Amber Guyger Case: Slain Witness Joshua Brown's Ex Asks for Prayers Ahead of Son's 1st Birthday

Joshua Brown, the man who was murdered after testifying in the Amber Guyger murder trial, was a father, and now his ex is asking for prayers as their son turns one in a few weeks.

Brown was shot to death days after he testified in the trial of former Dallas cop Guyger, who has since been convicted of killing her neighbor Botham Jean.

Brown’s ex and mother of his child has now taken to Twitter with an emotional plea. Sharing photos of the late man and their son, she wrote:

"My son just lost his dad 3 weeks before his 1st birthday. Keep our baby boy in your prayers please. WE NEED ANSWERS AND WE NEED JUSTICE!!! #JusticeForJoshuaBrown #RestEasyKing"

The ex also shared a video of Brown spending some time with their little boy and described him as a "good father."

Brown, who lived in the same apartment complex as Guyger and Jean, was shot to death on Friday, October 4, at his Dallas apartment complex, CBS News reported.

Still To Come: Brown "made it clear he had no interest in testifying in open court in that trial"

According to the outlet, Dallas police said Brown was fatally shot around 10:40 pm, and several witnesses noticed a silver four-door sedan fleeing the scene.

On September 24, Brown, a prosecution witness, reportedly testified that he heard what sounded like two people "meeting by surprise," followed by two gunshots.

He said he did not hear any police commands like "show me your hands" but clarified that he couldn’t be sure because he couldn’t make out what the two people – Guyger and Jean – were saying.

Brown continued, saying that he then saw Guyger come out of Jean’s apartment into the hallway where she was pacing and speaking on the phone. Guyger was eventually found guilty of murder and sentenced to 10 years in prison.

An attorney for Brown’s family, Lee Merritt, told CNN that the 28-year-old had been serious about keeping a low profile and only reluctantly agreed to testify in the Guyger case. Brown was reportedly targeted in a Dallas strip club shooting last year and had been trying to lay low ever since.

Brown "made it clear he had no interest in testifying in open court in that trial," Merritt said. "I think he had some apprehension about being seen as an informant or a snitch."

Dallas Mayor Eric Johnson has assured via a tweet that "the Dallas Police Department will conduct a thorough investigation into the death of Joshua Brown."

"Until we know more about this incident, I encourage everyone to refrain from speculation," Johnson added.

Brown was a student of interdisciplinary science at the University of South Florida, where he also played football.
