MO3's girlfriend testifies in Yella Beezy trial: he 'really disliked Freddy' — and she's co-defendant Devin Brown's ex

MO3's girlfriend Jocylynn Jackson, who is also co-defendant Devin Brown's ex, testified in Yella Beezy's Dallas murder trial that MO3 'really disliked Freddy.' Phone records showed repeated calls from Brown the morning MO3 was killed. Prosecutors allege a murder-for-hire plot; Yella Beezy and Brown have pleaded not guilty, and Trapboy Freddy is not charged.

MO3's girlfriend Jocylynn Jackson took the stand Tuesday afternoon in Yella Beezy's capital murder trial in Dallas. She told jurors she was only there because she was subpoenaed. Jackson is also the ex of Devin Brown, the third man charged in the case; she has two children with him and started dating MO3 (Melvin Noble) in 2020. She testified MO3 spent the night at her apartment on Nov. 10, 2020, and was ambushed on I-35 soon after leaving the next morning. She said she suspected her address had been leaked, and cellphone records shown to jurors revealed repeated calls from Brown that morning. After the killing she texted Brown, 'On my kids you dead.' Brown fired back denying involvement. Jackson said she knew about MO3's public feud with Yella Beezy and Trapboy Freddy, both of whom she went to school with. On cross-examination, the defense pressed her on whether she told prosecutors MO3 had no beef with Yella. 'I said that he wasn't worried about him and that he really disliked Freddy,' she testified. Trapboy Freddy is on the state's witness list and has not been charged. The defense has argued police had tunnel vision and ignored Brown's personal animosity toward MO3. Yella Beezy, real name Markies Conway, has pleaded not guilty. Brown's trial is set for early November.
