Houston police are reopening the investigation into the death of Joann Zamora, a woman whose remains were discovered in north Houston more than three decades ago, after she was recently identified through genetic genealogy.
Zamora’s body was found on Sept. 8, 1992, in an overgrown field in the 500 block of Rittenhouse.
At the time, investigators ruled her death a homicide by blunt force trauma, but her identity remained a mystery for more than 30 years. She was buried in the Harris County Cemetery under a marker labeled only “unknown.”
Volunteers with Moxxy Forensic Investigations helped launch a crowdfunded effort last year to extract DNA from her remains. That testing, paired with family tree research, confirmed her identity earlier this year.
Sgt. Richard Rodriguez, supervisor of HPD’s Homicide Cold Case Unit, said the breakthrough now allows detectives to re-examine the case.
“Now that we’ve identified her, the first thing we’re going to do is create what we call victimology,” Rodriguez said. “We need to know who she was, what she was doing, who she was with, what associations she had. That’s one of the biggest things we have to do right now in order to rebuild her life back then.”
Rodriguez said there are currently no suspects. He noted Zamora’s relationships at the time will be a focus of the investigation, especially since she was never reported missing.
“That, to me, is very suspicious,” Rodriguez said. “It kind of leads me to believe that whoever was with her maybe did something and didn’t want anybody to know.”
Zamora’s cause of death was blunt force trauma.
Rodriguez described the attack as “very painful,” based on the original autopsy. When her body was found, it had been in the field for several months and was in a decomposed state, which limited evidence collection.

Police said Zamora’s body was discovered by a neighbor who often searched the vacant lot for discarded items. The site is now occupied by a church.
Rodriguez acknowledged Zamora’s troubled past but stressed that her lifestyle did not diminish the value of her life.
HPD officials said advancements in forensic science, including genetic genealogy, are helping breathe new life into cold cases, though funding and the ability to meet courtroom standards remain challenges.
Houston police are urging anyone with information about Zamora’s death to call Crime Stoppers at 713-222-TIPS. A $5,000 reward is being offered for information leading to an arrest.
