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.

CAMERON COUNTY, Texas (ValleyCentral) — Murder remains unsolved after 18 years since a body of an almost unidentifiable body was discovered in a canal. Gregory Allen Meredith, 43, body was discovered floating in a canal by a fisherman on May 7, 2003. Cameron County Sheriffs deputies responded to the scene located along Old Port Isabel Road and Highway 100 at 6:45 p.m. Deputies responded after receiving a call from the Laguna Vista Police Department. Officials could not immediately identify Meredith’s body due to severe water damage as well as the fact that his teeth had all been removed, making it impossible to check dental records. Meredith’s body was believed to have been in the canal for two to three days. Meredith’s body was initially reported to have two gunshot wounds, one behind his ear and another at the base of his skull. A preliminary autopsy later revealed that Meredith had eight bullets lodged in his skull. Cameron County Sheriffs Spokeswoman at the time, Elizabeth Anguiano told Valley Morning Star reporters that Meredith was identified as the Federal Bureau of Investigation was able to “get two prints from him.” Fingerprints matched the criminal file of Gregory Allen Meredith out of Bastrop, located southeast of Austin. Authorities told reporters they did not believe the murder was the result of a robbery as Meredith had $115 dollars in his pocket. According to CCSO Meredith was believed to have been involved with a small organization that trafficked meth from Austin. CCSO does have a suspect, however, no arrests have been made. This investigation is ongoing. 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.

HARLINGEN, Texas (ValleyCentral) – A woman well known by the community disappeared with no trace only for her flesh-eaten body to be discovered days later in a resaca, leaving authorities with no leads. 23 years later, the murder of Maria Marisella Gonzalez remains unsolved. Also known as “Marcie,” Gonzalez was a dancer at Crazy Horse Topless Bar. Gonzalez was last seen spending time in Harlingen’s La Placita district on June 8, 1998. Witnesses told authorities that Gonzalez was seen entering a vehicle with a man. The dancer was discovered dead in a resaca near Hudson Road outside San Benito on June 14, 1998, according to the Cameron County Sheriffs’ Office. Gonzalez’s body was found with multiple skull and facial fractures with her face flesh eaten away by “whatever lies in the murky waters.” The 35-year-old woman was identified as “Marcie” through her clothing, jewelry, and the tattoo of a rose on her right shoulder. According to an autopsy report released at the time, Gonzalez’s cause of death was determined to be three blows to the head and face delivered with a blunt object. Preliminary pathology reports ruled her death as a homicide. CCSO Investigator at the time Domingo Diaz told reporters that the agency has questioned all of Gonzalez’s acquaintances but had no leads. Diaz stated that he was sure that “someone saw… something.” As a rise in murders spiked during the time of Gonzalez’s death, reporters spoke with other county officials. Hidalgo County District Attorney Rene Guerra emphasized the importance of witnesses, stating murders like Gonzalez’s, that lack witnesses tend to go unsolved. This case remains an open investigation. Individuals with any information on this case are asked to call the Cameron County Crime Stoppers at their hotline: (866)-350-5551 or (956)-350-5551.
