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

BROWNSVILLE, Texas (ValleyCentral) — Jose Guadalupe Martinez was found murdered in his office in 2017. Investigators have been able to narrow the timeline of when he was killed, but the case still remains unsolved. At 7:49 p.m. on March 15, 2017, officers responded to Milo’s Tire Shop, located at 2485 Military Highway in Brownsville after a body was found. A man discovered the body, and went to a neighbor who was close by. When the two returned, a third man was there at the scene. The three men then called police and waited for officers to arrive. Upon arrival, officers found Martinez face down, in a pool of blood in his office. He had a gunshot wound to his head, and investigators found one bullet casing at the scene. The man who originally discovered Martinez’ body arrived at the store at 7:35 p.m. to pay for some rims he had purchased. Investigators at the scene later found a receipt Martinez had from a purchase at a dollar store at 7 p.m. that same day. With this information, they were able to determine that Martinez was murdered at some time between 7 p.m. and 7:35 p.m. However, Brownsville police said they have “no leads whatsoever,” with the case.

Cold Case Spotlight

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.

Cold Case Spotlight

It’s one of the more infamous ‘whodunit’s’ in all South Texas. A young, Harlingen mother found with 25 stab wounds, a cut throat, and a broken neck. No arrests were ever made in the killing of 23-year-old Candy Mora-Fletcher. For 45 years, the case file remained quiet, until a new lead on the decades-old crime presented itself. “Once the investigator was able to put the entire case together where it made sense to him, it didn’t take long to realize there was one prime suspect that was left out there and everything seemed to point to him, and that was a man by the name of Lewis Brewster,” says Commander Osborne of the Harlingen Police Department. “He did allude to the fact that he knew we were looking for him and we’d arrest him if we came back and there seemed to be some sort of solace with that,” says Osborne. Last November, the case took its final blow. Brewster passed away due to complications from diabetes. Mora now rests at the Monta Meta Memorial Park in San Benito. Thursday marked the 47th anniversary of the crime. Before the suspect died, D.A. Saenz says the prosecution was on the verge of presenting the case to the grand jury. That move was only two weeks away.
