Two suspects in custody, one sought in police officer trial witness slaying

DALLAS (AP) — 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 on 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 on 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 on 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 5.4 kilogrammes of marijuana, 149 grammes of THC cartridges and more than USD4,000 in cash during a search of Brown’s home.

It is unclear how the three men came into contact with Brown or why they would have driven more than 483 kilometres from central Louisiana to purchase marijuana in Texas.

The police announcement comes after rampant speculation regarding Brown’s death, which happened two days after a jury sentenced the white former police officer to 10 years in prison for killing her black upstairs neighbour in a case that sparked fierce debate over race, politics and policing.
