LAREDO, Texas — Rene Mendez was found guilty of capital murder after a jury determined he was responsible for the deaths of Brianna and Sylvia Ramos in March 2023. The verdict came on the fifth day of proceedings in the 341st District Court, where assistant district attorneys detailed a harrowing timeline of events leading up to the tragic murders.
During closing arguments on October 24, 2025, Assistant District Attorney Francisco Vigil outlined the case against Mendez, recounting the circumstances surrounding the deaths. He revealed that the women were last seen alive on March 5, 2023, when they were discovered missing by family members the following day. Evidence indicated a violent scene, with Mendez’s DNA found at the crime scene and a confession in which he expressed remorse over his actions.
Vigil characterized Mendez’s actions as a consequence of his addiction to drugs, stating that the defendant’s destructive behavior led him to commit these violent acts. “What he did wasn’t an accident,” Vigil asserted, highlighting that the brutality of the killings indicated a deliberate intent. He recounted testimony from forensic experts who confirmed that Brianna’s death resulted from manual strangulation, suggesting a premeditated attack.
The prosecution presented video evidence indicating that Mendez was the only individual to leave the apartment alive, strengthening their case. Vigil emphasized that the confession revealed specific details, including Mendez describing a knife and his ambush on Sylvia upon her return from work.
The defense took a different approach, arguing that the police had mishandled the investigation and violated Mendez’s rights. Defense attorney Fred Trevino claimed the evidence against his client was inappropriately obtained, attempting to undermine the prosecution’s case by questioning the legality of the confession and asserting that Mendez was not in a proper mental state during questioning.
Trevino portrayed Mendez as a man overwhelmed by addiction rather than a cold-blooded murderer. He argued that the timeline of events suggested a chaotic sequence rather than a premeditated plan, asserting that the defense did not need to prove innocence but rather just raise reasonable doubt to avoid a capital murder conviction.
Assistant District Attorney Kassandra De Hoyos subsequently took the stand, emphasizing the gravity of the choices Mendez made on the day of the murders. “Addiction does not justify murder,” she stated, describing the psychological toll the crimes would take on the families involved. She mimed the act of strangulation for the jury, reinforcing the intentional nature required for a capital murder charge.
As the trial neared its conclusion, emotionally charged testimonies underscored the impact of the crimes on the victims’ loved ones, reminding the jury of the human life lost. De Hoyos closed her arguments by presenting a final photograph of Sylvia and Brianna as they were remembered by their family, not as victims but as cherished individuals.
The jury will now deliberate on the fate of Mendez, with the weight of the evidence and the emotional testimonies still resonating in the courtroom.
