DALLAS — Three Louisiana men are suspected in the killing of a witness who testified at the murder trial of a former Dallas police officer, authorities said Tuesday, cautioning that the killing had nothing at all to do with that trial or case.
One of the suspects, Michael Mitchell, 32, was arrested by federal deputy marshals Tuesday night in Marksville, Louisiana, the Dallas Police Department said in a statement. Mitchell’s nephew, 20-year-old Jacquerious Mitchell, was in critical condition in a Dallas hospital with a gunshot wound. The third suspect, Thaddeous Green, 22, was still at large.
Investigators believe the three men were in Dallas to buy drugs from Joshua Brown , Assistant Chief Avery Moore said at a news conference earlier Tuesday. Moore said Jacquerious Mitchell told police that Brown shot him in the chest after Green and Brown began fighting during the drug deal, and that Green then shot Brown twice.
Green left with Brown’s backpack and gun, police said. Authorities confiscated 12 pounds (5.4 kilograms) of marijuana, 149 grams of THC cartridges and more than $4,000 in cash during a search of Brown’s home.
