Three suspected in Dallas witness’ death

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.

The suspects — Jacquerious Mitchell, 20; Michael Mitchell, 32; and Thaddeous Green, 22 — are from Alexandria, La., and investigators believe they were in Dallas to buy drugs from Joshua Brown, Assistant Chief Avery Moore said at a news conference. 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.

Jacquerious Mitchell is in a Dallas hospital in “critical condition,” police said. Neither Michael Mitchell, who is Jacquerious’ uncle, nor Green are in custody.

Authorities confiscated 12 pounds of marijuana, 149 grams of THC cartridges and more than $4,000 in cash during a search of Brown’s home.

The announcement comes after days of speculation regarding Brown’s death, which happened two days after a jury sentenced former police officer Amber Guyger to 10 years in prison for killing her upstairs neighbor, Botham Jean. Guyger fatally shot Jean in his fourth-floor apartment, which she said she mistook for her own unit one floor below.

Brown, who was black, was one of several neighbors who were called by prosecutors to testify at the trial.
