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.

BROWNSVILLE, Texas (ValleyCentral) — A 30-year-old man survived a kidnapping only to be captured and murdered a few years later, authorities continue to look for his murderer two decades later. As the lone survivor in a drug-related kidnapping, Genaro Melendez believed he was in the clear for years but he was kidnapped again in 2001. Melendez was lured into a vehicle at approximately 2:30 a.m. on June 5, 2001, to never again be seen alive. A few days later Melendez’s body was discovered in an empty field, near Boca Chica Beach. His body was found “tied up and had sustained three shots through the head,” according to Cameron County Sheriff at the time, Conrado M Cantu. Sheriff Cantu told reporters from the Brownsville Herald that Melendez’s body appeared to have been killed “execution-style.” The investigation revealed that Melendez’s murder was drug-related. The Cameron County Sheriffs Office does have a person of interest in this case, however, no arrests have been made and the case remains active. 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.

Cold Case Spotlight

August marks 15 years since Ruben “Yiyo” Tarin de Patino was found murdered. Yiyo, 21, was found dead East of Wisconsin Road in the city of Edinburg in 2005. “He was found burned,” said Hermelinda Chavez with the Hidalgo County Major Crimes Unit. Yiyo was described by family and friends as confident and proud. “She was described as a person who didn’t like to hide her lifestyle,” said Chavez. “She was never ashamed of how she dressed and she was very outgoing with a lot of friends.” Yiyo was last seen by her mother on July 27. She had met several friends and her sister during the day and assisted another friend with car trouble. Yiyo came home and told her mother she was meeting yet another friend, this was around midnight. “She would visit a lot of nightclubs around the area, McAllen and Edinburg,” said Chavez. “She was not aggressive but definitely defended herself.” Chavez added all of the friends that Yiyo met on July 27 were interviewed and had alibis. Investigators and family never confirmed who she had met, according to Chavez. “Family never knew who she met, it was never confirmed,” said Chavez.
