One of three suspects remained at large Wednesday in the death of Joshua Brown, a key witness in the murder trial of former Dallas police officer Amber Guyger, who was convicted of killing a neighbor in his own apartment, USA Today reports. Deputy Police Chief Avery Moore said Brown was killed in a drug deal that ended in a gun battle. Brown was found shot to death in a parking lot Friday, two days after Guyger was sentenced to 10 years in prison for last year’s fatal shooting of Botham Jean. The accountant was eating ice cream in an apartment Guyger mistook for her own.
Michael Mitchell, 32, was arrested by federal deputy marshals in Marksville, La. His nephew, 20-year-old Jacquerious Mitchell, was in critical condition in a Dallas hospital with a gunshot wound. A manhunt was underway for Thaddeous Green, 22. Moore said Jacquerious Mitchell told authorities he, his uncle and Green had gone to Dallas from Louisiana to buy drugs from Brown. An argument ensued, however, and Brown was shot. Moore said 12 pounds of marijuana, other drugs and $4,000 were seized from Brown’s apartment. The NAACP Legal Defense and Educational Fund and some community leaders had called for an independent investigation into Brown’s death. His testimony was crucial because he lived on the same floor as Guyger and heard her talking to Jean.
