Rio Grande Valley Friends and Families of Murdered Children

Proudly Introduces the RIO PROJECT COLD CASE HOMICIDE DATABASE: A Regional Initiative to Spotlight Unsolved Murders and Amplify the Voices of Victims and Their Families

The Rio Grande Valley Families and Friends of Murdered Children (RGV-FFOMC) is honored to announce the launch of the Rio Project Cold Case Homicide Database—a first-of-its-kind initiative designed to centralize and bring public attention to unsolved homicide cases throughout the Rio Grande Valley. This comprehensive and publicly accessible database will be a powerful tool for elevating awareness, supporting grieving families, and encouraging renewed investigative efforts.

Phase I – County Coverage:
The initial rollout will include unsolved homicide cases submitted from the following four counties:
  • Hidalgo County
  • Cameron County
  • Starr County
  • Willacy County

Each entry will be verified and submitted by either:
  • Local law enforcement agencies, or
  • Surviving family members seeking to keep their loved one’s memory alive and case visible.
RGV-FFOMC plans to expand the database to include additional counties across the region as resources allow.

Why This Matters:
Keeping a homicide victim’s case in the public eye not only honors their memory but also increases the likelihood of generating new leads, witnesses, or information that may help bring justice—visibility matters. Awareness saves cases.

How to Submit a Case:
Families or law enforcement agencies wishing to submit an unsolved homicide case for inclusion may do so by completing the official Case Summary -
Cold Case Submission - Google Forms

Submission Form
. Submission does not guarantee immediate inclusion; all entries are subject to verification and review.

⚠️ Please Note:

Rio Project Cold Case is not a private investigative service. This initiative is strictly for public awareness and advocacy purposes. All investigative matters remain under the jurisdiction of the appropriate law enforcement agencies.

CAMERON COUNTY, Texas (ValleyCentral) — A knock on the door from a stranger lead to the abduction and murder of a local man. 33 years later, the murder of Eduardo A. Cuellar remains unsolved with no arrests. On October 18, 1988, at approximately 6 p.m. two men arrived at Cuellar’s front door asking for him by name. Cuellar approached the men outside his home when a man put a gun against his rib cage area and forced Cuellar into a black Chevy Balzer where a third man was waiting. The gunman was described as a Mexican man with a mustache wearing a baseball cap, weighing approximately 160 pounds with a height of 5 feet 6 inches, and is estimated to be around 30 years old, according to the Cameron County Sheriffs Office. Family members of Cuellar followed the Chevy from a distance. The vehicle turned around after Cuellar’s body had already been left on the side of the road with multiple gunshot wounds. Investigators say the suspect’s last name may be “Leal” or “Lopez.” This investigation remains active and unsolved. If you have any information on this case, please call the Cameron County Crime Stoppers at their hotline: (866)-350-5551 or (956)-350-5551.
