The Harris County Sheriff’s Office has rolled out a new cold-case webpage, going live on April 10, 2026, to spotlight unsolved homicides in unincorporated parts of the county, including the 2015 murders of Don and Reda Rentz. The goal is simple and overdue: put all the key case details in one place so the public can easily review them and send in tips. For the Rentz family, which has been waiting more than a decade for answers, investigators say leads are still scarce and every new set of eyes could matter.
In 2015, Don (84) & Reda (80) were murdered in their Harris County home. 10+ years later: no suspect. No motive. A family still waiting. We’ve launched a NEW Cold Case website to spotlight cases & make submitting tips easier.

HCSO Launches Cold-Case Hub
The sheriff’s office announced the new resource on X, saying the site will “spotlight cases & make submitting tips easier,” as posted by the Harris County Sheriff’s Office. The post links to an Unsolved Homicide Cold Cases page that lists investigations in unincorporated Harris County and provides direct contact information for detectives. Deputies say the hub is meant to shake loose dormant leads and give families and residents one central place to study case details instead of hunting through scattered releases and old coverage.
Case Details: Don and Reda Rentz
Don and Reda Rentz, ages 83 and 80 at the time, were found dead inside their Kings River Village home in Atascocita on March 7, 2015, after a neighbor went to check on the couple, according to the Houston Chronicle. Investigators said the pair had suffered blunt-force trauma and that robbery appeared to be the suspected motive. The couple had last been seen alive on February 26, 2015. Even with an increased reward and repeated public outreach over the years, officials have not named any suspects.
Why the Site Could Matter
The HCSO cold-case hub includes case summaries, detective contact information and online tip forms, as outlined by the Harris County Sheriff’s Office. The page highlights the Homicide Unit’s pledge to keep pursuing leads and to present “our most challenging cases to you” in hopes that someone recognizes a detail that did not seem important years ago. Investigators say that putting more case files in front of the public can nudge witnesses, neighbors or relatives to finally share information they have been sitting on.
Where To Send Information
Anyone with information about the Rentz slayings can contact Crime Stoppers of Houston by calling 713-222-TIPS (8477), texting TIP610 to 274637, or submitting a tip through Crime Stoppers. News coverage from past years notes that Crime Stoppers and other donors pushed the reward to roughly $20,000 after the case went cold, as reported by Click2Houston. The HCSO cold-case page also lists phone numbers for its homicide unit and an information line for tipsters who prefer to work directly with investigators.
For the Rentz family, which has repeatedly pleaded for answers since the killings, the new hub is at least a sign that the department is keeping the case active. The sheriff’s office says it is banking on renewed attention to generate the kind of lead that can finally turn a decade-old mystery into an arrest and some measure of closure, a hope underscored in the HCSO post. Anyone with information is urged to use the channels listed on the sheriff’s cold-case page or contact Crime Stoppers.
