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

HARLINGEN, Texas (ValleyCentral) — Always chosen for jury duty, a man went missing days before trial. His family searched across borders when his body was discovered shot multiple times in a canal. Three decades later, the murder of Joseph Michael Escobedo remains unsolved. Escobedo was a student at Texas Southmost College and a member of the Knights of Columbus, with ambitions to possibly become a teacher, according to reports at the time. The 23-year-old man said goodbye to his family for the last time as he headed out the door for a night out on January 2, 1992. The next day, Escobedo’s parents noticed their son’s absence as his bedroom seemed untouched. Growing concerned following a call from Escobedo’s boss stating he had not arrived for his shift, his father began a search. Escobedo’s father searched jails and police stations in Harlingen, Brownsville, South Padre Island, Reynosa, and even Matamoros. However, there was no trace. After waiting 24-hours, the Escobedos filed an official missing person report with the Brownsville Police Department. On January 4, 1992, Escobedo’s “bullet-riddled” body was discovered that same afternoon in a canal along Schmoker Road, outside Harlingen city limits near Valley International Airport, according to the Cameron County Sheriff’s Office. Authorities said Escobedo was shot eight times with two different weapons. Investigators spoke with Escobedo’s friends who claimed that they last saw him leaning against a car in the parking lot at the Genesis nightclub in Brownsville. Police were not able to determine whether he left by himself or whether someone picked him up. Feeling like they took a “part of [her] heart out,” Escobedo’s mother explained to investigators that her son was a good citizen. Emphasizing how much he enjoyed jury duty, as it was one of his “favorite hobbies.” The mother told reporters with the Valley Morning Star at the time that Escobedo was actually expected in court within days of his disappearance and murder. Escobedo was set to attend the trial of a county case on January 6, 1992. Lieutenant Ernesto Flores with the Cameron County Sheriff’s Office told reporters at the time that they could not find a motive. Adding that Escobedo “had a lot of friends, but few enemies.” In their son’s memory, the Escobedos planted a white rose bush under Michael’s bedroom window shortly after his death. Escobedo’s mother shared that she takes the roses that have blossomed to his grave. 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.

Cold Case Spotlight

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.

Cold Case Spotlight

BROWNSVILLE, Texas (ValleyCentral) — A 30-year-old man survived a kidnapping only to be captured and murdered a few years later, authorities continue to look for his murderer two decades later. As the lone survivor in a drug-related kidnapping, Genaro Melendez believed he was in the clear for years but he was kidnapped again in 2001. Melendez was lured into a vehicle at approximately 2:30 a.m. on June 5, 2001, to never again be seen alive. A few days later Melendez’s body was discovered in an empty field, near Boca Chica Beach. His body was found “tied up and had sustained three shots through the head,” according to Cameron County Sheriff at the time, Conrado M Cantu. Sheriff Cantu told reporters from the Brownsville Herald that Melendez’s body appeared to have been killed “execution-style.” The investigation revealed that Melendez’s murder was drug-related. The Cameron County Sheriffs Office does have a person of interest in this case, however, no arrests have been made and the case remains active.
