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.

Hidalgo County Sheriff Eddie Guerra announced Thursday that a 40-year-old Edcouch man recently confessed to killing a woman and dumping her body in a septic tank. Aristeo Garcia Cervantes, 40, of Edcouch confessed to killing a woman and hiding her body in a septic tank, Guerra said Thursday morning during a news conference at the Sheriff’s Office. Cervantes said he killed the woman roughly 10 to 12 years ago and didn’t remember her name, Guerra said, adding that investigators believe the murder occurred in 2004... The Sheriff’s Office started investigating the murder on July 26, 2017, when someone called to report human remains in a septic tank, Guerra said. Investigators went to a home near Edcouch, where Cervantes’ daughter and her boyfriend said they’d been having problems with the septic tank. When the boyfriend and another man attempted to fix the problem, they found a woman’s boot in the septic tank, Guerra said. After they removed the boot, they found a large bone — and called the Sheriff’s Office. Investigators sent the body to a private forensic lab in Virginia for DNA testing, Guerra said. The Sheriff’s Office researched missing women and welfare concerns during the time period, attempting to identify the woman. Investigators are currently talking with a family.

CAMERON COUNTY, Texas (ValleyCentral) — A knock on the door from a stranger lead to the abduction and murder of a local man. 33 years later, the murder of Eduardo A. Cuellar remains unsolved with no arrests. On October 18, 1988, at approximately 6 p.m. two men arrived at Cuellar’s front door asking for him by name. Cuellar approached the men outside his home when a man put a gun against his rib cage area and forced Cuellar into a black Chevy Balzer where a third man was waiting. The gunman was described as a Mexican man with a mustache wearing a baseball cap, weighing approximately 160 pounds with a height of 5 feet 6 inches, and is estimated to be around 30 years old, according to the Cameron County Sheriffs Office. Family members of Cuellar followed the Chevy from a distance. The vehicle turned around after Cuellar’s body had already been left on the side of the road with multiple gunshot wounds. Investigators say the suspect’s last name may be “Leal” or “Lopez.” This investigation remains active and unsolved. 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.

BROWNSVILLE, Texas (ValleyCentral) — In 1992, officers received a call about a body found along the banks of the Rio Grande. Nearly 30 years later, the case remains unsolved. On Oct. 26, 1992, the Cameron County Sheriff’s Office received information that there was a body buried along the banks of the Rio Grande in the area of FM 1419. The next day, investigators found a shallow grave with the body of a man wrapped in a blue tarp. After forensic testing, the body was identified as 17-year-old Marcelino Velazco. Velazco had previously been reported missing. He was last seen on Aug. 22, 1992, getting inside of a small, red two-door T-top vehicle at the 6000 block of Camelia Street in Brownsville. The Sheriff’s Office said that there were two “unknown” men in the vehicle. An autopsy revealed that Velazco was struck by a bullet in the upper spinal cord. In a 1992 report by the Valley Morning Star, Cameron County Sheriff’s Office Lt. Ernesto Flores said the murder was “drug-related”, stating Velazco had been involved in trafficking. Authorities said that the murder could have been connected to the slaying of three other men who were found on a Mexican ranch. Previous reports revealed that the suspects tied Velazco with a heavy rope and that his remains had been clawed by animals roaming the area. According to the Valley Morning Star’s report, Velazco’s mother told deputies that two men in Matamoros had confessed to the murder. The two men, Victor Rivera, 19, and Heriberto Ortego Ruiz, were incarcerated for confessing to the murder of three Matamoros residents. “I talked to Mexican authorities, and they said the men arrested never confessed to killing Velazco,” Flores said in the Valley Morning Star’s report. Those with information are asked to contact the Cameron County Crime Stoppers at (956) 350-5551.
