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 47-year-old man has been charged with capital murder after authorities say he confessed to shooting and killing two women in rural Edinburg on Tuesday evening. Alvaro Medrano, 47, of Edcouch was charged with capital murder, a capitol felony, on Wednesday. A Hidalgo County Justice of the Peace set bond at $2 million. At about 6:48 p.m. on Tuesday, Sheriff’s deputies responded to an area near Sunflower Road in rural Edinburg in “reference to a 911 caller reporting that he had shot his wife“, according to a news release from the Hidalgo County Sheriff’s Department. Deputies located Medrano as he was walking away from the location, and detained him without incident near Farm-to-Market Road 493 and Farm-to-Market Road 2812, according to the news release. When deputies responded to the Medrano’s residence, they found two female bodies inside of a vehicle with gunshot wounds to the head. The bodies were identified as Medrano’s wife, 30-year-old Olga Espinosa, and Medrano’s mother-in-law, 52-year-old Irene Espinosa, according to the news release. Hidalgo County Sheriff’s Office investigators and Crime Scene Specialists collected evidence from the scene, including the handgun that was used in the shootings, according to the news release. After an investigation, the Hidalgo County Sheriff’s Office “learned that Medrano had streamed his confession on Facebook Live, while walking away from the crime scene,” according to the news release. Investigators are working with the Facebook Law Enforcement Compliance Department to preserve the livestream as evidence. During an interview, Medrano confessed to killing his wife and mother-in-law in a domestic disturbance due to infidelity, according to the news release. The Hidalgo County Sheriff’s Office encourages anyone who may be a victim of domestic violence to seek help from their respective law enforcement agencies.
