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.

Cold Case Spotlight

Hidalgo County Sheriff Eddie Guerra on Tuesday identified the victim of a homicide that occurred Monday night. Gerardo Alberto Gomez Martinez, 38, of Mission was found dead near Alton. As CBS 4 News previously reported: At about 10 p.m. Monday, the Hidalgo County Sheriff’s Office dispatched deputies to investigate a call about shots fired near the intersection of Mile 7 and North Los Ebanos Road, said Sheriff Eddie Guerra. Investigators found a 38-year-old Hispanic man — wearing blue jeans and a red jacket — dead at the scene. “There was a four-door Nissan passenger car here at the scene. We believe that the victim got to this location in that car,” Guerra said. “The neighbors do not recognize the victim nor the vehicle.” Guerra said investigators determined the Nissan’s license plates didn’t match the vehicle.

Cold Case Spotlight

Investigators with the Starr County Special Crimes unit worked lead after lead trying to figure out who murdered Roman Ramirez, Jr. But starting with the New Year, those leads have gone cold. Investigators told Action 4 News that its TMs been a seven long months of chasing leads that went nowhere. Months of unanswered questions have also taken their toll on the family. Ramirez was shot and left for dead on the side of La Blanca Road in the Guerra Garza Subdivision on a sunny June 2011 afternoon. Investigators said it was an area that Ramirez would frequently travel walking up and down La Blanca Road. They said with no witnesses coming forward, their investigation has come to a standstill. Authorities are hoping a cash reward will bring someone forward someone who can help bring closure to a grieving family. Starr County Sheriff TMs Office Investigator David Ibarra spoke to Action 4 News about the case. His family reaches out to us on a regular basis, Ibarra said. We’d really like to help them out by putting the person or persons responsible behind bars.”
