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.

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.

Cold Case Spotlight

The 41-year-old man was found in a field on a slab of concrete on November 10, 2006, when a driver passing through the area noticed something and flagged down a patrol officer with the Pharr Police Department. De Leon was discovered at approximately 12:38 p.m. at 1615 West Expressway 83 in Pharr. The teacher was found with a gunshot wound to his head, his hands tied behind his back, and his feet bound by a belt, according to the Pharr Police Department. Investigators found no form of struggle at the location, however, they believe that De Leon was not murdered at the field but left thereafter. Authorities do not believe that De Leon’s murder was drug-related. An autopsy later revealed De Leon had blunt force trauma to his “head, neck, and upper chest area.” De Leon was reported missing by his mother later that day at approximately 6:10 p.m., just hours after authorities discovered his body. Officials visited the De Leon residence and confirmed with the mother that her son had been murdered. According to the Pharr Police Department, Investigators currently have no leads. This investigation is ongoing. If you have any information on this case, please call The Pharr Crime Stoppers at (956)-787-8477.
