Mario Marquez, Appellant v. the State of Texas, Appellee

Summary

The Court of Criminal Appeals of Texas affirmed Mario Marquez's capital murder conviction and death sentence, rejecting all of his twenty‑eight asserted errors, including requests for lesser‑included offense instructions, limiting instructions on punishment evidence, the use of handcuffs during the penalty phase, and the admission of video evidence. The Court held that the trial court acted within its discretion and that the statutory and constitutional standards were satisfied.
