DALLAS – Nearly four years after the tragic abduction and murder of 4-year-old Cash Gernon, the man accused of the crime has been deemed competent to stand trial. FOX 4 is uncovering what this legal development means and how the capital murder case is expected to proceed.
The case dates back to May 2021, when a jogger discovered Cash’s body on Saddleridge Drive in South Dallas. The young boy had been brutally stabbed to death.
“He was the sweetest little boy. He loved everybody,” Cameron Mori told FOX 4 in a 2021 interview.
At the time, Mori’s mother had been caring for Cash and his twin brother after their father left them in her custody. Their biological mother was not present.
Shortly after the discovery, Dallas police arrested then-18-year-old Darriynn Brown, charging him with burglary, kidnapping, injury to a child, and capital murder.
Legal Developments and Mental Competency
Last week, Brown was transferred back to the Dallas County jail after being deemed mentally competent to stand trial. This determination indicates that he has undergone treatment and is now able to comprehend the legal proceedings against him.
However, significant questions remain regarding Brown’s mental state at the time of the crime.
The Role of the Insanity Defense
Defense attorney Heath Harris emphasized that his client’s current competency does not necessarily reflect his mental state when the crime occurred.
“It’s not about his current mental state; it’s about what his mental state was at the time of this alleged offense. We said then, and we continue to assert now, that we believe the insanity defense will be a factor in this case,” Harris stated.
Former prosecutor Toby Shook, who is not involved in the case, explained the legal implications of an insanity defense.
“For the insanity issue, the key question is whether the defendant was legally insane at the time of the crime,” Shook said.
Prosecutors are expected to enlist independent experts to assess Brown’s mental state at the time of Cash’s death.
“In previous cases, if the district attorney’s experts determine a legitimate insanity defense applies, they may acknowledge it. However, this does not mean the defendant is simply released. If the DA’s experts disagree with the defense’s claim, then the case typically proceeds to trial, where both sides present competing expert testimony,” Shook explained.
Next Steps in the Trial Process
Moving forward, prosecutors will review Brown’s treatment history and conduct further psychological evaluations before determining how to proceed.
Judge Stephanie Huff is overseeing the case and is reportedly working to expedite the trial process.
Despite the recent ruling on competency, Harris warned that Brown’s mental state could deteriorate again before the trial begins—if it moves forward at all.
“He is dealing with a mental illness, a mental disease,” Harris said.
As the case continues, legal experts anticipate a rigorous examination of Brown’s mental health history, the circumstances surrounding the crime, and whether an insanity defense will hold up in court.
