A key witness in the capital murder trial of Kewon White told jurors this week that the timing of Dallas rapper Mo3’s death struck her as “fishy.” Jocylynn Jackson, who had been dating Mo3 and shares two children with co-defendant Devin Brown, testified that the rapper spent the night at her home and was fatally shot on Interstate 35E less than an hour after leaving.
Jackson’s words, delivered in Dallas County court during White’s ongoing trial, quickly drew attention across hip-hop media and local news. She said she
“just knew it was something fishy” and “felt like somebody had something to do with it.”
Her testimony describes her personal suspicion at the time. It does not prove that Brown, White, or anyone else arranged the killing. All three defendants remain presumed innocent.
The artist, Mo3, whose actual name is Melvin Noble, died on November 11, 2020, at age 28. The South Side hip-hop artist, who was signed to Empire and produced songs such as “Broken Love” and “Outside (Better Days),” was traveling in the northbound lane of I-35E in the Oak Cliff section of Dallas during late afternoon. Another car caught up with him. Both cars stopped. A gunman who had a rifle with him got out, pursued Noble as he ran away from his car, and fired shots at him several times. Medical experts confirmed that Noble received 13 rifle shots.
Prosecutors allege the shooting was a murder-for-hire plot. They say White carried it out, Brown assisted, and Dallas rapper Markies Conway, known as Yella Beezy, paid for it amid a long-running public feud with Mo3 that dated to roughly 2017–2018. Conway has pleaded not guilty and denied involvement. White and Brown have also pleaded not guilty. White, already serving a federal sentence on an unrelated gun charge, is the first of the three to stand trial on capital murder charges. His case began with jury selection in late August 2026 and is expected to last about two weeks.
Early testimony has included Jackson, Mo3’s mother Nichole Noble, eyewitnesses who described the chase and gunfire, paramedics, and the retired chief medical examiner. Prosecutors have pointed to surveillance, phone records, and other evidence. Defense attorneys have argued the case relies heavily on circumstantial links and that no witness positively identified White as the masked shooter.
A separate dispute involves rap lyrics. Prosecutors sought to introduce songs such as “Hitters,” “Keep It in the Streets,” and “On Your Head” as evidence of motive and intent. The defense countered that lyrics are artistic expression. The judge allowed limited use of certain tracks.
Jackson’s account places Mo3 at her home the night before the shooting and establishes the short window between his departure and the ambush. Prosecutors still must prove beyond a reasonable doubt that White was the shooter, that a murder-for-hire agreement existed, and that the alleged participants carried it out. The jury will weigh the full record, including cross-examination of Jackson’s relationships and the other evidence, before reaching any verdict.
