Prosecutors' Broken Deal at Center of Murder Conviction Challenge

Karmelo Anthony's attorneys filed motions July 6, 2026, seeking a new trial and Judge John Roach's recusal in the Frisco stabbing case. The core claim: prosecutors reneged on an off-the-record agreement to exclude character evidence about both teens, then used that threat to coerce Anthony into waiving his right to testify. The defense also contests jury instructions on self-defense. Absent documented proof of the unwritten deal, courts typically favor the prosecution in such disputes.
