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

A judge sentenced a Donna man to 20 years in state prison after he pleaded guilty to first-degree murder on Wednesday. Lenin Gonzalez, 34, of Donna pleaded guilty to stabbing Javier Olvera with a knife on Jan. 15, 2017. Olvera later died at a hospital. Investigators believe the murder resulted from a dispute over money during a drug deal on the 6000 block of North Victoria Road. Investigators later found a bloody knife believed to be used in the murder during a search warrant at a suspect’s house. Investigators arrested three suspects in connection with Olvera’s death: Gonzalez, then 23-year-old Agustin Mendoza and then 26-year-old Francisco Hernandez. On March 27, 2018, Hernandez pleaded guilty to Olvera’s murder and was sentenced to 30 years in state prison. Mendoza is set to return to court for a pre-trial hearing later this month.

Cold Case Spotlight

On May 23rd, 1990, the dead body of Laura Guerra,22, was found in a wooded area across the road from the Rio Motel in Rio Grande City. The RIO MOTEL is located at 1111 W. Main Street. Investigators believe that Guerra was murdered at another location, possibly at the motel, and that her body was dumped in the wooded area. Autopsy results indicate that Guerra was killed three days earlier by a gunshot wound to the head. Several clues were followed, but the case went cold. Texas Rangers and the Starr County Sheriff’s Office have reopened this case, and are seeking the public’s help for information to help identify Guerra’s killer. Investigators believe that a possible witness may have information on this crime, and are asking for the public’s help in identifying a person known in the area, in 1990, known as "Gaston Garza," or "Mariano".
