A jury hearing in Bexar County examined testimony and surveillance evidence in the case against Mariano Rendon, who faces aggravated-assault allegations stemming from a brawl at Joe’s Volcano.
Prosecution and defense witnesses gave conflicting accounts of how a violent encounter unfolded on the club’s dance floor. Witnesses described a security guard, Anthony, being overpowered by multiple people while other staff and porters attempted to intervene. Several witnesses testified they saw wrestling, people “jumping on” a man and a tug of war over a radio and a drink. One witness (Tina Jimenez) acknowledged on cross-examination that she told the defendant in a recorded phone call, “He had a little more to drink. It was his birthday,” language the defense used to undercut claims the victim was severely intoxicated.
Surveillance video entered at trial shows portions of the incident; the prosecution played excerpts that it said captured a security guard being struck or kneed while on the ground. Defense witnesses—including porters and staff who were working the night of the incident—told the jury they did not personally see a knee strike and said the footage shown in court was not the full recording of the event. The judge permitted the short clips to be played for witnesses and the jury while the defense argued that portions of the video and longer recordings were not shown.
Why it matters: The dispute over what the video does and does not show and differences in witness recollection are central to whether the jury will find the defendant guilty of aggravated assault causing serious bodily injury. The case turned on credibility, the completeness of surveillance footage and witness memory of chaotic events that occurred months earlier.
What witnesses said: Testimony documented the chaotic, physical nature of the altercation: one porter described three men on top of the security guard and said the situation felt dangerous because the guard carried a firearm. The defendant’s recorded phone conversation with a witness—the defense showed portions in court—was used to show inconsistency in the witness’s memory about how intoxicated the victim was.
Courtroom procedure: The judge managed objections over admissibility and sequencing of audio and video evidence and instructed witnesses not to discuss testimony outside of counsel. The jury was taken out briefly while the court resolved evidence-handling logistics. Multiple photos of the security guard’s injuries were admitted without objection and published to the jury.
Next steps: The trial will continue with additional testimony and exhibits; jurors will ultimately assess whether the defendant’s conduct meets the elements of aggravated assault and whether that conduct caused the serious injuries the state alleges.
Quotation in context: On cross-examination, one witness admitted after hearing recorded audio, “Yes. I did” make the statements about the victim’s drinking that the defense played to the jury.
