1 Arrested, 2 Other Suspects Identified in Shooting Death of Joshua Brown

The key witness in the Amber Guyger trial was gunned down Friday night.

One person has been arrested and two other suspects are being sought by authorities in the shooting death of Joshua Brown, Dallas police announced Tuesday.

All three suspects are from Alexandria, Louisiana, and came to Texas to buy drugs from Brown, said assistant chief Avery Moore at a press conference. Jacquerious Mitchell, 20, has been arrested and will be charged with capital murder, Moore said. 

Arrest warrants have been issued for Michael Mitchell, 32, and Thaddeous Green, 22, authorities said.

Brown, 28, was found lying in an apartment parking lot, bleeding from multiple gunshot wounds on Friday night, just days after former Dallas police officer Amber Guyger was convicted of murder in the shooting death of a man whose apartment she said she had accidentally entered, thinking it was her own.

Brown was a key witness in the trial, and testified about noises and voices he heard in the hall after Guyger fatally shot Botham Jean, Brown's neighbor.

Brown shot Mitchell in the chest, after the two argued during a marijuana buy, authorities said. Green then allegedly shot Brown two times, Moore said. The shootings occurred less than 6 miles from where Jean was killed. 

Mitchell is hospitalized with gunshot wounds.

The other two suspects also face capital murder charges, Moore said. Police searched Brown's apartment after his killing and found 12 pounds of pot and about $4,000 in cash, he said.

Since news broke of Brown's killing, speculation swirled about why he was killed, with some blaming the Dallas Police Department. "I assure you that is simply not true," Moore said Tuesday.
