In a city as vibrant and resilient as Houston, the idea of an unsolved murder lurking in the shadows for over a decade is unsettling. But thanks to the tenacity of law enforcement and advances in technology, justice has finally been served in a cold case that had haunted a Houston family for 15 years. Jorge Trevino Cardenas, 52, has been sentenced to life in prison for the brutal 2009 murder of Domitila Alvarez, a mother of five. Harris County District Attorney Kim Ogg made the announcement on Thursday, offering a sense of closure to a family and community that never gave up hope.

“This was a horrific crime when it happened, and no one in law enforcement ever stopped looking for the killer,” said Ogg. “Even after the case went cold, investigators kept working on it, and when charges were filed, prosecutors were able to get justice for the victim and her family.”

A Cold Case Reignited

The chilling murder took place on April 24, 2009, when 38-year-old Alvarez went to her family's auto shop in Houston's Alief area. The evening, which began as a routine visit to handle business, quickly turned tragic. Hours later, her family found her lifeless body in the office of the shop, brutally stabbed multiple times. It was a gruesome crime with no apparent motive, leaving investigators perplexed and desperate for leads.

Alvarez's murder scene painted a horrifying picture. In addition to her bloodied clothes, investigators discovered bloodstains leading out of the office—on the door, on security bars, and even on a parked truck outside. Yet, the trail of evidence offered no clear suspect, and despite relentless efforts by the police, the case eventually went cold.

Enter 2021, when the Houston Police Department’s Homicide Division Cold Case Squad took another look at the evidence. Armed with advanced forensic technology, investigators were able to reanalyze DNA samples taken from the crime scene. The results? A match was found—one that pointed directly to Jorge Trevino Cardenas.

The DNA Trail That Solved the Mystery

At the time of his identification, Cardenas was already serving time for an unrelated crime—sexual assault of a child, for which he was convicted in 2014. A DNA sample collected during that case had been entered into a national database, unknowingly waiting to solve a murder mystery.

The DNA linked Cardenas to multiple locations at the crime scene. His blood was found not only on Alvarez’s clothing but also on the door, security bars, and truck outside the shop. Investigators surmised that Cardenas had cut himself during the altercation, leaving a literal trail of evidence that would later secure his conviction. As Assistant District Attorney Christopher Condon aptly stated, “DNA does not lie, it does not forget—it waits.”

The blood trail ultimately led prosecutors to connect Cardenas to the crime, and by January 2023, he was formally charged with murder.

A Conviction 15 Years in the Making

After a four-day trial, a jury convicted Cardenas of murder. On Thursday, he was sentenced to life in prison. However, under Texas law, Cardenas will be eligible for parole after serving at least 30 years—a prospect that provides only cold comfort to those who loved Alvarez.

Condon, who prosecuted the case alongside Assistant District Attorney Michael Simons, highlighted a critical piece of evidence during the trial: a witness who knew Cardenas testified that he lived near the auto shop and regularly carried a long, fixed-blade knife with a serrated edge—matching the type of weapon used in Alvarez’s murder. Medical experts corroborated this, further tightening the case against Cardenas.

While no amount of justice can reverse the tragic loss of Domitila Alvarez, her family can finally take solace in knowing that the man responsible for her murder has been held accountable.

The Power of Persistence

This case serves as a powerful reminder of the enduring nature of justice. Thanks to the persistence of the Houston Police Department’s Cold Case Squad and the unwavering dedication of prosecutors, a 15-year-old mystery has been solved, and a dangerous man is behind bars.

Harris County District Attorney Kim Ogg commended the hard work of investigators: “Even after the case went cold, they never gave up. The relentless pursuit of justice in this case is a testament to their dedication.”

For Alvarez’s family and the broader Houston community, the conclusion of this case brings not only relief but also hope—hope that no matter how much time passes, justice will find its way.

A City That Won’t Forget

Houston is no stranger to challenges, and stories like this one remind us that the fight for justice is long but worth every effort. As we reflect on this case, we also honor the memory of **Domitila Alvarez**, a loving mother whose life was cut short in an act of senseless violence. Her memory lives on, not only in the hearts of her family but also in the community that stood by her side through the years, never forgetting and never giving up.
