Luis Gerardo Lugo Pena was sentenced to 15 years in prison after a jury found him guilty of aggravated robbery for attacking 77-year-old Miguel Martinez Aguirre on September 29, 2023, during a carjacking on Juan Balli Road in Hidalgo County. The incident occurred when two men emerged from a brush area, with one standing in front of Aguirre's light blue Honda and another approaching the driver's side to assault him before stealing his vehicle. Pena was connected to the crime through witness testimony, surveillance footage from an auto parts store, and a recorded confession to police.

The three-judge panel rejected Pena's argument that the 206th District Court erred by failing to conduct a hearing under Texas Code of Criminal Procedure Article 38.22 to determine whether his statement to police was voluntary. Writing for the court, Justice Silva explained that even assuming error, 'Pena's statement was largely cumulative of all the properly admitted evidence considered by the jury.' The court noted that witnesses had already testified about Pena's possession of the getaway van, his presence at the crime scene, and his flight from police, making his confession largely redundant.

Justice Silva emphasized the strength of the circumstantial evidence, writing that 'the jury was able to consider all such evidence and could have made reasonable inferences concerning Pena's involvement in the aggravated robbery.' The court highlighted that Detective Hector Castillo found Pena 'hiding behind the door' at his common law wife's home in Edinburg, where officers also located the victim's stolen Honda. Additionally, surveillance footage from Advance Auto Parts confirmed Pena's presence at the store earlier that morning, linking him to a receipt found in the abandoned van.

The case reached the appeals court after Pena was convicted following a three-day trial in April 2024 before the 206th District Court. During the proceedings, defense counsel raised voluntariness concerns about Pena's recorded statement in Spanish to Detective Castillo, but District Judge denied the request for a hearing outside the jury's presence. The prosecution presented testimony from 12 witnesses and admitted over 100 exhibits, including dash camera footage showing a white vehicle pursuing Pena's van with a flat tire moments before the robbery.

Pena's defense team argued that he was deprived of a potential jury instruction under Article 38.22 regarding the voluntariness of his statement, but the appeals court found no evidence suggesting the confession was involuntary. Justice Silva noted that the recording showed Detective Castillo properly advised Pena of his Miranda rights in Spanish and that 'without any apparent coercion, Pena agreed to waive his rights and to discuss his alleged offense.' The court added that Detective Castillo testified he would not have conducted the interview if he suspected Pena was under the influence of substances.

The panel also rejected Pena's ineffective assistance of counsel claim, finding that his attorney adequately raised the voluntariness issue during trial. Justice Silva wrote that 'a specific request for a hearing was not necessary and raising the issue of voluntariness before the trial court admitted Pena's statement was sufficient to invoke the issue of voluntariness under Article 38.22.' The court applied the strong presumption that counsel's conduct fell within reasonable professional standards, particularly given that no evidence supported suppression of the statement.

The decision reflects Texas appellate courts' willingness to find harmless error when confessions are supported by substantial independent evidence. Justice Silva concluded that the court had 'fair assurance that any error in allowing the jury to consider Pena's recorded statement without an Article 38.22 instruction was harmless or had but a slight effect on the jury's verdict,' given the overwhelming circumstantial evidence of guilt.
