"A man who testified in the Amber Guyger murder trial died Friday night after he was found shot multiple times at a Dallas apartment complex, the Dallas County District Attorney's office confirms.
Joshua Brown, a neighbor of Botham Jean's at the South Side Flats apartments and a witness in the trial, died in the shooting, according to the district attorney's office.
Police were called about 10:30 p.m. to the Atera apartments in the 4600 block of Cedar Springs Road, near the Dallas North Tollway and Lemmon Avenue.
Several people flagged the officers down and directed them to Brown, who was on the ground in the parking lot with multiple gunshot wounds, police said."
As for Guyger, yeah it fits better as a manslaughter charge, etc.... But I won't shed a tear, she got off light.
