell, 20, is in intensive care in critical condition with a gunshot wound to the chest.
Police are searching for the third suspect, Thaddeous Green, 22, of Louisiana.
Dallas police denied Brown's death was linked to the Guyger trial, and the police department vigorously denied rumors of retaliation or assassination.
During a press conference to announce the arrests, Dallas Police Assistant Chief Avery Moore rebuked "community leaders" for spreading rumors.
Police executed a search warrant at Brown's apartment after his murder. They found 12 pounds of marijuana and over $4,100 in cash.
Brown reportedly feared for his life after he was shot in the foot outside a nightclub in 2017. A friend who was with him was shot and killed.
