Joshua Brown, the Amber Guyger witness who was gunned down on Friday night in Dallas, was set to testify in a wrongful death lawsuit against the Dallas Police Department when he was killed.
Brown, 28, gave key testimony against Guyger, 31, on day 2 of her murder trial for killing Botham Jean, 26. She was convicted of murder and sentenced to 10 years in prison.
Brown was shot to death 2 days after Guyger was sentenced.
Jean's mother is suing the city, citing the Dallas Police Department for failure to properly train Guyger.
The attorney for the Jean family, S. Lee Merritt, stopped just short of accusing the police of assassinating Brown.
"It is a possibility," Merritt said. "I don't have any evidence other than the timing, but I am not ruling anything out. But what I do know is that Joshua was targeted. This was an assassination. He pulled into his parking lot and he was shot. The perpetrators fled. They didn't steal anything from him."
Witnesses reported seeing a silver four-door sedan speeding out of the parking lot after the shooting.
"This is a kid who had no gang ties, there was no lover's quarrel," said Merritt. "He was an AirBnB host and roofer. All the usual suspects of crime, drugs and sex are simply not there."
