Botham Jean's neighbor, Joshua Brown, who testified against former Dallas officer Amber Guyger at her murder trial was found shot to death in a Dallas, Texas parking lot on Friday night.
According to the Dallas Morning News, multiple witnesses flagged down police officers on Friday night and reported hearing gunshots at an apartment complex near Dallas' Medical District.
Police found Brown unresponsive with multiple gunshot wounds in a parking lot in the 4600 block of Cedar Springs Rd.
Brown was transported to Parkland Memorial Hospital, where he was pronounced dead.
Brown's apartment was located directly across from Botham Jean's apartment at South Side Flats apartments. Brown testified that he was in the hallway on the night of Sept. 6, 2018, when he heard two voices talking at the same time followed by 2 gunshots.
Guyger had just returned home after working a 13-hour shift when she entered the wrong apartment and shot Jean to death.
Brown broke down and cried when he recalled hearing Jean singing gospel music inside his apartment every morning.
Guyger was convicted of murder on Tuesday and sentenced to 10 years in prison on Wednesday.
Brown's death sparked rumors of retaliation for testifying against the former Dallas police officer.
Lee Merritt, a civil rights attorney who represents the Jean family, said Brown's murder "underscores the reality of the black experience in America."
He said Brown lived in constant fear for his life.
"Brown lived in constant fear that he could be the next victim of gun violence," Merritt wrote on Facebook. "Brown deserves the same justice he sought to ensure the Jean family."
