Mr. Warren served as a prosecutor on the trial team in this first-degree murder and arson case out of the Eastern District of Oklahoma. The trial took place in the federal courthouse in downtown Oklahoma City, Oklahoma, beginning the week of November 16, 2022. Joseph (Joey) Hernandez was accused of a heinous crime. He was accused of killing his own mother and grandmother by covering both propellant and lighting them on fire. Both women were killed and the home they resided in burned to the ground. At trial, the defendant claimed to have accidently set the fire while cleaning tools with gasoline. He asked the jury to find him guilty of Second-Degree Manslaughter for this careless accident, and argued that no one would intentionally burn to death their own mother and grandmother. Mr. Warren directed and cross examined the majority of the witnesses, including three expert witnesses, and delivered both the closing argument and the rebuttal. The defendant was found guilty of murder and arson and later sentenced to life in federal prison.
